Reference Information

Shackle Flip Kit, 4.0 in. Lift, Chevy, GMC, Kit

Superlift shackle flip kits can to turn the factory rear tension shackle into a compression shackle for up to 4 in. of lift without using blocks. These shackle flip kits improve pinion angle and reduce or eliminate the need for corrective degree shims. Eliminating or reducing the height of the lift blocks helps to reduce axle wrap and allows for the use of a flatter spring for improved ride quality. The install is easy--just bolt them up to the factory holes with hardware for a stronger-than-stock mounting system.
