Of course it will, they lifted it and, just lifted it.
Out of curiosity, I compared the took off lower control arm from my 18 JLUR, they are the same.
So for the people don't know, your caster angle decrease as the vehicle lifts, so people put longer/adjustable lower (at least) control arms to get proper caster angle. Think of wobbling shopping card wheel, that has 0 caster. More caster will help it track straight.....think bicycle/motorcycle..

Still love it 200%.....

Mines pretty good maybe a little movement at 70 mph and some cross wind it will move around some. I had planed to swap lower control arms just have not ordered them yet. Probably just do the Mopar lowers off the 2" lift for now and see if there is a improvement.

I am really surprised they haven't dialed more caster into these from the factory by now. It is well known that the Mopar Lift LCAs help in almost every instance. That and the Yeti track bar improved my steering SIGNIFICANTLY

If the collective assertion is true that higher part numbers were taller springs in Rubicon’s, it seems lately that the ‘21 Rubicon owners are only showing numbers ending toward or at the 58/59 end of the spectrum rather than 61/62 (gasoline springs) anymore. My point being, maybe that is their interim way of getting more caster and less complaints for now. My ‘21 Rubicon rides better with the lower numbers (58/59 & 88/89)than my Sahara with the Rubicon suspension with 61/62 up front and when it had 90/91 out back.

Anyone with a ‘21 2.0 or 3.6 Rubicon have higher numbers?

Do you happen to know the part number for those lowers? I was thinking of doing the same thing.

May be the worker didn’t pick the “right” control arms. Some 392 owners says their tailgate plate is not the special golden 392 one….

What is this golden plate you speak of? I don't have it either!
On the Tailgate there is a plate showing jeep info, The 392 should have a golden colored model specific plate. Mine and apparently several others do not. Mine is just standard silver JL and has the wrong info on it.

Interesting. Maybe using higher springs on xtreme recon for differentiation from standard rubicon. So did they effectively “lower” the std ‘21 Rubicon ride height? Hmmmmm.......

easy to play with existing parts for them
