ReadyLift - 2"F/1"R SST Lift Kit - 2019-2023 GM 1500 (Trail Boss/AT4) - 69-3920

2"F / 1"R SST lift kit for factory-lifted 2019-2023 GM 1500 Trail Boss / AT4.

The ReadyLIFT 69-3920 SST Lift Kit works with the factory 2" front lift on GMC AT4 and Chevrolet Silverado Trail Boss 1500 trucks, adding 2" of front lift and 1" of rear lift. It uses a top-mount strut spacer, pre-load spacer, and premium upper control arms, avoiding the binding and clearance issues of a traditional leveling kit on these factory-lifted trucks.

Fits: 2019-2023 GMC Sierra 1500 AT4 and Chevrolet Silverado 1500 Trail Boss (4WD, factory-lifted).
