I have a brand new trailer and the factory put the axle on crooked, and the location isn’t quite right either for the tongue weight to be correct when hauling my Harley, so I planned to remove the axle, cut off the mounts, and put it all back straight, and move it forward a small amount for the balance, but this may be a better solution, or upgrade.
Thank you for the feedback! Check out the following link for more information on this axle-less trailer suspension system. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Great product to upgrade an older trailer to even better than when it was new, even better for a new trailer and it looks like it will be a weight saver too.
These are a great replacement for a factory axle and leaf springs. With this kit you will have higher ground clearance because you don't have an axle. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Thank you for sharing this with us and others! This is a great kit and it's very straight forward to get installed. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
These are only good for lightweight use. Anything that will exceed 5k lbs use axels. These are also prone to swaying. Especially after they have been used for a while. They are good for adventure/teardrop type campers. Very easy to raise or lower them with this setup. Make sure to elongate the holes drilled for them and test before welding. You might find yourself pulling a trailer that is pulling to the side.
You can use this design by Timbren for a number of uses that exceed 5,000lbs or more. I was quoted and plan on buying their products for my Black Iron/Full Framed Tiny House on Wheels. I’m just waiting to catch up on other stuff before I redo the suspension for my trailer. I own 8 old trucks as well so they take up a bunch of my money haha.
You can use the methods that you are referring to if you don't want to be able to remove it easily for maintenance or replacement. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
These suspensions do require lubrication! you must lubricate them if you want long life out of the pivot bushes, that is why there is the grease nipple in the bottom of the trailing arm

That's not a bad idea either. We've also used a paper towel to hold it in the wrench or socket. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Axless system but it has an axle in the front, or do you call a a "stability bar" and then each side is held in with six bolts so now you're weakening the frame by drilling these holes all over the place in it so in a few years the trailer will break in half from all the rusting, then what happens when all of the rubber cushions dry rot

These look really good. One of the things I worry about with my leaf-sprung cargo trailer camper is breaking springs when camping in remote areas off-road. Do you know if Timbren has tested these to failure? Any idea what the “weak link” is and what good emergency repair parts would be?
This kit would be great for exactly what you are wanting to do! There is nothing to get in the way when going off road or to get caught in the leaf springs. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
That type of drill would make it a bit easier with drilling the holes in the frame of the trailer. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
It will depend on how your trailer was built but on this trailer the cross piece was higher than the trailer supports. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Can you elaborate on the difference in travel between the axle less system and the leaf spring system and ride characteristics which one would be a softer ride?
This axle is too heavy for my application, but I found one that was suitable for a lightweight trailer weight.. Designing a hard side pop up motorcycle camper I had to use that style to cu enough weight to make it usable.

Sometimes the 3500 is a necessary selection, as the smaller Timbren may not fit the hub you are using. I believe you can have the 3500 de-rated, if that makes sense.

I think they will work well for a drop deck trailer , 4 should be good enough in the 3500lb that way 10k weight will be perfect . Trailer will stay flat even parked with a load no tilt or tongue jack need. I've built other trailers but the full axles for drop ones won't work to well.

I run timbrin bump stops on the front ends of my plow trucks and there fucking amazing they take so much weight off the suspension and the rubber timbrins take the weight and I run road masters in the rear to take the weight I took of the air bags off all my trucks and run them on the rears now best decision I ever made and they also take body role out
Trimbren bump stops are a great add on for the front suspension on trucks that have a lot of weight such as a snow plow. Thank you for sharing this with us and others that might be looking for something to solve a similar issue.
The old leaf springs on this trailer were worn out to the point where they needed replacing. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
how does this compare to a torsion axle? i have had good luck with the torsion axles on my 10,000lb work trailer. had lots of wear and maintenance on the leaf sprung axles on my car trailer looking to change at some point.
These axle-less systems are a bit different than a traditional torsion axle. The axle-less system is nice because if you hit a bump on the one side of the trailer, the other side of the trailer does not recoil from the bump.

