2011-2019 Duramax HD 7"-8" Lift Kit w/ SST3000 Shocks (44-3070)

Fits

The ReadyLIFT 7" to 8" Adjustable Lift Kit has been specifically designed to give to a quality lift with rugged off-road strength while maintaining the factory ride on the street. This system features precision-designed laser-cut and CNC-formed sub-frame assemblies that directly bolt in. It also utilizes custom-formed nodular iron knuckles that have been engineered to provide perfect geometry, ride, and handling performance. Also included is an integrated differential drop bracket system to ensure the correct CV axle angles on 4WD applications and maximum performance in 4WD mode.

The front lift is provided by ReadyLIFT Forged Torsion keys which provides an adjustable lift from 7'' to 8'' while maintaining the factory ride. Then in order to lift the rear, this system uses OEM quality cast iron rear blocks that won't sacrifice your ride quality. To top it off, this kit includes tough steel bump stop extensions, skid plate, sway bar end links, and SST3000 shocks for a premium ride!
