ReadyLift 44-39605 6" Big Lift Kit With Falcon 1.1 Monotube Shocks

The ReadyLift 44-39605 6" Big Lift Kit With Falcon 1.1 Monotube Shocks is designed for superior handling performance in your GM Silverado/Sierra 1500 2WD/4WD.

New 5" fabricated steel rear blocks with built-in bump stop landings and new Bilstein 5100 series rear shocks have been fitted to raise the rear.
