ReadyLift, the company that started a revolution in truck & SUV Leveling now puts you in control of your ride with ReadyLift SST Shocks! Featuring the highest quality nitrogen charged, internal reservoir design and construction, every ReadyLift SST9000 Shock is precision tuned and pair matched to provide the control you need when adding larger tires and wheels to your Jeep, Truck or SUV. ReadyLift SST9000 Shocks are available for most popular makes and models of trucks and SUVs. Each vehicle application has been rigorously tested to develop a unique valving system specific to that vehicle, particularly those vehicles which have a ReadyLift leveling or SST Lift Kit installed. ReadyLift offers a Limited Lifetime Warranty on all of its products.

ReadyLift SST9000 Shocks are not designed for universal one size fits all use. Every SST9000 Shock and valving is specifically engineered, tested and produced for the intended vehicle make and model application. Years of research and development have led to vehicle specific valving that is optimally tuned for use on lifted or leveled trucks using larger, heavier wheels and tires. SST9000 Shocks will also work on some factory height vehicles.

99-3411R rear shocks for the 2011-2012 Chevy Silverado 2500HD/3500HD 2wd/4wd trucks are designed to be used on trucks with 0-2'' of Rear Lift. This is the ideal shock for trucks with stock rear heights or those using either a 1-2'' rear lift block.

Low cost over the counter replacement shocks use factory level shock valving which is exactly why factory shocks can wear out much faster once a larger, heavier wheel and tire combination is installed. That is exactly why the ReadyLift shock technicians worked tirelessly to engineer specific valving that accommodates the increased shock cycling dynamics of a vehicle with aftermarket wheels and tires.

Even better news is that the ReadyLift SST9000 shocks will enhance your ride! In every application the specific shock valving performance far exceeds that of the factory shock which means your truck will ride, handle and perform better!

Peace of mind guarantee, Just like with performance racing shocks, every SST9000 Shock is completely rebuildable and revalvable!

Every SST9000 Shock is completely manufactured right here in the United States of America!
