14-18 GM 1500 2wd 4.5 Cast Steel Arms

This 4.5" lift system from Zone Offroad is designed for 2WD 1/2-ton GM trucks, specifically the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500. It mimics the geometry of FMVSS No.126 compliant 4WD lift systems and includes fully boxed heavy-duty crossmembers and robust ductile iron steering knuckles. The kit corrects suspension geometry, increases ground clearance, and allows for larger wheels and tires. It uses bolt-on strut spacers to retain factory ride quality and includes brake line brackets, sway bar relocation, rear 4" blocks, u-bolts, Fox rear shocks, and all necessary hardware. Important Fitment Note: GM produced several knuckle/control arm configurations in 2014-2017 models. Trucks with Cast Steel control arms require the C35 kit. Trucks with Stamped Steel and Aluminum control arms require the C36 kit. Customers must verify their factory control arm type before ordering.
