Superlift 2014+ Silverado & Sierra 1500 4WD 3.5" Lift - Cast Steel Suspension # 3700

Superlift has introduced a new series of lift kits to their product line. The unique Superlift Leveling Kit design adds strength and durability that other manufacturers simply do not offer. The Superlift Upper Control Arm (UCA) has a modern, fitted steel structure that gets its strength from the classic ‘I’ beam architecture. The distinctive design uses high quality components and features ZERO cutting or trimming of the crossmembers. You can run factory wheels without wheel spacers and even retain the OEM caster and camber specifications. This Superlift 3700 kit fits the 2007-2016 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the Cast Steel front suspension. The 3.5” Lift height provides a level stance and clearance for up to 33” diameter tires.

This Superlift 3.5" Lift / Leveling Kit # 3700 is designed for use on the previous generation 2007-2013 and current 2014-2016 Silverado 1500 4x4 and Sierra 1500 4x4 trucks equipped with the Cast Steel front suspension. This item will NOT fit Aluminum or Stamped Steel suspension equipped trucks! This kit comes complete with new upper control arms that include pre-installed Moog ball joints. A front differential drop and front diff skid plate are also included and are 4x4 specific components. The lift is provided by the top mount strut spacer that is designed to allow you to retain your factory front shock and spring assembly. This cuts down on cost, retains the factory ride, makes installation much easier and still allows the use of aftermarket shocks if you so desire. The rear lift is provided via a set of lift blocks and longer U-Bolts. To complete the rear suspension Superlift includes a pair of their Superide extended length shock absorbers.
