    I installed rear 4" lift springs from Pro-Comp recently. One of the degree shims is cracked and missing the back half. I'll figure out the actual degree by using trig, but and however comma, I still need to know what the correct angle SHOULD be and if I should move the 1" crossmember spacers back to stock position.???

    Here's the other question: Am I better off using the stock springs and the ORD reverse shackle? If so, what if any degree shim should I use and where should the 1" crossmember spacers go? Now that I own the Pro-Comps, I hear that they are junk springs. I noticed the bottom leaf is no longer lined up with the rest of them on both sides.

    A good degree is 1-3 degrees of angle. You need to match the angles of the u-joints(front and rear) so that they are the same in order to cancel each other out. /forums/images/graemlins/usaflag.gif /forums/images/graemlins/burb.gif
