About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
A 6-inch lift kit for the 2025–2026 GMC Sierra 1500 in Elevation, Pro, SLE, and SLT trim, 4WD or RWD, with an N3 shock pair, a full front skid plate, a high-clearance crossmember, and cast knuckles. It does not fit Denali or Denali Ultimate trucks, AT4, or AT4X. Cutting and drilling are part of the install.
Sierra 1500 owners in Elevation, Pro, SLE, or SLT trim are the audience here; Denali, Denali Ultimate, AT4, and AT4X trucks are not covered. Damping comes from an N3 shock pair, and the 6 inches of height are carried by a high-clearance crossmember, cast driver and passenger knuckles, and fabricated rear blocks, with a full front skid plate covering the underside. Both 4WD and RWD configurations from 2025–2026 are listed. Cutting and drilling are required, and factory wheels have to be replaced with 20-inch or larger wheels running 4.5 in backspacing.
