Product Overview
More Information

These Zone C2312 upper control arms for the GMC Sierra 2500HD / 3500HD pickup are ideal for vehicles that have lifted 2 to 3 inches with either a leveling kit or lift kit, offering improved suspension travel and ride quality over the factory control arm design.

These heavy duty, boxed steel upper control arms are made from fully welded 1/8" steel plate construction as well as CNC machined ball joint and bushing mounts. Built much stronger than the factory arms while improving the performance and appearance of your HD's suspension. High quality Raybestos brand ball joints will 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 life. 

These UCAs were designed for 2-3" leveling / lift kits and have been approved for fitment on Zone Offroad's 5" Suspension System. They may work with other suspension setups but a fitment check with the suspension at full droop is highly recommended to ensure the suspension travel is properly limited with the use these arms.
