Alright ladies. I finally made my roxor drive like a really good daily driver again. The fix? Getting rid of that bullshit 0 degree castor. Mine was actually at -.5 degrees after doing the BMF 5.5 SPOA lift. Brought it to get aligned a few times thinking it was that, it wasn't.
Anyway, I used the following. You only need to do the front 2 but these particular leaf spring bolts came fastest so I got 8. You might find something better for your homes shipping. But you need 2, not 8. You could probably get away with 4 degree shims, but the CJ guys were recommending about 5 degrees positive so this should have me right at about 5.5 right now.
Two notes
Oh also I took out the smallest spring from both sides of the front (I have a 2025 HD) and that helped a lot with bumps!
Guys, when I say it now tracks perfectly, I mean it tracks perfectly. It drives better than at least half the trucks I've owned now. Even on the 38"s.

- If you are spring under axle, the thick end goes to the front. If you are spring over axle (like in the picture), thick end toward the back.
- The centering bolts are MUCH too long. Simply install them and cut the rest off with a cut-off wheel.
- Drill the hole of the shim out a it, its just one or two sizes too small for the leaf spring center bolts.
