Zone Offroad Heavy-Duty Upper Control Arm Kits. The new upper control arms provided in these kits are direct replacements for the factory arms. Made from fully weld 1/8" steel plate construction as well as CNC machined ball joint and bushing mounts, these arms dwarf the factory components.

In addition to overall strength of construction, these new arms trump the factory components by providing more range of motion. This feature benefits multiple suspension setups from simple leveling kits to full replacement steering knuckle-style suspension systems. The arms utilize high quality Raybestos brand ball joints that can handle heavy duty use and work in conjunction with OE-style rubber mount bushings to provide a quiet ride. The ball joints are greaseable and easily replaced with readily available parts at the end of their service lift. Proper brake line attachment points are included on the arms where needed for a factory-like fit.

Important Notes!
For leveling kit installations, the new arms should only be paired with the replacement Zone front shock #s 4615 or 7615.
C5201 shock relocation brackets should not be used.
Not designed to be used with Zone's 6" kit
Not designed to be used on a stock height vehicle
Includes a pair (2) of upper control arms
