Went into the driveline place this morning and found out my 2/4 drop has screwed up my pinion angle, which is causing my vibration. Because I have coils in the back, I can't shim the rear like you could easily do with a leaf spring rear. Instead, my only recourse is to either lengthen the lower control arms (trailing arms) or shorten the upper control arms.

Since I have the Hotchkis heavy-duty lower arms, I'd like to keep them and find some uppers that are either shorter, or adjustable. Does anyone know of a place who makes these, has these, or could help with this issue?

 

typically, if unavailable, you can make them by using threaded heim joints and a pc of steel with threaded inserts welded in.

 

"Trailing arm brackets are also used to allow the axle to move up with the new coil springs. This bracket keeps the trailing arm at the correct angle"

One more, this looks like a good read:

Looks good, I will try and get this bracket - thanks.
