Had a BAD rear driveline vibration in my K5 when I first got it... I mean BAD... 4" rear springs only. Got a shim from the 4x4 shop(can't remember the angle), but it fixed it right up.

If you are willing to wait, I am pulling the shims soon and adding angled 2" blocks, and you are more then welcome to them for shipping costs only.

Only thing is, less of the center pin contacts the spring perch, and it looks like I have sheared a center pin in back (based on axle location). If I used a new center pin when I installed the shims, it probably would have been fine. These shims go between the spring pack and perch... they don't bolt to the pack like Superlift or others would.

Food for thought. Let me know.
