1.5" upper-strut-spacer front leveling kit for the new-body GM 1500 without Adaptive Ride Control.
A redesigned leveling solution for the new-body GM 1500 that uses an all-new upper strut spacer instead of the horseshoe bottom-strut design, reducing the risk of contacting the CV boots during installation. Machined from CNC 6061-T6 aircraft-grade billet aluminum with a design specific to the 2019-2025 GM 1500 struts.
