I put a new lift kit on my 72 blazer used the poly bushing that came with the kit. Drove like a dog. Finally figured out the poly bushing in the the shackle are not biting into the shackle like the oem ones do. if you stand on the rear bumper and jump up and you can see the shackle move. This is allowing the rear end and spring to move when I apply the brakes or turn. Have an old oem set that I will switch back to
