Front axle shims

[PHC CK5]

I have a Dana 60 front, did the b-52 upgrade with 52" springs. Took out overload spring and is left with 4 leaves. What degree shims should I get? Was also thinking about switching to the DIY4X spring plates and doing the front rear shackle eyes to the bigger ones. Thanks in advance.

There are literally so many variables that we cant tell you "for sure." Have to assemble everything (full weight of vehicle on the suspension) then measure the driveshaft angles and order the correct shim. If the springs are brand new there is also a break in that will occur, so the ride height will drop a little (usually 1/2" or so) over the first month or two of use.

The rear shackle upgrade is extremely common. Known weak point in that little 7/16" bolt. Also its a known wear point, the bushings just get old and oval shaped.

Likely 6-8 degrees. Too many unknowns to tell you.

The front springs came from another blazer from the rear.
