2011-2019 GM HD Rear SST3000 Shock 7.0-8.0 Lift (93-3156R)

The ReadyLIFT SST3000 Performance Tuned Rear Shocks for the 2011-2019 GMC/Chevy 2500/3500 HD are precision-engineered dampers specifically designed for heavy-duty trucks with 4 to 5 inches of rear lift. These shocks offer an affordable way to gain the performance characteristics of high-end suspension systems, featuring application-specific custom valving that ensures a comfortable ride both on-road and off-road. Engineered to control the heavy forces of larger diameter wheels and tires, the SST3000 series provides the stability and damping required for lifted heavy-duty applications.
