    I got the angles my rear driveline is at:

    78* at the diff and 85* at the t-case.

    The specs:
    6" lift
    36" tires
    front springs, shackle flip rear and ORD add-a-leaf

    Would I be able to get away with shimming the rear axle? If so, how much, 4-6*? Also, the front shaft is really at a severe angle. Can you shim the front also, or...?

    I figured I would have to get my rear shaft lenghtened but it appears that I will not have to. It actually slides into the t-case farther than when it was stock.

    Thanks
    Ross

    You want the degrees within 2 to 4 of each other so either the 4* or 6* shims would work with 6* being the one that will make the u joint most happy. the front shoudl have a cv style shaft and on that you want to point the pinion at the t case output. (most lifts call for a 3 or 4 degree in the front) My trailmaster kti came with a 2.5* shim and my buddies 6" came with the angle already in the pack.