We used scare tubing with 1/4" wall thickness because we wanted it to be stout enough to handle the loads we are going to carry. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Is it okay to weld this system in place, or does Timbren recommend not welding? Also, what's the weight rating? Do they make these to handle up to 5k Lbs. each to replace a 10k axle?
You can weld this system in addition to bolting it to the trailer frame. We have many different sizes available to match what your trailer needs. www.etrailer.com/dept-pg-Trailer_Leaf_Spring_Suspension-pt-Axle_Replacement_System.aspx
We have an axle-less system designed for tandem axles. Check it out in the following link. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/TSR7000T05.html
Many people have used this for off road trailers. It is really nice because you don't have to worry about the axle hitting anything when you are out on a trail. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
We are happy to help! You will need a kit that is rated for more weight. Check out the following link to see the kit we would recommend for your set up. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/TASR5200S03.html
This kit is going to be a lot easier for most people to get installed. It is harder to install a weld on kit. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
I am interested this system for my 2023 intech luna rover with 5 bolt lugs , i contacted etrailer ( adam ) he asked me to call timbren which best fit for my trailer , timbren rep can't recommend instead send me all the specs sheets and im not experts with those specs, im interested with this parts TASR35HDS07 base on your experty can i still reuses all hubs and bearing, according to your video i can . Thanks and hope hear back from you
You'll want to check the linked product page, where we list the bearings that the unit is compatible with. You'll want to make sure it'll be compatible with your existing hubs/bearings. www.etrailer.com/Trailer-Axles/Timbren/TASR35HDS07.html
You can most definitely use this system to replace you boat trailer axle. You will want to make sure that you get the appropriate size to replace your factory axle. www.etrailer.com/dept-pg-Trailer_Leaf_Spring_Suspension-pt-Axle_Replacement_System.aspx
I suppose you could use these for many different projects. We do know that people sure do love them for swaping their trailer axles. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
All those holes drilled should have been soaked with anti-rust paint. Also all of the bolts should have had Loctiite applied to the threads. Torque specifications are not enough.
For a tandem trailer you can use two sets of the Timbren systems however a third set for triple axle trailers is too much. The third axle will scrub too much for the Timbrens take. They'll be independent of one another. Another option for tandem trailers is the Silent Ride www.etrailer.com/dept-pg-Trailer_Leaf_Spring_Suspension-co-Tandem_Axle-pm-Timbren.aspx These replace the suspension of a tandem trailer but you still use your standard axles. -Chuck S
Do not buy this suspension system I had and it failed a good design but poor( welding wells broke right down the middle of the weld ) the tow job cost me $2500 to get my trailer out of the desert just to the nearest town beware
The spring set up is actually better. E Trailer you should correct your techs mis information. The rubber/urethane has a progressive rate spring and you can see the tire actually come off of the road due to the slow rebound of a rubber spring vs steel spring. Also be concerned with toe and camber issue when loaded vs conventional .188 wall tube spring axle.
This trailer is a light weight trailer and did not have a load on it. This caused the bouncing action. This kit performs very well when there is more weight on it. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
You need to make sure that the hubs use the same bearings and grease seal as the spindle. You can either find the part numbers for these on the bearings and grease seal directly or you can use a digital caliper and measure the locations on the spindle that those parts ride to the nearest thousandths. Below is a link to our selection of hubs and drums as well as a link to an FAQ on bearings and seals. If you still need some assistance you can reach out to us directly here www.etrailer.com/customer-service.aspx www.etrailer.com/dept-pg-Trailer_Hubs_and_Drums.aspx www.etrailer.com/article-categories.aspx?productgroup=Trailer-Bearings-and-Races
The Timbren Axle-Less Trailer Suspension System will work well on a boat trailer. It has a heavy-duty steel construction which doesn't make it the best option for a salt water application, but it does have a black powder coat finish that helps to resist wear and corrosion and will hold up better than a standard painted axle in a saltwater environment. The Timbren Axle-Less system will have normal wear and tear as long as it is taken care of. The spindles use the EZ Lube feature which allows you to grease the zerk fitting without having to take the whole hub off. This is a great time saver option that some people don't even know about. That is really the only maintenance that you will have to take care of.
Even though this axle-less system looks well built. I feel the trailer is going to be the fail point. With such a large amount of it hanging beyond the brackets it looks like a good spot to bend.
The cross tube and rubber bumpers will take the majority of the stress from the weight of the load. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
These are really cool. You won't have to worry about bottoming out because there's no axle. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
It is going to add extra support if there is not a cross member on the trailer in line with the Timbren Axle-Less System. The cross beam will not be included, you will have to supply it. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
This is pretty much a torsion axle. The only real difference I see is the method of dampening. I don't dislike it however I would like it better if the spindle and trailing arm were designed so that the spindle bolted to the underside of the trailing arm instead of on top. In the configuration shown here the 4 mounting bolts take up the all the load whereas if the spindle was bolted to the underside of the trailing arm the trailing arm would take more of the weight and the bolts would more or less keep the spindle in place.
This system would do just fine in light offroad conditions. Check out the following link for more information on this kit. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Price varies depending on your application. You can view more information at the link below. www.etrailer.com/s.aspx?qry=&furl=-pg-Trailer_Suspension-pm-Timbren
It is going to depend on the trailer that this kit is being installed on. If there is a cross member above where the new system will go then there is no need for the cross tube. But, I agree the tube should have been flush to outside of the bracket. Keep in mind the cross tube is not included in the kit. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
You could definitely weld this kit on if you had the means to do so but more people are going to be able to bolt it on with the tools they have in their garage. www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html

