Вставка
- Опубліковано 29 чер 2024
- We very often get asked, how much faster is 3/8" air line compared to 1/4" air line? Well today we finally dig in and answer that question using our 2021 Toyota Supra rigged up with both 1/4 and 3/8 lines! As always if you have any questions leave them in the comments below!

i went with 1/4 to flex my air out
I want to bag my car so bad. Right now I’m on coilovers. How’s the comfort on bags? Also if you don’t mind me asking, what car do you drive?
Really the air line size should be based on the weight of your vehicle! 3/8 can be great for heavier vehicles to speed up the air out, where as 3/8 on a light vehicle can be too fast sometimes when trying to hit presets
@@bagriders Which air line size would you recommend for a Golf 5 R32 with about 1680 kg?
No you went with 1/4 because you couldn't afford 3/8
@@tonyx5705 my gr86 and camaro is bagged, 😭
Should have done a air up video also
We'll make sure to do that next time! It's a similar difference in terms of speed :)
Thanks for the video
Our pleasure!
wondering how much difference it would make with 1/2" over the 3/8"?
im told if you use a manifold (rather than individual valves) it wont make much difference, is that true?
The primary determinant here is the valve size. When utilizing a 1/4" valve, the variance in air release speed between 1/4" and 3/8" is small. Increasing the size of the valve along with a larger air line will maximize both air-out and air-up speeds. In this test, we compared the speeds of a 1/4" Air Lift 3P system with 1/4" air line to that of a 3/8" Air Lift 3P system with 3/8" air line.
Are all bags the same I want to order some replacements for the rear and front but not sure if I need to look up a part number
All the bags are different. Please reach out to us at 844-404-7344 or email sales@bagriders.com to confirm part numbers.
Do you recommend any products to even out the drop so that the rear doesn't go down first, but rather they car has a uniform drop?
Hey Arthur! We recommend flow controls for that!
My genesis airs out even .wish we could choose how it drops between even front first back first etc .happy with it dropping all even .
@@bagriders
Great, well now I'm tempted to put a sequencer on them so it drops one corner at a time.
Don't worry, you're not liable for my silly experiments. :D
@@alexbrumlik448 Flow controls will work best for getting the front and rear to air out evenly!
3/4 around here. 💨.
Should of also show the air up speed.
Thanks for the feedback! We can make an additional comparison for that!
Maybe someone can point me in the right direction. I’m about to purchase everything for my 88s10. Why are most manifolds 1/4”and the airride kits all come with 3/8 or 1/2” do all ports have to match??
1/4" Manifolds have been the most popular when it comes to sales and seems to work on 90% of the applications out there. Something to note about 3/8" vs 1/4" is that you can always slow down 3/8" but never speed up 1/4". For your S10 you can't go wrong with 3/8" in that case. If you checkout our offerings for the 88 S10 you can see we only offer 1/4" and 3/8" as we find 1/2" is extreme over kill while also it shares the difficulty of running the larger air line in tight areas. www.bagriders.com/vehicle/chevrolet-s10-1st-gen-rwd
do the actual struts and airbags come for 3/8 fittings? or do I just need the manifold to be for 3/8 fittings and hoses?
When ordering a full kit on bagriders.com we have the option of picking 1/4" or 3/8" line sizes. Whichever is chosen all the appropriate fittings will be included.
@@bagriders ok thanks for replying
Hey is the ride feeling better or worser with 3/8 instead of 1/4?
There is no difference in ride quality between 3/8 and 1/4!
The only difference between the two in form is 3/8 airs up and out faster than the 1/4. Wider air tubes = more air flow. It's said that 3/8 should be used for heavier vehicles like SUV's , trucks or Heavy muscle cars. Something to do with more difficulty/less precision when trying to set up different ride heights with 3/8 on a lighter vehicle. I have a Camaro 2SS. Not the lightest car but certainly not too heavy so I went with the 1/4. Also if you plan to do the install yourself the 1/4 will be easier than the 3/8's as its much easier to bend and run through nooks and crannys.
