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!
