About this kit
6-Inch Diesel Lift Kit, fitment-checked
The diesel version of Rough Country's Adaptive Ride Control 6-inch lift kit, 110100D. It fits 2025 Silverado 1500 High Country with Adaptive Ride Control and Sierra 1500 Denali and Denali Ultimate, in 4WD or RWD, and swaps in a diesel-specific front kit alongside the high-clearance crossmember and cast knuckles. Cutting and drilling are required.
Two things narrow this kit down, and both matter before you order: the front hardware is the diesel-specific version, and the truck has to have Adaptive Ride Control. That means Sierra 1500 Denali and Denali Ultimate, where the system is standard, and Silverado 1500 High Country trucks ordered with it, in 4WD or RWD across 2025. The rest of the 6-inch package is the high-clearance crossmember, cast driver and passenger knuckles, and fabricated rear blocks. Cutting and drilling are required. Factory wheels will not clear; 20-inch or larger with 4.5 in backspacing is the requirement.
