Upgrade the rear suspension performance of your ReadyLIFT-equipped Chevrolet Silverado 1500 or GMC Sierra 1500 with the ReadyLIFT Falcon 3.3 Fast Adjust Rear Shock Pair.

Designed for compatible ReadyLIFT 6" lift systems, these premium rear shocks provide on-the-fly adjustability for enhanced control, comfort, stability, and damping consistency. Three main compression settings and eight micro-adjustment levels allow the suspension to be precisely tuned for daily driving, towing, trail use, and changing terrain.

The Falcon 3.3 shocks also provide improved heat management and more consistent damping under demanding driving conditions. Their vehicle-specific design delivers bolt-on performance engineered to work with approved ReadyLIFT suspension systems.

This product includes two rear shocks only and is not a complete suspension lift kit.
