Yessir. You’re only netting 1-1.5” of lift with the Rubi springs. You don’t even need to loosen them for a 3.5” lift if you don’t want to. Track bar is fine, brake lines are fine too. If you’re going with a full lift then I could walk you thru what I do for the brake lines but for what you’re doing it’s not needed. Track bar is the same between the jeeps too.

Awesome! Thank You!

Brett, a question.

I've got the front done with no issues. Doing the rear. I was double checking which spring goes on which side and I'm seeing conflicting information

The rear springs I have are 68253591AA (Left) and 68253590AA (Right). Do I have those spring positions correct? Like I said I'm seeing it both ways on the interweb..

Thanks!

I have all that stuff in the shop and I’m not there today. I’d recommend calling the dealer and talking to the parts Dept. They should be able to tell you which is which

Sorry, I can’t remember off the top of my head

@cb4017 , when I pulled the springs off prior to putting the lift on, the passenger side springs were taller (both F&R), noticeably. @rustyshakelford is right, the dealership should be able to confirm as well if you'd like.

BTW, Bret, thank you for all the useful information you've provided on many threads.

Higher spring part number goes on the passenger side.

Also like ghostdiver said, the taller spring (which should be the higher part number) goes on the passenger side.

That's the way I installed them. 3591AA on the passenger side and 3590AA on the driver's side. The 3591AA was the taller spring. I figured if it was wrong, swapping the rear springs is not too tough a job.

BTW, I ended up with 1.125" lift on the front and a little over 2" on the back.

Thanks everyone.

Yes, the front LCAs. 190 ft-lb for both ends. UCAs are 80 ft-lbs. Rear LCAs are 90 ft-lb at both ends. Rear UCAs are 95 at the axle and 120 at the frame.
thanks for the info. :fist bump:

i wonder if that 190ft lbs is a misprint. i have spoken with some people who say that 190ft lbs seems really high. ive looked at some of the other aftermarket LCA kits (including a TF kit in this thread) and they have MUCH lower torque value for the front LCA bolts. just want to double check. ive over torqued and snapped a suspension bolt before :facepalm:

i'm gunna bump this. 190 ftlbs seems excessive.

https://www.jlwranglerforums.com/fo...for-jeep-jl-wrangler.17791/page-2#post-518105

in this post they're listed as 103ftlbs plus 50 degrees. i wonder if the Nm and ftlbs spec are getting confused.
Based on my experience when installing my Mopar LCAs I'd say they were every bit of 190 ft lbs when removing them. When I installed the new ones my torque wrench only goes to 150 ft. lbs I maxed that out and used my 2ft breaker bar to go another 45 degrees. I know it's tighter than the 103 +50degrees but seems much closer to what the bolts were from the factory.

I just replaced mine and I can tell you for sure the factory had them torqued above 200. When I installed new ones I torqued to 190.
How did you tighten them to 190. Big pipe over torque wrench handle ?

2ft breaker bar w/ front tires on ramps, this will allow room to get leverage. I used my 150 ft lb torque wrench maxed out and then another 45 degree w/ the breaker bar, was easy w/ that.

They don’t need to be touched. Remove bottom bolts from sway bars, remove shocks, raise vehicle up from frame, slide sport coils out and Rubi coils in. Lower down enough to install Rubi shocks, bolt sway bars back. We do these all the time in the shop. Maybe 2 hrs f/r. Don’t even have to remove tires but it makes it easier.

I’m looking at having my local Jeep shop install these mopar LCA’s, they did a rubicon spring swap last year in about 45 minutes. Also just had the new steel steering box installed TBS at the dealer, so I’m thinking there should be some serious steering improvements. Going from the aluminum box to the new steel one was noticeably a huge benefit. Do you recommend installing bigger bump stops inside the coils since I might also use .75 coil spacers once bigger 285/75/17 tires are on?
