Went to my dealership today and while I was there, measured at least 4 JLUR 4xe w/ stock bumpers and tires (ko2). Noticed an interesting trend; all the fronts measured 1/2 inch taller than the rears. They were consistently 24.5" (front) and 24" (rear) - measured to the same spot on the fender. This makes sense due to the placement of the battery on the 4xe. So this begs the question of whether it makes sense to swap the spacers of the spacer lift kits and put the taller spacer in the rear....especially for overlanders and car campers who will mostly be adding weight to the rear of the Jeep. Where might I be going wrong with this line of thought?
That's expected. The rear is actually higher, you just can't compare the front to rear because the Rubicon has raised front fenders by about 1".

So with those measurements, is it safe to conclude that the rake is higher by 1/2 inch on the rear (at stock)? This may be a dumb question; what then, is the proper way to measure for "leveling" the vehicle?

Yes, 1/2 - 3/4" is about what I an seeing. My Sahara as just under 1" (just picked up).

I don't know if there is a standard way, but I'd say run a straight edge along the lower window line and measure up to that? Maybe "extend out" from the running boards and use that as the parallel?

One thing I've taken note of is that with the 4xe, there seems to be no immediately available way to lower/re-route the rear e-brake lines. The inside floor extends way down in front of the crossmember that you normally re-route the lines under, there's zero room to run the lines the way most non-4xe lift kits require. In fact, the body mounted e-brake line bracket up under there is a new "wire hanger" bracket. So chalk that up as one change that will require something different when going 2"+ in the rear (and factor in the already 1" from the factory...). I think I'll be find putting my 1" spacer in there, I'm not going to be going major off-roading, but it's something that most lift kits will need to change how they address with the 4xe.

Thanks for the input and added info!! Since this really is a temporary lift for me (until the actual off-road needs define itself - using this for a long term overland rig), I will probably stay with the 1.5" front and 1" rear spacer lift given the JLU 4xe is already 1" taller due to the stock springs.

If we wanted additional height to the Mopar lift could we add in some spacers for another inch or two? Or you can't add a spacer lift on top of the Mopar lift?

Yes - it's common practice for some to add a spacer to the front of the Mopar kit just to level it. But you have to consider the new height and what other parts you may need (track bar, adj control arms, etc).

I went with a Teraflex 1 inch front spacer and 1/2 spacer in the rear with 35s. I couldn’t be more happy with the look. I was originally was going to go 1.5 in the front in 1 inch in the back, but the gap was to much.

Was there ever a new part number released?
Any chance anyone knows about this one?

My 37s are taking up too much space in the garage and I need to get a lift on so I can install these suckers :) Want to be sure I don’t end up with an old Mopar lift though.

I do not recall the # your dealer should know it was also my understanding the old part# we all recalled.

I wish I trusted my local dealers enough to know these details 😂 Unfortunately, one thing I’ve learned over the years is that at least around here, the dealers almost never know as much as we do in this forum.

@JeepCares is on the ball and knowledgeable, maybe you can help confirm?

I was told the p/n remains the same at 77072522. That's what I bought & it's on a 3 to 4 week backorder.

I'd encourage you to call Mopar Performance Parts 1-888-528-HEMI to get the definitive answer.
