Just center your axle dude.... then we’ll go from there. Springs are gonna arc some when compressed because the axle is being pushed out as it’s compressing, which then makes the top and bottom of the spring misaligned. That pic is wonky because not only is top and bottom misaligned it’s also to far to one side. Here’s pic of my spring drooped and compressed, there’s an arc in both scenarios.......

Well like everyone said you need to center the axle. The Mopar kits are incomplete and you'll see that from every jl owner who has one. Springs, shocks and lower arms are not enough. They should also include atleast a front TB for correction and I second the RK perches. Even had to use them on my MC lift.

RK is one of the few companies to make a quality lift for the diesel. All others use spacers. Evo doesn't but people have come planned the springs sag within 6 months.

Hopefully it's as simple as that if not I would get them to refund the lift and put stock back on and go buy a better quality lift

lower control arms are not needed for anything lower then 3.5 inches. I ran an evo 2.5 kit with nothing but track bars and it ran and rode amazing. Didn’t ever sag from what I could tell either.

If you disconnect the front track bar and jack the jeep off the ground the springs will center the axle, then you can check the clearances of the springs and the frame to know if that will fix your problem.

it might not make as much of a difference on a Rubi that starts out a little higher, but the MPP Diesel-specific lift took my Willys diesel up well over 4" in front (and nearly 4" in the rear).

adjustable track bars and relocation brackets were absolutely necessary to get things where they belong, even after putting a winch on it brought the front back down to 3.8"

Sorry for your issues. I also have a 2021 JLUR Ecodiesel. I installed 35s without making any other modifications and everything is good. It seems like the Mopar diesel lift leaves folks with some issues that did not exist prior to the install.

Lots of old Jeeps. JLURD ordered 5/7.
The upper spring isolator (factory OEM part) is wedge shaped to bow the spring out towards the tire. It has two nubs on top to properly orient it to the two holes I'm pointing to with my pinky and index fingers....

If the isolators are properly installed, you will see/feel the nubs in these holes (will need to push in the inner fender liner about an inch to see/feel the holes).

Right, but your S-curve is in the opposite direction of mine.
Your springs are not seated properly
They are. I have verified this many times.
The Mopar kits are incomplete and you'll see that from every jl owner who has one. Springs, shocks and lower arms are not enough. They should also include atleast a front TB for correction and I second the RK perches.
Agree, but the kit should still be functional (no parts interfering when fully articulated), right?
If you disconnect the front track bar and jack the jeep off the ground the springs will center the axle, then you can check the clearances of the springs and the frame to know if that will fix your problem.
Good idea. The dealer won’t do it, but I may use this if forced to fix on my own.

I ran with the 35s and no lift for a few weeks. It’s fine, but the suspension could be better with the larger unsprung mass, and it will rub off road.

Right. This has been verified.

They are installed correctly. It’s the springs themselves. Mopar acknowledges they have a problem with springs. We’re trying the third driver spring now.

If anyone is out there with the diesel Mopar lift, no aftermarket upgrades, and has tested the articulation, please let us know the results!

Why not just get the money back from the mopar kit and have a far better aftermarket kit done?

Update: The dealer installed the third driver front spring, drove up on rocks, and both driver and passenger springs hit the frame!

A lift expert at another dealer informed my dealer that the Mopar installation instructions are wrong and have the spring part numbers reversed! The ‘rule’ is the higher number part goes on the side of the fuel tank. Well on the diesel the fuel tank is on the opposite side.

So, they’re switching the springs now. We will see…
