Part #: ZON C43F
Manufacturer: Zone Off Road
Front:At the heart of these new 5" lift kits Zone Offroad utilizes a pair of 1/4" thick, American steel fabricated drop crossmembers to reposition the OE lower control arms. These crossmembers offer additional ground clearance and are paired with full width Zone Offroad branded skid plate to create a strong subframe with added protection for critical steering and driveline components. In place of the factory steering knuckles a pair of specially designed CNC machined ductile iron steering knuckles are used to maintain proper steering geometry for ESC system compatibility at the taller ride height. The front differential is secured in its new location using a multipoint differential relocation brackets that key off the factory mounting locations as well as the top crossmembers to extra rigidity and keep CV axle operating angles similar to stock. These systems retain the factory torsion bars to maintain ride quality and spring rate. To compensate for the lift a pair of Zone branded torsion bar crossmember drop brackets to position them correctly. A set of specially tuned FOX 2.0 Adventure Series IFP shocks are supplied to further enhance ride quality and offer improved offroad damper performance. Rounding out the front of this new 5" lift kit are longer sway bar links to correct sway bar operating angle, bump stop extensions to properly limit up travel, and extended length stainless steel brake lines.
Rear: In the rear of this 5" lift kits, a pair of tapered rear 4.5" lift block and longer black e-coated u-bolts to lift and level the stance. These blocks use an offset in location to center the rear axle in the wheel well. Rear brake line brackets are supplied to allow you to retain your factory rear brake lines.