rod builder not everybody has a welder. This guy is showing it can be done by anyone with simple tools. Bolts are better for anyone that's not a professional welder. I have a welder but I'd still bolt it.

@Rowdy Haahaahaa....great description. This guy could definitely have been a stunt double for Ashton from the movie "Guess Who". Who says there aren't clones walking around?

These are only good for lightweight use. Anything that will exceed 5k lbs use axels. These are also prone to swaying. Especially after they have been used for a while.
They are good for adventure/teardrop type campers. Very easy to raise or lower them with this setup.
Make sure to elongate the holes drilled for them and test before welding. You might find yourself pulling a trailer that is pulling to the side.
Since this is a 3500 pound rated axle, it will not work on a five thousand pound trailer.
You can use this design by Timbren for a number of uses that exceed 5,000lbs or more. I was quoted and plan on buying their products for my Black Iron/Full Framed Tiny House on Wheels. I’m just waiting to catch up on other stuff before I redo the suspension for my trailer. I own 8 old trucks as well so they take up a bunch of my money haha.
Timbren has a 7000 lb model.
Great video guys, nice and clear explanation of everything going on.
Do you make these for 10 to 12K axles that use tandem duals?
Use stover nuts and loctite! After it's installed I'd also put a couple 1/2" tac welds from plate to frame and she's good for life
You can use the methods that you are referring to if you don't want to be able to remove it easily for maintenance or replacement.

In the UK we've had indespension units for 50 years or more, it's very rare to see a non-commercial trailer with an axle.
That's a clever way to do walking beams and leaf springs bouncing make pulling trailers hard on your automatic transmission
the loose fit tube steel cross member and two bolts one side look like an ineffective stiffening arrangement
A tip: watch series at Flixzone. Me and my gf have been using it for watching a lot of movies recently.
@Brooks Rafael yea, I have been watching on flixzone for since november myself :D
I need a 6 inch drop. I wonder if this will work with air bags to lower my trailer even more

www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Is it okay to weld this system in place, or does Timbren recommend not welding? Also, what's the weight rating? Do they make these to handle up to 5k Lbs. each to replace a 10k axle?
You can weld this system in addition to bolting it to the trailer frame. We have many different sizes available to match what your trailer needs.

Ok for dual axles?
We have an axle-less system designed for tandem axles. Check it out in the following link.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/TSR7000T05.html
So this suspension works basically like an independent suspension with no axle tube to get beaten and bent ?
You are correct. It helps to give you more ground clearance.

How well does this set up work off-road? I’m starting a trailer conversion and if this set up can handle light off-road I may have to grab a couple
Many people have used this for off road trailers. It is really nice because you don't have to worry about the axle hitting anything when you are out on a trail.

thank you for detail video
great ideal setup like will work 3500kg 4 wheels car trailer?
We are happy to help! You will need a kit that is rated for more weight. Check out the following link to see the kit we would recommend for your set up.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/TASR5200S03.html
I see that you bolted everything to the trailer, would you not recommend a weld on application?
This kit is going to be a lot easier for most people to get installed. It is harder to install a weld on kit.

