There's quite a bit of discussion on the JL forum about adding these to stock Rubicon trims and those that have swapped out to Rubicon springs to correct the caster angle, but not quite as much here that I've seen, so I figured I would add to the information and pass on my experience to those that maybe have not seen this discussion or are on the fence about doing the swap.

Background:
I swapped out my stock Overland springs and shocks to Rubicon take offs not long after I purchased my JT. I liked the slightly taller ride height and added clearance for my 275/70R18 tires, but I was never a fan of the way it rode. I wasn't sure if it was the shocks, springs, or the combination of both. I've been driving around this way for about a year and a half now all the while hating the ride and doing some research, I finally got fed up enough and figured it was most likely the shocks and pulled the trigger on some new Eibach Pro-truck shocks. (My discussion on that here https://www.jeepgladiatorforum.com/forum/threads/anyone-running-eibach-shocks-or-springs.67192/) Which I really like a lot by the way compared to the Rubi Fox shocks.

While researching into improving the ride, I also came across some folks who had similar complaints over on the JL forum who were swapping over the LCAs from the Mopar 2" lift to their stock Rubis and those with Rubi takeoffs to very satisfying results. Since the price was so affordable, I also ordered a set of these that arrived this weekend. Having just swapped out the shocks on Thursday and I was already happy with the difference the shocks alone made, I wasn't sure how much of difference the LCAs would provide. So while I had some time this morning, I crawled under the Jeep and swapped these out. All I can say is, WOW! I'm really blown away the difference these 1/4" longer LCAs make to the ride along with the new shocks. It improved bumps, steering, and handling at high and low speeds. All in all I personally think it's now riding better than it did with the stock Overland setup I had before.

So to anyone who has a stock Rubicon, Mojave, or has Rubi/Mojave take off springs I whole heartedly recommend this swap. It's really impressive how much better the ride and handling is and for an extremely inexpensive modification. I picked up my set of LCAs for $72 total with shipping from BAM Wholesale Parts. It was about a 30 minute swap for me in my driveway, no jacks, and nothing other than some hand tools and my cordless impact. The hardest part is getting the bolts retorqued to 190 ft lbs when you're done. (I followed some advice from the JL forum about torqueing to 103lbs and than another 135 degrees after with my breaker bar and a length of pipe) I've read this took some a couple hours to complete without the use of an impact to break away the bolts so do yourself a favor and borrow one if you don't have one and save yourself the added effort. I had both LCAs dropped in less than a couple minutes with the use of the impact. Otherwise I used my 21mm sockets, 1/2" torque bar, extensions, breaker bar, and a 24mm box wrench, (although a 15/16 SAE supposedly fits better on the nuts, but I didn't have SAE in that size). I'm sorry I didn't take any photos because it went together so quickly and easily I completely forgot to document.

Glad to hear it improved your ride. I'm planning to level out my '23 JTSS and have heard that adding these LCA improved the ride even with the 1.5" leveling kit.

Reviving this thread... I'm going to be adding a 1" Spacer and going up to 34" tires on my Gladiator. Would these slightly longer control arms (68322798AA) benefit my set up although it will have stock Diesel Sport S springs?

I was just thinking since I'll be loosening the control arms anyway for the 1" spacer, I might as well upgrade the arms. My steering is currently fine, as it currently sits stock with 31.5" tires, but I can tell it has loosened up some since the truck has broken in.

Necro bumping this as it came across my search on the subject. Just did a Mojave axle swap into my Sport that also has a Rubicon diesel spring suspension and shocks. Rides overall ok but just does not seem as planted as it was stock. Got two arms on order and going to give it a whirl.

I'm also going to bump the thread instead of opening a new one.

I have a newly purchased Mojave that I plan on leaving essentially stock. On the highway it doesn't seem to be quite as stable as my 21 Sport was, before or after the Mopar lift.

Just so happens I have a set of Mopar Performance LCAs in the garage from back when I was messing with my 21 Sport. I didn't use them because I ended up buying a complete Mopar 2" lift, which had them included.

I was wondering if it would be worth it to put the performance LCAs under my stock Mojave to increase the caster a little. Looks like I have my answer.

I went through with it and have no regrets.

I have a mostly complete stock Rubicon diesel takeoff kit if someone is looking. Only has ~20k miles on it, missing the front sway bar links, they didn't want to come quietly. Have the springs, Fox shocks, factory LCAs, rear sway bar links. Anyone interested, message me.

Just remember to loosen all front control arms and track bar and retighten with the weight of the vehicle on them if you only did front springs . If you did rear too than do the same to them if using OE type bushings . It will effect ride
