This Zone C27N lift kit for the Chevy Silverado 1500 includes a pair of fully boxed heavy duty crossmembers and robust ductile iron steering knuckles engineered to work with the redesigned steering. A 3-piece differential relocation system is utilized to correct front pinion angle with the center differential brace tying front and rear crossmembers together for a sturdy differential mount. This coupled with the differential skid plate and crossmember brace create an incredibly strong front subframe designed to correct suspension geometry while increasing ground clearance.

To retain factory ride quality a pair of bolt-on 4.5 inch strut spacers are used to provide lift. These install easily without the need to disassemble the factory strut. Also included in the kit are a pair of CV spacers, brake line brackets, sway bar relocation, and all the necessary hardware to complete the install.

To lift the rear and level the stance a 4 inch tapered block is utilized along with longer u-bolts, brake line bracket and your choice of shocks.

New for GM 1/2 Ton's is the availability of both forged steel and forged aluminum control arms from the factory. Zone Offroad Products offers kits to fit both steel and aluminum arm equipped trucks. Check your vehicle before ordering to ensure the correct kit is shipped. Accessories for this lift kit include Zone front skid plate available separately.

As with all Zone Offroad Products, this 4.5 inch lift kit is backed by a limited lifetime warranty.
