Designed for the Rough Stuff. Your 2500 was redesigned by GM in a big way - there’s no better way to complement the aggressive styling than with a significant height increase. This SuperLift 6-Inch Knuckle Suspension Lift Kit with Bilstein Shocks uses a “No Drop” torsion bar relocation bracket that keeps the torsion bar assembly safe for off-roading while maximizing frame ground clearance. This Superlift Kit can expand your tire choices up to 37-inches while keeping perfect alignment specifications with CNC machined steering knuckles and heavy-duty lower control arm crossmembers. This kit includes steering knuckles, crossmembers, torsion bar brackets, front sway bar links, belly pan, brake line brackets, bump stops, rear block kit, and shocks; all required parts to make sure your Sierra handles and performs like a stock truck.
Bilstein Shocks. Bilstein 5100 Series shock absorbers are a direct fit for your lifted GM 2500. These shock absorbers feature a monotube design that provides consistent fade-free performance. In addition, 5100 Series shock absorbers utilize a unique, velocity-sensitive, digressive piston that reacts to changing road conditions - more firm at low speeds while remaining comfortable on the highway. Bilstein 5100 Series shock absorbers significantly improve ride quality, handling, and comfort.
Rear Lift. A fabricated rear block provides the rear lift, while the primary axle U-bolts are found in the upper and lower plates, with the secondary U-bolts attached to the OE leaf spring to reduce pinion wrap. An axle-mounted, compression stop system prevents over-compression.
Installation. Installation time is estimated at 9 hours with mechanical expertise or a professional installation. No welding is required. This kit is compatible with factory Stabilitrac® and anti-skid control features to prevent irritating dash lights.
Limited Lifetime Warranty. Superlift, LLC, is so confident in its suspension products that they carry a limited lifetime warranty on fabricated items and a 1-year warranty on all wearable items such as bushings, stabilizers, and shocks. Subject to the terms and conditions, please contact the manufacturer for full warranty details.