I am interested this system for my 2023 intech luna rover with 5 bolt lugs , i contacted etrailer ( adam ) he asked me to call timbren which best fit for my trailer , timbren rep can't recommend instead send me all the specs sheets and im not experts with those specs, im interested with this parts TASR35HDS07 base on your experty can i still reuses all hubs and bearing, according to your video i can . Thanks and hope hear back from you
You'll want to check the linked product page, where we list the bearings that the unit is compatible with. You'll want to make sure it'll be compatible with your existing hubs/bearings.
www.etrailer.com/Trailer-Axles/Timbren/TASR35HDS07.html
Do these systems work on trailers that are imersed in salt water like boat trailers?
You can most definitely use this system to replace you boat trailer axle. You will want to make sure that you get the appropriate size to replace your factory axle.

@@etrailer cool, thanks.
A person could do a lot with these things....❓ like use it for the suspension on a bike build. Or other really cool projects.
I suppose you could use these for many different projects. We do know that people sure do love them for swaping their trailer axles.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
All those holes drilled should have been soaked with anti-rust paint. Also all of the bolts should have had Loctiite applied to the threads. Torque specifications are not enough.
Also, it helps if you haven't been drinking heavily when you are going to be shooting an install video 🤣
What about tandem applications? Is there a way to equalize the pairs or would it be independent?
For a tandem trailer you can use two sets of the Timbren systems however a third set for triple axle trailers is too much. The third axle will scrub too much for the Timbrens take. They'll be independent of one another.
Another option for tandem trailers is the Silent Ride www.etrailer.com/dept-pg-Trailer_Leaf_Spring_Suspension-co-Tandem_Axle-pm-Timbren.aspx These replace the suspension of a tandem trailer but you still use your standard axles.

Hello, I own a travel trailer camper with a 9,500lbs GVWR. Will this work with my camper as well?
I too have a travel trailer I'm interested in doing this too, did you ever do this to yours or did you decide not to. Thanks
How much speed can this axle less things handle?
Do not buy this suspension system I had and it failed a good design but poor( welding wells broke right down the middle of the weld ) the tow job cost me $2500 to get my trailer out of the desert just to the nearest town beware
Yikes, which model did you have and how heavy was your trailer?
@@RossFeighery I have the 2500 pound axle the material did not break it’s just a poor welding I would not buy another one
@@nielmadsen9806 I've never heard of this, maybe you got the axle's built on a Friday afternoon?
The spring set up is actually better. E Trailer you should correct your techs mis information. The rubber/urethane has a progressive rate spring and you can see the tire actually come off of the road due to the slow rebound of a rubber spring vs steel spring. Also be concerned with toe and camber issue when loaded vs conventional .188 wall tube spring axle.
This trailer is a light weight trailer and did not have a load on it. This caused the bouncing action. This kit performs very well when there is more weight on it.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
@@etrailer I’m familiar. I rate all of their springs.
Tandem axles?
You can use this in a tandem axle set up.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
this isnt a review of the product but more of an advertisement for it
Ya it seems a lot of companies on youtube don't know the difference between an overview and a review.
How do you know what hubs to buy to fit the axel? I don't want to buy the wrong hubs
You need to make sure that the hubs use the same bearings and grease seal as the spindle. You can either find the part numbers for these on the bearings and grease seal directly or you can use a digital caliper and measure the locations on the spindle that those parts ride to the nearest thousandths. Below is a link to our selection of hubs and drums as well as a link to an FAQ on bearings and seals. If you still need some assistance you can reach out to us directly here www.etrailer.com/customer-service.aspx

