About this kit
6-Inch Lift Kit, fitment-checked
Rough Country 110030 is a 6 inch lift kit for the 2025-2026 Chevrolet Silverado 1500 4WD in High Country, LT, LTZ, PPV, RST, and WT trim. Installation requires cutting and drilling. Factory wheels will not fit — plan on 20-inch or larger aftermarket wheels with 4.5in backspacing, and test fit before installing. Trail Boss and ZR2 trucks are excluded.
A high-clearance crossmember does the work up front, paired with heavy-duty cast knuckles and fabricated rear blocks, all laser-cut for a factory-style fit. Stock track width is retained. Two exclusions matter most: LT Trail Boss and Custom Trail Boss trucks already carry a 2-inch factory lift, and ZR2 trucks add DSSV dampers to that lift, so neither is covered. Wheels are the other decision — factory wheels will not fit, aftermarket wheels must be 20-inch or larger with 4.5in backspacing, and some may need the 0.25 inch spacer, part 1065. Shipping weight: 235.0 lb.
