Update:
Caster is 3.1 on right, 3.9 on left with Mopar lower control arms. Synergy adjustable lower control arms ordered and will be installed next week to correct.
That is quite the difference ..huh. defective arms ?

That's waaay low for sure, however........

You can't change caster split on a solid axle vehicle with control arms. It's not possible to twist one end to change caster and not also twist the other end of the SOLID TUBE.

Take any long thing like a cardboard tube from the center of a roll of paper towels. Now, try to move the bottom of ONE end forward while keeping the other end from rotating.
You can't.
If the caster SPLIT was 0.8 it was always that way, even before the lift.

I would suppose so. I will see how it goes with the new adjustable control arms.

That caster is WAY too low, clear out of specs, but don't expect the split to change. Even the low factory number is something like the mid 4s for the lowest part of the range.

He can get it up where it belongs - closer to 5+ at least, but he can't correct the difference.
Getting caster up higher may resolve it by itself. That low is into "wander" territory.

Yes agree totally mine was 4.5 before I changed arms ,after we set it at 5.4 seems to have been a sweet spot for mine , think 🤔 @WILDHOBO said 5.5-6.0 is common setting for lift .. I tried to turn one more time on my arms and it jumped to 6.4 so we went back one revolution and stuck with 5.4 and it worked.

Synergy LCAs installed last Monday. Took a weekend trip to north GA this weekend. Tracked and drove great.
