Quick Overview

The ReadyLift 2.25" lift kit for the Chevy Silverado and GMC Sierra Z71 is guaranteed to keep your factory ride. This 100% bolt-on suspension lift kit includes front SST 4.0" strut extensions, CNC machined differential drop spacers, DOM tubular control arms with new evolution, heavy duty pre-pressed ball joints, polyurethane greasable bushings with backing spacers for extended life. The rear is lifted with a replacement 3" block kit. Rear shock extension brackets are included so there is no need to replace your rear shocks.

The differential drop mounting system utilizes machined billet circular spacers which allows for just the right amount of differential drop without interfering with the new rear mounted electric steering rack. Additionally, a newly designed skid plate accompanies the differential drop system.

The heavy duty ball joints included in this lift kit are vastly superior to factory and come installed into the upper control arms. Also included are The ReadyLift newly designed UCA inner bushings and new washer backing spacer sleeves which greatly prolong the life of the bushings.
