About this kit
5-Inch Torsion Drop Lift Kit with Vertex 2.5 Shocks, fitment-checked
Vertex 2.5 reservoir shocks are what set 111055 apart in the 5-inch torsion bar drop range: 5-7 In front units and 3.5-7.5 In rears, matched to a laser-cut crossmember and supplied knuckles for 2020–2026 Silverado and Sierra 2500 HD/3500 HD. Rear overload springs are required. Dually, AT4X, and ZR2 trucks do not fit, and neither do factory wheels.
This 5-inch torsion bar drop lift kit for 2020–2026 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD trucks carries Rough Country's Vertex 2.5 reservoir dampers, sized 5-7 In at the front and 3.5-7.5 In at the rear. The front height comes from dropping the torsion bars, so axles hold their factory position and angle and the differential is left alone. Rear overload springs are a hard requirement. Dually, AT4X, and ZR2 models are excluded, factory wheels will not clear, and gas trucks may need exhaust work for driveshaft clearance. A downloadable installation guide is available.
