Adjusting rear after spring relocation?

[Coyote Jack]

I am about to relocate my springs into the frame. I am using a kit from RMS. I understand how to install the kit but I do have 1 question. After installation which I am going to get as square as possible which is never perfect. How do you adjust the rear to get it perfect? With the stock mounts you could loosen one side off and add shims until you got the rear square. What do you do with it after the spring relocation? I run an 8 3/4 with SS springs if that makes any difference.

You could relocate the hole in the spring perch. The ultimate way is to have it on an alignment machine that measures a live thrust angle.

True, but I don't want to turn my frame box into Swiss cheese.

Spring Perch.

Slot it forward

Mine came out 3/16 off. Not too bad if you ask me. If I wanted it closer I would drill the perch out larger and machine an offset bushing.

Thanks. That sounds like a good way to adjust. Make different size bushings to tune it right in.
