11-13 GM HD 5in Sys w/Top Overld - Nitro (C13N)
The heart of the Zone Offroad 5" 2011-18 HD lift kit is a pair of one piece ¼" steel crossmembers combined with the CNC machined steering knuckles to create OE geometry for a quality ride. Also included is a laser cut differential skid plate, differential support brackets, torsion bar brackets, sway bar links, offset rear 3" lift blocks, stainless steel brake lines and custom valved shocks. This system is designed to level the truck and has zero change to the vehicle's track width allowing for clearance of up to 35x12.50 tires. No differential trimming required!
