About this part
Leveling Kit, fitment-checked
Two trims and nothing else: LT Trail Boss on the Chevrolet side, AT4 on the GMC side, 2019 through 2025. No drivetrain condition is attached.
Trucks that left the factory with an off-road package sit differently from the start, which is why ReadyLift gives them their own part numbers rather than one kit for the range. this part covers the Chevrolet Silverado 1500 in LT Trail Boss and the GMC Sierra 1500 in AT4, 2019 to 2025. Unlike some of the off-road-trim kits in this range it carries no four-wheel-drive restriction. The data does not record a lift figure, a tire ceiling or what the kit contains.
