The ReadyLift goal is to provide a true 4" lift kit for the Chevy Silverado and GMC Sierra 1500 that is completely bolt-on; no drilling, cutting or welding required. This lift kit features powder coated steel strut extensions that bolt directly to the top of the factory strut with no modifications to the factory strut required. Included are 100% DOM tubular heavy duty upper control arms. These arms feature OEM-style ball joints pre-pressed into a strong crown that retains the OEM geometry. The new control arms also include ultra strong TCT free floating pivot bushings that are self lubricating and eliminates friction. The CNC machined 6061-T6 billet aluminum drop brackets can never bend, break or cause any driveline problems when using 4WD. This is guaranteed!

A thick powder coated plate steel skid plate uses the factory attachment locations. 3" OEM-style rear cast iron blocks and u-bolts include the correct pinion angle correction and will replace the factory blocks. This results in about 1/2" of rear to front rake that is helpful for towing or hauling. Completing the package is a set of steel rear shock extensions eliminating the need to purchase aftermarket shocks.
