Rear Axle Degree Shims
I'll throw this question out there. How do I determine the amount of degrees for rear axle shims? I installed Old Man Emu leafs and JKS 1 inch shackles. Any suggestions on the shims, 2, 4, 6 degrees? Thanks.

You measure the TC Output angle and the pinion input angle. If you have a TC Drop or no drop the angles should be with 1-3 degrees of each other, almost paralel. If you have a SYE the rear pinion should point AT or 1-2degrees below the TC output. You use the amount of shim to achieve those targets.