Use Cone bits to step up size.
Are these adequate for boat trailers?
The Timbren Axle-Less Trailer Suspension System will work well on a boat trailer. It has a heavy-duty steel construction which doesn't make it the best option for a salt water application, but it does have a black powder coat finish that helps to resist wear and corrosion and will hold up better than a standard painted axle in a saltwater environment. The Timbren Axle-Less system will have normal wear and tear as long as it is taken care of.
The spindles use the EZ Lube feature which allows you to grease the zerk fitting without having to take the whole hub off. This is a great time saver option that some people don't even know about. That is really the only maintenance that you will have to take care of.
Great vid, but the over spray looks sloppy. It would have only taken a min to tape it off. Or paint it ,then heat gun it, before u install it
It’s literally a offset axle and hub. Accept you use rubber instead of springs lol
Bet this things a fortune too
This is a sweet system! Those who have this kit on their trailers love it.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
This would be cool to put on the very end of a trailer to keep it from dragging on steep driveways leave it raised above the road .
We have a few skid wheel kits just for that! Check them out in the following link for more information.
www.etrailer.com/dept-pg-RV_Skid_Wheels.aspx
Can’t say I’d agree with not needing any lube just because it uses urethane bushings. Urethane squeaks sooo bad if you don’t regularly grease it.
why do you need brakez
to stop.... ?
Comprar ???
They tried rubber ride years ago the rubber wears out real fast then they vibrate a old idea that sucked
Even though this axle-less system looks well built. I feel the trailer is going to be the fail point. With such a large amount of it hanging beyond the brackets it looks like a good spot to bend.
The cross tube and rubber bumpers will take the majority of the stress from the weight of the load.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
So great! I've needed this info for a while.
These are really cool. You won't have to worry about bottoming out because there's no axle.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
What's the benefit of the square cross beam?
It is going to add extra support if there is not a cross member on the trailer in line with the Timbren Axle-Less System. The cross beam will not be included, you will have to supply it.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
It’s cost as much as a used trailer. Lol
This is pretty much a torsion axle. The only real difference I see is the method of dampening. I don't dislike it however I would like it better if the spindle and trailing arm were designed so that the spindle bolted to the underside of the trailing arm instead of on top. In the configuration shown here the 4 mounting bolts take up the all the load whereas if the spindle was bolted to the underside of the trailing arm the trailing arm would take more of the weight and the bolts would more or less keep the spindle in place.
The plate takes the load, not the bolts.
Very good ,but are you Paul Walker?
Would these hold up well for slight off-road use and rougher rides if I were to use them on a small tear drop trailer build
This system would do just fine in light offroad conditions. Check out the following link for more information on this kit.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
That is what they were designed for.
How much$$
Price varies depending on your application. You can view more information at the link below.
www.etrailer.com/s.aspx?qry=&furl=-pg-Trailer_Suspension-pm-Timbren
The cross tube should extend at least flush to the outside of the side plates to transfer load properly, leaving just inside is just stupid
It is going to depend on the trailer that this kit is being installed on. If there is a cross member above where the new system will go then there is no need for the cross tube. But, I agree the tube should have been flush to outside of the bracket. Keep in mind the cross tube is not included in the kit.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
etrailer.com looks like a great product guys , will have a look on your site. Sorry to be picky curse of being a structural engineer.
We are happy to help! You know what you're talking about and there's no shame in that. Let us know if there's anything else we can do to help.
Could you just weld it on?
You could definitely weld this kit on if you had the means to do so but more people are going to be able to bolt it on with the tools they have in their garage.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
Basically like the 2win double deck trailers you see here in Europe lol
Fantastic 👍
Thank you for the feedback! Check out the following link for more information on this kit.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
it looks like that system only has 2.5 inches of travel (which is terrible)
Holes? You have to be kidding!!! Ya' mean you don't have a welder?
What does a welder have to do with creating holes?
rod builder not everybody has a welder. This guy is showing it can be done by anyone with simple tools. Bolts are better for anyone that's not a professional welder. I have a welder but I'd still bolt it.
It's not crazy expensive either
What's the price?
These would be worth considering if they weren't so expensive. I could buy a complete trailer for less than the asking price of these.
This set up will require an anti sway bar
We have many people that pull trailers with this system on it everyday and they do not have issues with sway.
www.etrailer.com/Trailer-Leaf-Spring-Suspension/Timbren/A12RS440.html
You look like a more smarter, less dorkier version of Ashton Kutcher.
@Rowdy Haahaahaa....great description. This guy could definitely have been a stunt double for Ashton from the movie "Guess Who".
Who says there aren't clones walking around?
Or just buy a torsion axle.
You could also go with a torsion axle. People like how that suspension feels on the Timbren Axle-Less system.

Lol wtf an axleless trailer that you add a AXLE to...
Your not very bright
Watch the video dumbass.
