3.5-Inch Suspension Lift Kit

The Superlift 3700 suspension lift kit provides a 3.5-inch lift for 2007-2016 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD trucks equipped with the Cast Steel front suspension. This kit features forged aluminum upper control arms with pre-installed ball joints, a front differential drop with skid plate (4x4 specific), and lift blocks with U-Bolts for the rear. The lift is achieved through a top-mount strut spacer that retains the factory front shock and spring assembly, preserving the factory ride while allowing for aftermarket shock use. It offers ZERO cutting or trimming of crossmembers and allows the use of factory wheels without spacers, while retaining OEM caster and camber specifications. It will NOT fit trucks equipped with factory Aluminum or Stamped Steel suspension. Additionally, it is NOT compatible with vehicles equipped with Magnetic Ride Control. The kit provides clearance for up to 33-inch diameter tires without requiring fender trimming. Rear lift is achieved with a block and U-bolt kit, and the kit includes Superlift Shadow series extended length shock absorbers for the rear. Superlift also offers a limited lifetime warranty on fabricated components and a Factory Warranty Assurance Program.