Does that include line and fittings? Or is it just the line? I know that's an odd question.
Great question! The comparison was done by swapping the entire system from 1/4" to 3/8", that includes the manifold/lines/fittings.
I'm on 1/4 3P system line currently... Can I upgrade line size to 3/8 and if so how could I go about doing it?!
If you are looking to increase the speed of your air up and outs your only option would be to buy a new manifold so you could run 3/8" fittings. www.bagriders.com/air-lift-performance-3h-3p-manifold-and-ecu.html
Mine seems to stutter while going down. Any idea why?
Feel free to email tech@bagriders.com and someone from our support team can help diagnose why that is happening! Make sure to include all the details on what management and struts you are running!
I have 1/4 but can I switch to 3/8 or I need to get the whole new airlift kit
You would want to swap manifolds so the PTC port matches your line size.
which one do you recommend for a civic 8th gen Sedan?
For the 8th Gen Civic we would recommend 1/4" air line.
What brand/model bags are on this car?
Our GR Supra is running our Super Low Air Suspension by Bag Riders.
Hmmmmm Looks like a mix would be best.
1/4 Rear, 3/8 Front
We do offer flow control valves to help level the car out during air out. www.bagriders.com/fittings/flow-controls.html
what would u recommend for a 2012 mustang gt
1/4" air line will work perfect for your mustang!
@@bagridersthanks !
Would there be any benefit to running 1/2" airlines to the front only? Would it help drop any quicker? I know the fittings and line are compatible, but is it worth it?
1/2" Air Line would be a little too quick. What we do sell are fittings called flow controls! The flow controls help slow down the air flow so the car can air out evenly.
@@bagriders wish you made a vid with 1/2"
@@salimsopari The 1/2" air line would air out even faster than the 3/8!
How many psi should I run in my Lexus Rc 300???
If using an Air Lift Performance suspension the recommended air pressure is 60-75 PSI Front & 100-120PSI Rear.
If I change my 1/4 to 3/8 would I need to change fittings?
Yes you would need to change air line size and fitting size.
@@bagriders and the manifold?
@@Robin-kg1yv Ideally you would want to change the manifold but changing the fittings and air line is a more cost effective options.
Do they lift at the same rates
No the 3/8" lifts faster.
@@bagriders only as fast as your compressor!
@@keithv4452 Compressors only have to do with your tank fill time. The air line size determines how quickly your bags will raise and lower.
Wanna see my 1/2 air setup haha
Sure! Send us the video!
i want to see it
Is 3/8 noticeably louder?
Yes, it's slightly louder! Having no air line off the manifold will give you loudest result.
Doesn't matter in the slightest. Get whatever fittings, lines and valves are cheapest.
Line size matters! This will help create a smoother air out and up to be able to achieve your desired ride height.
@@bagriders I am in no hurry whatsoever to collect "stance points". Hahaha
1/4 inch is more for the fender on lip look
Air line size isn't for a specific fitment, its based on what weight your car is and how fast you want it to air up or down.
@@bagriders I knew that but most guys running fender on lip fitment usually go with 1/4 inch because of the air out speed
@@Eli_Eli_ Don't forget you can also run dump mufflers to help with air out speed too!
Doesnt even make sense. Air line size only changes air out speed. Has nothing to do with fender on lip fitment. LMFAO. Think about what your saying lol. All your doing is changing an air line. 3/8 air line is bigger which allows you to bleed out air faster. changes nothing about suspension travel or fitment@@Eli_Eli_
@@derekd7148I guess what he means is 1/4 airline would drop slower on the lip than 3/8 so it doesn't fxckup the fender
So 1/4 in is for posers and 3/8 in for the reals, got ya
Truly just comes down to personal preference!
1/2 inch is for the OGs
