About this part
Leveling Kit, fitment-checked
The trim list names the off-road heavy duties rather than excluding them (ZR2 on the Silverado 2500 HD, AT4X on the Sierra 2500 HD) alongside the fleet and luxury trims.
Off-road trims on a heavy duty truck usually mean a separate part number, so it is worth noting that this part names them. The Chevrolet Silverado 2500 HD appears in Custom, High Country, LT, LTZ, WT and ZR2, and the 3500 HD in Base, High Country, LT, LTZ and WT. On the GMC side the Sierra 2500 HD runs AT4, AT4X, Base, Denali, Denali Ultimate, Pro, SLE and SLT, with the 3500 HD listed the same minus AT4X. All four run 2020 to 2025 with no drivetrain condition.
