- The factory suspension on our 2021 Jeep Wrangler Rubicon 392 left plenty to be desired. While there are no shortage of suspension options available for the JL platform, in this video we will be review the JKS 2.5 Inch lift that we installed on our Jeep.

Those shocks are officially a must buy for my rubicon!
Very thorough and informative suspension, wheel and tire review. And you adjusting the exhaust tips was a plus.
Your videos have become extremely helpful in showing setups like wheel size, tire size, backspacing, etc. with XR 392s. The great shots of how the tire sits under the fender flare and how the lift looks has been great to see. You have helped me a lot to decide on setup of my XR 392. Thank you
Love my Fox 2.5’s. ❤👍🏻🇺🇸
You are a very nitpick man to be a jeep fan but I dig it. The only two things you said that I love is the squat in the rear end when you floor it and how the tires wanna spin a lot in 2WD.
Boa noite congrats carros vai amén bom trabalho
👍
I've been trying to figure out what to do with my 392 and like the Fox 2.5's as well or maybe 3.0's. Either way it seems you've proven as nice as the set up is you tested, 2 1/2 lift isn't enough with 37's or 38's offroad. Looking for the happy medium without being too high so I can fit it in my average sized garage.
You can run 37's with this setup. You just have to make sure you get a wheel with around 4.75 inches of backspacing. Even with the 38's under the Jeep, it fits under my 7ft garage door with plenty of room to spare.
I'm no expert, but I'd be willing to bet that the wheels having 25mm of positive offset is much more of a factor than the backspacing. Each wheel is sucked in towards the center of the Jeep by nearly and inch. A 0, -6, or even a -12 offset wheel would almost certainly solve your rubbing problem.
They are both somewhat interchangeable. On the truck/SUV end, backspacing is the more common reference. Offset has generally been more car related, but you are saying the same thing essentially. As I mention in the video, 4.75 inches of backspacing (0 offset equivalent) is the right choice for this build. I just wanted to try the wheels I had first.
I currently have a 2.5” lift under my rubicon with Fox 2.0 shocks. I’m looking for a better shock because I feel to much of the road and find myself avoiding as much of the road imperfections as possible. Can you give me your feedback regarding the 2.5’s. Thanks
I had the 2.5's with DSC adjusters on my JK a few years ago and obviously now this Jeep. The DSC adjuster is well worth it if you are trying to dial in the best ride. I will caution you that if you feel a lot of road imperfections it could be due to your spring rate actually being too stiff and not allowing the suspension to properly cycle. A quick way to test for this is to clean your shock shaft and wrap a zip tie around the shaft at the base of the shock body at ride height. Go drive your normal commute and see how much the shock is actually traveling. The 2.5s are well worth the money, but you need to make sure you pair them with a good spring or you won't be able to take full advantage of the upgrade. Thankfully, swapping springs is much cheaper than swapping shocks.
Nice! Do you know if the transfer case in the 392 the same as the Rubicon 4Xe? Since it has 4WD High Auto! Thanks.
That is correct. It has the same 3022 transfer case.
@@DrivingLine I thought so, thank you! In the 4Xe however, you are able to keep it in 2WD only. What do advise when off road then? 4WD part time (which actually means full time when engaged) or 4WD Auto?
@@exoplanetnomad I would avoid using 4WD Auto. That is when the clutch pack is "active" Placing it in 4 Hi or 4 Low "locks" the pack together.
Any maverick update?
I ended up selling it to a good friend that had been looking for one. My new one is scheduled to be built at the end of the month. It's an XL hybrid as well.
Did you like the 38" tires better than the 37" tires?
For this Jeep, I like the 37s better. The footprint of that 38 just makes the steering really heavy off-road. This is mostly due I think to how heavy that 392 engine is. Under my Gladiator, the 38s don’t seem as difficult to turn. On road, there’s not a huge difference. The Jeep definitely feels a little faster and the steering is a little lighter with 37’s.
You rubbing standard or hd springs?
There wasn’t an option for standard or HD when I ordered the kit. I would assume these are HD just based on the weight of the engine.
What steering upgrade do you suggest for a 392 with 40s?
My steering is pretty heavy off-road with the 38s. Anything larger and I would probably just do hydro-assist. PSC makes a bolt on kit for the 392 now.
@@DrivingLine Thanks for the info
