ReadyLIFT is excited to offer a newly redesigned leveling kit for the GM 1500 series 2WD & 4WD trucks.  The new design provides a leveling solution via an all-new upper strut spacer instead of the horseshoe bottom strut design.  This new design helps with the installation process with less risk of contacting the CV boots when not installed properly.  These new kits offer a 1.5" leveling solution for the new body 2019-2022 Chevy Silverado and GMC Sierra 1500 trucks. The leveling kit spacers are manufactured from CNC-machined 6061-T6 aircraft-grade Aluminum with a unique design to work with exclusively the 2019-2022 GM 1500 struts.

The 66-39150 leveling kit is specifically designed for the GM 1500 trucks without Adaptive Ride Control whereas the 66-39151 provides two extra brackets to work on GMC Denali and Chevy High Country 1500’s equipped with ARC.

This all-new leveling kit will allow for up to a 33x11.50-20 tire on a 20x9 0 offset wheel (same wheel/tire specifications as the 66-3920 & 66-3922)
