Sierra 1500 2014-2018 GMC (w/aluminum or stamped steel factory arms) Upper Control Arms by Zone

These Zone Offroad C2313 Heavy-Duty Upper Control Arm Kits for the GMC Sierra 1500 are great replacements for factory arms when paired with leveling kits and larger lift kits. Improves suspension articulation, travel and restores proper suspension geometry. 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. 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.
