The 4.5'' system for the 2WD 1/2-ton GM trucks mimics the geometry of the tried and true, FMVSS No.126 compliant 4WD lift systems. The kits include a pair of fully boxed heavy duty crossmembers and robust ductile iron steering knuckles engineered to work with the redesigned steering rack. This coupled with the crossmember braces creates an incredibly strong front subframe designed to correct suspension geometry while increasing ground clearance. To retain factory ride quality a pair of bolt-on strut spacers are used to provide lift. These install easily without the need to disassemble the factory strut. Also included in the kit are brake line brackets, sway bar relocation, rear 4' blocks, u-bolts, your choice of hydro or nitro rear shocks and all the necessary hardware to complete the install. Optional accessories for this lift kit include Zone front skid plate available separately. As with all Zone kits, this 4.5'' system is backed by Zone's limited lifetime warranty, FMVSS No.126 ESC system compliance, and 5-year 60,000-mile drivetrain protection through
