ReadyLift now offers specially designed Rear Shock Extensions for 1999-2015 Chevy Silverado and GMC Sierra 1500 2WD and 4WD trucks. These tough powdercoated steel shock extensions install in the factory upper rear shock mount to greatly decrease the chance of over-extending the factory shocks. These new shock extensions are designed to be use with factory shocks on '99-10 GM 1500 trucks with 3" rear lift blocks. Rear shock extensions are not required for every application using a rear lift block and factory shocks. However, if the vehicle owner uses the truck in any off road environment which results in excessive rear suspension cycling, the stock rear shock may not be long enough and "top-out". Rather than purchase costly new rear shocks the solution is to install a set of ReadyLift rear shock extensions for a fraction of the price of new aftermarket shocks. Recommended for use with ReadyLift 66-3003 3" Rear Block Kit on trucks that will see off road use. Can also be used with ReadyLift 66-3002 2" Rear Block Kit on trucks that will see off road use. Not designed for use with GM SUVs.
