Bumpsteer, Caster, and Geometry Brackets

[Kum4224]

After running a mopar lift with stock steering components on my JLU Sport for 4 years, I finally got around to getting some adjustable front and rear trackbars by Synergy and some rancho geometry correction brackets to improve wander. I got the brackets installed on the top most hole (the lowest setting) and utilized my Mopar extended LCAs with it since I don't have the factory ones with me. The Mopar ones are only about 1/8" longer eye to eye than factory.

Just got it back from the shop and my alignment shows castor at 7 & 6.8 degrees. Steering does feel pretty heavy but not crazy heavy. And on speedbumps or driving through intersections that have a bump, I do see some bumpsteer. Prior to brackets, my castor was at 5.5 & 5.4 with the extended arms.

Is my castor too high? Should I be trying to find factory arms to help bring it down a bit? Jeep drives really steady, just sometimes I feel the heaviness is on the higher side. And im wondering if the bumpsteer is happening from too much caster or something wrong in the trackbar install.

If I remember correctly, castor angle seemed to have a sweet spot around 6 - 6.5 degrees. This may vary depending on how much lift. I don't know if that's causing your occasional bumpsteer. I personally would prefer a quality set of adjustable LCA's vs geometry brackets & fixed LCA's. Especially if its needed to go back and re-adjust the castor angle.
