At this point it seems questionable as to whether or not this badge belongs on my Jeep:
E7BA06C5-FFF7-4B05-BA2C-171F0F524EA6.jpeg

I have a 2021 JLUR Ecodiesel. I wanted a functional lift for better breakover angle and to fit 35s. I have had many many problems with my previous JL and wanted to add a lift without any warranty compromises. After terrible experiences at one dealer, I found a great dealer that I’ve been working with for a while now. I had them install the Mopar Lift Kit. They installed it properly. I know because I’ve done one myself on my previous JL and verified the install (spring seat in perch, rubber nubs at the top, spring part numbers at each wheel, etc.).

The first issue was misshapen passenger and driver springs in the front:
85DCF8E4-B2B7-4B99-B164-49808B9F66FE.jpeg

The passenger spring rubbed the frame when the tire was raised on a small ramp:
71B44F29-6ED9-4058-9D95-19F2401496AA.jpeg

After confirming a proper install, Mopar advised the dealer to replace both springs. The new passenger spring is better:
AE81C00C-693A-48CF-A651-3828B8A662CC.jpeg

But, it’s still close to rubbing with climbing a small rock:
2D7C3E98-D977-45D0-9007-5A1ECEEDCFBF.jpeg

The driver spring is the same as the original, S-shaped.

Now Mopar says order another driver spring.

Ok, so I’ve asked the dealer to test at full articulation as well. I’m worried about that passenger spring when it compresses. I’m also worried that the third driver spring will be the same as the other two.

Is there a path to a working lifted suspension that doesn’t use third party parts?

Is there anyone out there with a working Mopar Lift (diesel or not) that doesn’t have S-shaped springs that hit the frame?

Has anyone tested this lift at full articulation? Do you have photos of what these springs are supposed to look like??

Any help would be greatly appreciated.

Check to make sure your axle is centered. Side to side. You may need an adjustable track bar, also get some RK spring perches

My hunch is that it's because you have a diesel which is much heavier than the Mopar lift kit was designed for. People who were initially adding this kit to the 4xe's were seeing the same problem, bowed springs, so Mopar designed one specifically for the added weight. Wonder if you would do better to get the 4xe 2" lift kit instead?

Seen this on my jeep after replacement springs. You will need to check the up spring pad. I had to rotate my 180 degrees when I changed out mine to the rock krawler springs and correction pads.

An adjustable trackbar would help with the running and was my first thought. However the springs shouldn’t bend like that.

Thanks for the suggestions. Understand those RK perches are a good idea. It is a diesel specific kit, so the springs should handle the extra weight. Also, I know the axle is off center and this could be fixed with the adjustable trackbar. But, the Mopar Kit should at least be functional without these, true?

Will the trackbar fix the spring shape and frame clearance? Anyone have before and after experience with these?

Should I expect the dealer to use aftermarket parts to fix for free if that’s what it takes?

And why after four years of the JL can JPP not get springs right???

The track bars should at bare minimum fix the clearance of the spring where it touches the frame. Something to consider is that all springs settle over time. My king coil overs settled 2-3 inches after a year or two of use. So it is possible that those bends could work themselves out. Do you hear any slapping or weird noises when driving it over things? Does it bounce around a lot?

Drove it home and started testing with my small ramp. Didn’t get very far with the spring hitting the frame at about half articulation.

Is it only one side hitting the frame? If the other side has a lot of space then a track bar would prolly fix your problem. Don’t forget if you do the front, the backs gonna need them too.

Is your axle centered, you might need adjustable track bars. It looks like your axle is being pushed hard over to the driver side. I only added 1.5" spacers to my Ecodiesel and I needed track bars to re-center my axles. Edit: Just noticed that a couple other have mentioned track bars.

Got it - trackbars. This will help the passenger spring for sure. The drivers is close to hitting now though, so I’m not sure about that.

But, is it possible to drive this Jeep away from the DEALER with the Mopar stuff working (able to fully articulate without hitting)???

I think I can fix it myself, but given my past experiences I would like to avoid working on it until the warranty is up. If I have to I will, but it’s truly unbelievable that the factory upgrades don’t work! Maybe it’s the rarity of the diesel.

You had me at . . . ." I know the axle is off center . . . . ." Might want to start there.

Any amount of lift will shift the axle since the trackbar length doesn’t change. The point is the kit should ‘work’ without a new trackbar even though the axle is slightly off center. There is no Mopar adjustable trackbar.
