IMHO, I would get it up closer to 6. I’m running 6.4 and 6.5 on mine, no issues. With the 2 pc axle your driveshaft doesn’t spin all the time like it did in the past. If it did you would probably get a slight vibration over 50 mph. Usually you won’t be traveling that fast when your in 4 wd and if you did, it’s a very slight vibration.Had my alignment after 2.5 MC true dual rate installed. Great lift. Tech was very cool and took me under the Jeep on the lift to explain the alignment process.
I see everyone talking about 4-6 degrees caster but he was concerned about the pinion angle.
It does drive nicer after he adjusted the toe. Do I need to adjust the caster more?
There is a little personal preference with caster. Mine is set at 5.8 which is very close to a 0 pinion angle, and I have no problems at all. Just my opinion but 2.8 seems pretty low. At a minimum I would try and get it back in spec around 4.5 degrees. Adjusting your caster will impact your toe and it will need to be checked or set again if you change your caster. On the other hand if it’s driving nice and you like the handling you could leave it alone.Had my alignment after 2.5 MC true dual rate installed. Great lift.

It is driving nice but I have a slight bow in my driver side spring that I hate. It's been there since install. It was recommended that my low caster angle is likely the culprit throwing the perch at an angle.
your adjustable upper control arms should get you whatever you need. To get some caster back you either have to shorten the upper control arms or lengthen the lower control arms. It doesn’t take much of a change to make an impact.
7 degrees seems to be a lot of caster unless your running 40 inch tires. I’m running just under 6 degrees. The only way to properly adjust the caster is by purchasing new lower or upper control arms that are adjustable. I wouldn’t recommend a caster kit for a Jeep. There are lots of options for adjustable lower control arms and they would worth the money. I am surprised the terraflex kit pushed the caster out to 7 degrees, that doesn’t seem right, you might want to give them a call and confirm that is the intended caster.I just had my ‘18 JLUR aligned after installing 2.5” Teraflex ST2 lift. They said that the caster is not adjustable? It’s at 7.1 . I’ve seen others in this thread saying 6.0 is ok? How to adjust if it’s not factory adjustable? Caster kit?
Double check with Teraflex, maybe you got lower control arms for higher lift....I just had my ‘18 JLUR aligned after installing 2.5” Teraflex ST2 lift. They said that the caster is not adjustable?

Man.... it sure looks like you’re on a 3.5” lift, instead of a 2.5”. I’m on 3.5” RK, and you look taller than me, lol.......
That reminded me - I added a Rough Country 3/4” spring spacer based on a recommendation I saw by [Banned Site] saying that the spacers will correct for the weight of the winch (going on tomorrow). I wonder if that is what is throwing off the caster?
I don’t think so, the higher you go, the less caster you have. There was another member on here a while back that had the same thing happen with the same lift, but I never heard what he found out. Maybe they’ll see this and reach out.
True. The thing definitely pulls tho, usually to the right, which I've read is a symptom of high caster. Hopefully I'll hear back from Teraflex tomorrow.
