XJ Rock-Link Long Arm Install from Iron Rock Off Road
Вставка
- Опубліковано 4 лют 2018
- The paramount suspension upgrade for your XJ is a long arm system. Iron Rock Off Road's ROCK-LINK 3 link long arm system offers unrivaled performance, giving your Jeep both the capability and ride quality improvements that you have been looking for. This ROCK-LINK long arm upgrade is built for strength, clearance, adjustability, flexibility, and ease of install.
STRENGTH: Our subframe is constructed with 1/4" steel and our lower arms are even thicker at 2"x5/16" wall D.O.M. tubing. That's thicker than 1/4" wall!
CLEARANCE: We tuck our subframe up as tight as possible to gain you the critical extra clearance to keep your Jeep low and your belly high! The lower arm connections at the chassis are as high as possible with still being able to install a bolt through them. The control arms have an inboard bend to clear your tires, so you can steer lock to lock without rubbing on them.
ADJUSTABILITY: All the arms have tons of adjustment built in for your stock situation to your stretched crawler.
FLEXIBILITY: Yes, of course we are talking about articulation, and the ROCK-LINK delivers plenty! But we are also talking about flexibility to install other axle combinations with ease. Use this kit with your stock Dana 30 for now, and then bolt in a Dana 44 or Dana 60 down the road!
EASE OF INSTALL: No welding, no complicated setup or templates. All you need is a drill, a floor jack, some jack stands and some hand tools. This is a BOLT-IN kit, although if your preferred method of installation is welding, you can do that!

Can you please make a video for the rear 4 link coil over upgrade. Thanks
Awesome! I wish every company took the time to make in depth videos like this for their products. Made the install a breeze!
@jedgraves8399 Thank you!
Is that a Dana 35 rear and im really liking the look of that 4” with 32” inch tires on stock rims with long arms front & rear !!! Great setup right there…. You guys rock 🤘🏽
Just got done installing this kit took me a day and a half super easy to install measured everything twice and it all came out great ride from short arms is truly night and day drives great and better handling at least for me awesome product no complaints so far hardest messiest job was cutting the lower control arm brackets but all in all it's done
This kit was really easy to install. The instructions are clear and easy to read. I've been running it since November and have no complaints so far.
Hope to see the rear 4 link install soon as that's next on my jeep list.
how is the on road handling?
It's much smoother and more stable compared to my old JKS short arms. I don't feel like I need to slow down as much for long sweeping turns or big bumps
Great video-thanks. Just got mine all hooked up in about a day total. Only problem was that once everything was installed I needed to adjust the caster. I had torqued the flex joint on the upper arm before install and didn’t want to take it all down to re-do the length. I found that I could just remove the axle end bolt from the upper control arm and rotate the long section to adjust. It was tight and I did need to remove the pinch bolt so it would clear the frame as I spun it around. Good thing I had left all the nuts and bolts loose. I will torque everything tomorrow and be back on the road. Thanks guys. Detailed instructions are so helpful with everything I’ve bought from you.
@floyddparsons Great tip! Thank you!
Looks like the best lift for the money.I will be getting this kit for this years winter project.Cant wait!!!!
Ordered mine on Monday fit my 01 xj limited. Can’t wait for this fall/winters rides to come🤙🏼
Very nice install video! This kit has been on my radar for some time and this video makes me want one even more!! Gotta save some coin!!!
Nicely done Jason! IRO is as good as it gets!
This kit is QUALITY. I chose it because of the geometry works the best. The hardest part is cutting the short arm front mounts off of your Jeep.
Thank you for the feedback!
the only thing i wish ya'll would include in the kit is new rear leaf bolts, mine were wasted and the stores around me didn't have any of the same bolts. such an amazing kit though
We do have a leaf spring bolt kit!
Thank you Jason. I appreciate your help
sincerely

