JLU 3.5' lift kit advice sought

Can you share your experiences or advice on available 3.5-4 inch lift kits?
Am driving a 2018 JLU sport plus with 35 STT Pro, mostly for dune bashing and not rock crawling.
I can only see Metal Cloack, EVO and Skyjacker have kits available.
I ran 3.5 inch on my JKU from teraflex with 33 tires but I don't think teraflex have released their kit yet.
Would welcome your views on any of these brands, Thanks !

Teraflex has the ST3 kit out:

This is the kit I'm leaning towards for our JLUR

JKS has a 3.5"

Check out JKS they have a 2.5" and a 3.5" with standard and "heavy duty" springs, available fox shocks, seems like a pretty complete kit and it comes with an adjustable track bar...reasonable prices...

Thanks.
My concern with the teraflex kit is that adjustable control arms are not included nor are adjustable track bars. Surely these are needed to reset the geometry....

Mopar kits are excellent choices for the JL. Check them out. Re: The Teraflex ST3 Kit, you will not need adjustable arms or track bars with it.

Some TF kits come with longer non adjustable control arms which in my opinion are by far the best. NO margin for alignment error when the arms are solid..

mopar has had issues with their coil bending and the "fix" was a sliver of plastic that crushes quickly.

I have the Mopar 2" lift on my Jeep and love the look, the ride and the ease of install.

It was not that the coil was bending, it was that hard durable plastic resting plate was formed incorrectly on the drivers side and it was causing the coil spring to sit unevenly. This was addressed by an engineering fix from Mopar last May and all new coil spring plates were replaced in all lift kits as of May of last year.

I had a kit that was assembled prior to May of last year, Mopar quickly and efficiently replaced the part prior to my installation and I have not had the issue.

So, the fact is that there was a problem. It was not the coil spring. Mopar released a fix that corrected the issue. The Mopar lift is a perfectly fine lift.

That being said, there are many great lift kits out there other than Mopar. The real question is what is the purpose of the lift you want? What size tires do you want to run? What are your offroad plans? All of these questions factor into what size (and brand) lift kit you want.

Rock Krawler has a whole lineup of 3.5" lifts for your JLU. Let me know if you want pricing. Shoot me a PM. I would say to go with the package deal here.

Let me know if I can help at all with info or pricing.

Before doing a 3 1/2 inch lift, find out if there are any warranty issues. If that matters to you.

Generally speaking, it won't. Have you Checked out Rancho? They have some lift kit packages with arms and shocks for around $1200.

Exactly. I also see drop brackets no way.

pretty sure we are going with a 2.5" Xfactor Rock Krawler lift on the JLU, love the same kit I have on the JK. I love having full adjust-ability everywhere I may need it

I actually pulled the trigger on the st3 3.5" Teraflex kit. I'm not sure if I'm gonna go long arm or short arm and I decided that even with drop brackets in front there only temporary.

Noteda couple anti-drop bracket comments. From experience I’ll tell you drop brackets are not to be dismissed. The tiny bit of clearance sacrificed is more than made up for in driveline angularity, caster, ride quality and stability. You’ll essentially get nearly the same positives of a front long arm without the cost and hassle. And being a long arm user, you ain’t seen clearance issues! JMHO, of course.

It does matter : - ) ...and yes I believe warranty might well become void.....Hence I am keen to select the best possible set up so to minimise any negative impact over time on the drive train.

I had a 2013 JKUR I bought new. Engine started burni g excessive oil. Took it in to the dealership, after testing they determined that the engine had gone bad and recommended a new engine. Chrysler approved it. My jeep had the old 5 yr 100k warranty. They replaced engine under warranty. At time of failure it had 81k on it. I was running a coilover, 37s but no engine mods. As far as I know, a guy litigated againt Chrysler and won because of this, it's on the internet. General rule of thumb, if you mod it its not covered. That's why I'll never run a cold air.

This is the lift i will be going with. I had the 3.5 x-factor w/Fox shocks on my JKUR and loved it. The same thing is going on my JLUR.

I liked my x factor on my JKUR.
But the springs are on the harsh side. Right now I'm running a Teraflex ST4 and it rides like a nice sedan.... So smooth....

JLU 3.5' lift kit advice sought

I have the X-Factor 3.5 and I really like it. It depends on what a person is accustomed to. My other ride, Audi S4 sedan, is so harsh that I need to wear a tooth guard. But, it handles like a wet dream.

Have you tried Rancho or Teraflex springs? Both ride very nice and better than RKs springs I can tell you that,

No, I just recently went up an inch and went RK springs as I figured they would play well with the X-Factor stuff that I already had. When I had the RK 2.5 springs it was a pretty optimal ride for me. Then I went 3.5 but also added a bunch of stuff, including 37s and it was much stiffer. It seems to point to the 3.5 springs being stiffer than the 2.5. Its fine the majority of the time and happy with the off roading. On the highway infrequently a stretch of road has undulations at just the right spacing that seems to be in tune with the suspension. Its a little weird, but doesnt upset the steering.

That was my JK experience with there springs. The rest of the kit was great.

I have the RK X factor stage 2 kit on my JKU RHR, when it’s time to replace my JKU, I will get another RK suspension system.

Zero complaints with the ride except a few weeks ago when the high temp was 0 F, low was -4 F.... almost comical how the cold weather made the external resivoir shocks not work. Took probably 20 miles for the shocks to warm up a bit.

Sometimes I wonder if when people complain about ride on their suspension system (from any manufacturer) I wonder how many times the shocks aren’t ideally valued for the springs resulting in the ride.

From what Ive heard Id say the MC game changer is one of the best 3.5 inch kits. I love their stuff. I have the 2.5 GC on the way in the mail.

Your ride comes from your coils. Shocks smooth out the bumps. There's lots of info on this...that being said, the only thing that matters is if you like it.

Yes shocks help smooth out bumps, help with rebound etc..... if the shocks arent or cant smooth those bumps out a rough ride can be and often times is the result.

Changing shocks can drastically alter the ride characteristics of any vehicle.

But yes, what matters is the nut behind the wheel, if he/she likes it
