Looks good. Someone just told me that the longer LCAs aren’t necessary and pull it outta spec for caster. I’m so confused.
You and me both
All that jives. At 1.5" you shouldn't need longer lower arms. If it drives fine and feels good that's all that really matters. If it feels like it wanders a bit too much or you get a bit of wheel wobble when hitting bumps it might be worth trying the lower arms.I’m certainly no wrench turner, however when I researched this issue, it seemed that for a 1.5” lift the lower control arms are not necessary. I also found that many experienced suspension people say the JTRs have limited caster from the factory and the MOPAR Performance lower control arms add some caster as the vehicle is minimally raised. Like I said, I’m pleased with the end result. I wish I was still physically able to do the installation myself.
Jeeps vary a lot from the factory in terms of caster angle, and even caster differences from left to right knuckle. Given it's a CV style front driveshaft, and if you have the part time case the front driveshaft isn't spinning in 2wd thanks to the CAD, it's much less important to find a good tradeoff between caster and pinion angle in the front than it used to be on Jeeps with shorter arms with u-joints on both ends and an always spinning shaft. It usually doesn't hurt to go a bit heavy on caster at lower lift heights if you so chose.