@javierguajardo1760 Glad we could help!
Can you do a video on the 01 XJ 6.5" Critical Path Long Arm Lift Kit
Any chance we can have a video on installing your rear 4 link leaf spring delete kit? Great video by the way. Made setting up my rock link long arm setup way easier
@seanmccarthy8404 Stay tuned to our XJ build series we will be installing that kit soon!
Trying to figure out why I had to stretch my rear with your 4link kit . My lower control arms are currently sitting at 45” . Any shorter and the springs won’t line up with the upper spring cross member . . Any thoughts?? I also had to lengthen my drive shaft bc of this
Hi guys I just purchased a XJ ROCK-LINK Front And Rear Long Arm Upgrade and I forgot to ask before but I’m installing it on dana 44 from a grand wagonner tho I order for a jk dana 44 cause that was the closest option and I’m wondering if it would be any problem to weld the truss or any other problem whatsoever that you guys would know??? Thanks
Will this kit install the same for a '88 MJ?
What lift size is on that xj ?
When you torqued the carriage bolts holding the crossmember up how were you able yo get a torque wrench and socket up there im having trouble finding room and dont want to have to remove the exhaust
you may need a swivel socket, however these are not critical in terms of hitting an exact torque. Our torque number should be followed whenever possible, but if you're unable to get access, find one you can get access to, and after you torque it, put a wrench on it to "feel" the torque, and use that same wrench to tighten the nut down the same.
are you supposed to line the half/hole in the races up with the zerk fitting hole in the housing?
No need for that, there is a radius on the outside edge of the races to allow grease to travel around the joint to the half holes.
What is the difference between the ride or capability between the Rock-link and the Critical Path products?
Eric Nutter not as much as you would think! Of course there are differences, but performance and ride are very similar.
I have a question... I had and xj with your older y link setup, now i have a zj. Could i buy a new cross member for the zj and put the y link arms from xj on it
It will bolt in, however with the Critical Path system, the XJ and ZJ had different length upper links to allow proper caster adjustment for each. The best way to do this would be to take the high pinion axle from the XJ and use that in the ZJ as well. And yes, the crossmember would be different as well.
Dude installed one of these today on my 99 XJ. It was a bitch getting the cross membrane to line up with the Trans mount and then line up with the subframe outers. I had to kick the jack holding the t case towards the passenger side to notch the t case and trans over about a third of an inch to get everything to line up. It was scary...Also no idea how you’re suppose to Torque those lower control arms to spec Bc there’s no clearance to get a wrench and socket in there. Would love to see how you torque everything because it’s certainly a hell of a time.
Glad you got everything put together! Just use a short extension on your ratchet. Easy peasy.
What size are the tires and wheels? THANX For The GREAT Videos...
These are some factory 15" wheels with 32" tires.
How do i know when im done with this install that my lower and upper control arms are adjusted to the correct length?
Hey Dylan, the couple things you need to be aware of with your adjustments are: is your alignment (specifically caster) adjusted to your desired setting?, and is the length set to match the combination of lift, tire size, and fender trimming, so as to minimize or eliminate tire rubbing?
I installed this kit on my xj and it made a huge difference, but my exhaust contacts my passenger control arm and everything is centered and installed correctly. Do I have to modify my exhaust?
@dansattler882 Thanks for the feedback! We have not seen any need to modify the exhaust if you are running 3 inches of lift or more. We would be happy to help you figure it out. Send us some pictures in an email to tech@ironrockoffroad.com.
Will this kit work with frame stiffners?
What is the difference between 4 link and 3 link?
Yes, this kit WILL work with frame stiffeners. In fact, Iron Rock stiffeners contain all the holes needed, to make installation a breeze. The 4 link is our rear suspension. This video is showing the front suspension (3 link)
What lift height are you running? Also do you have an install video of the rear coil conversion install?
4 inch on this Jeep. I don't have a video on the coil conversion yet, sorry.
@@IronRockOffRoad
What size tire on that gray 01 XJ
should i install my frame stiffners before the lift or should it be done after?
@TheBackpackingSailor We always recommend doing the center section frame stiffeners before a long arm install because the transmission crossmember will need to be removed to install the stiffeners. When you finish the stiffeners, you can install the new long arm crossmember and it will save you some labor time.
Check out our XJ build series. We started with an empty XJ shell, started with full frame stiffeners, then moved onto suspension.

Do i need to remove the passenger side upper control arm bracket
No, that bracket can stay, as it is eliminated from use, and does not interfere with anything in the Rock-Link system.
DO YOU HAVE ANY ON THE INSTALL FOR THE REAR FOUR LINK INSTALL ON THE XJ?
We don't have a 4 link video for the XJ, sorry!
Does this not work on an 01 with the centered transmission mount??
you can use this with a 01, but will need to convert to the older trans mount such as: www.ironrockoffroad.com/product/xj-transmission-mount-oem-replacement-steel-rubber-black-jeep-suv.html
Awesome!!!
👍
Very nice
When i remove the crossmember to install the new one do i need to jack up the transmission and transfer case to support them?
Yes, supporting the trans with a jack helps with alignment of the new subframe assembly!
@@IronRockOffRoad ok thank you. If i am installing the iron rock full lift is it better to do everything with the 3 link system first and then install the new springs shocks and track bar?
@@dylanreynolds4899 I would do the 3 link component install first.
How is this 3 link as strong as 4 link?
looking at it i see the upper 10mm bolt as a weak link
purchase link?

Is there an install video for the bolt in xj 4 link kit?
@85Thatguy Coming Soon!
LOL I love how you guys dont show JUST how long it takes to cut the lower arm mounts off flush... Better plan for 1-2 hours on a ZJ jeep with the same setup.
also didnt note that the right lower arm wont clear the exhaust pipe. lol
@MarcusEhrhardt If we showed how long it takes it would be a VERY long video!
@crashtestperformance3596 Not sure what you mean.
Where in hell an i supposed to find a 9/64ths allen head? I didnt even know the made allen heads in 32nds
@user-md2kd5lf5j He might have misspoken in the video.
Hey man we all know one click and it's snug, don't get lazy on us.
ok, lol
@@IronRockOffRoad The rock link is pretty sick, saving up it.
