ReadyLIFT Suspension Inc. is excited to offer the popular 3.5"F/1"R SST Lift Kit for Chevrolet and GMC 2500HD and 3500HD trucks. This is a true bolt-on lift kit that provides a premium lift solution without permanently modifying your truck or breaking the bank. The kit lifts the front a maximum of 3.5 inches and the rear 1 inch. This awesome SST Lift Kit includes a pair of tough, heavy-duty tubular steel Upper Control Arms engineered to match the strength of your truck, along with HD-specific lift-oriented ReadyLIFT forged torsion keys that provide an adjustable lift while maintaining the factory ride. The kit also includes CNC-machined differential drop spacers which lower the differential and put the front CV axles into a safe factory angle on 4WD trucks (2WD trucks will not use the diff spacers). To lift the rear, the kit includes original equipment manufacturer (OEM) style 1.0 inch cast iron rear lift blocks complete with new U-bolts and hardware. Additionally, new super strong tie-rod end assemblies are included to replace the weak factory versions. This great combination gives the trucks a great raised stance using super strong components and allows for up to a 34 inch tall tire.
