Honestly though, easiest thing you can do for the time being is lower the tire pressure. in 37's, anything over 33 psi is way too high. and 33 psi is being conservative.

Have you tried the chalk test on your tires? I know you said you put the stocks back on, but it seems to be a standard that they are coming over inflated as well.

But again, I bet it is your axle being out of alignment. The dealership may have done an alignment twice, but an actual jeep/offroad shop will put caster, pinion correct as well as center the axle correctly. I have had the same thing done at 3 different dealers with a hard right pull on my first JK until I went to an 4x4 shop. If you dont want to deal with it yourself go to Globex Performance. They are one of the best 4x4 shops in the tri-state area, and are located in Jersey.

Only thing is the Mopar lift doesn't come with adjustable control arms. Toe doesn't get touched during this install either. Kinda weird.

Hmmm, wonder how they address the change in Caster, lower or lift and caster changes, toe should not and unless things have changed camber is set when the build that axle for that vehicle line.

Toe can have a toe out/in on one wheel and not on the other if you adjust the connecting bar from one end only, I have seen that happen. Not sure what the front suspension looks like, but if you have an adjustable connection on both ends of the connecting it would be possible to over/under extend one side, your steering wheel might stay centered, but a pull to the right could occur...

So true, guess they figure not enough change to matter, which is tru for 2".

Toe... is not messed with in a basic lift. So really strange for it to pull in this case

Funny you mention that. Are you familiar with OK 4WD? I had a lifted Sierra Denali that they did, awesome job, great people. Being primarily a jeep shop, the dealer reached out to them to get an opinion. We decided to go with an adjustable rear track bar under the assumption that the axles off. It should be here early next week...

Some good stuff below. Remember to be sure the angles remain the same between the trackbar and drag link afterward to avoid bumpsteer issues, and be sure they use extra thick bolts to avoid play in the mounts down the road (wobble issue). Little more work going with the lift but should be awesome once it's dialed in.

Yes maybe a tad, but for all the lifts that have been installed why has that not been an issue so far?

I'm with ya on that. Who knows. There have been quite a few people with the Mopar lift and 37's and no problems. Again, not really sure what the issue is. Hopefully the track bar solves it.
I did take off the Fox steering stabilizer and replaced it with the stock one. I noticed a difference, but it wasn't a total fix.
For now, I'm leaving the Fox SS on and we'll get that rear track bar on next week and see what happens.
If it's not fixed, I'll try swapping the SS to see if it makes a difference.
One step at a time!

Which Fox do you have....the 2.0 with adjustable bypass?

But have you checked it? Pulling to the right means they didn't do it right.
sounds like the did it "to the right", not right, correct?, lol

What Mark Doiron said can't be stressed enough. Also, put the stock steering stabilizer back on and leave it on. Aftermarket ones are notorious for causing slight pulling issues.

Very true/

looks like Fox Racing Shox 985-24-173 2.0 Performance series is not adjustable. So could be pushing you right. I have the
Fox® Racing Shox 2.0 Performance Series ATS Steering Stabilizer and it gave me problems until I backed the valve off to setting 7 (of 24)
