2011-19 Silverado, Sierra 2500HD, 3500HD Adventure Series Upper Control Arms, 2"-5" of lift

For significant suspension travel and ride quality improvement for your Silverado or Sierra, replace your stock upper control arms with the Zone upper control arms. These replacement boxed heavy duty control arms will dwarf the strength of the factory arms. Fully welded 1/8" steel plate is used in the Chevy Silverado and GMC Sierra control arms construction. More droop travel is allowed by repositioning the relationship between the arm and the factory droop limiter at the frame. This also results in a more neutral upper ball joint operating angle for trucks with either leveling or lift kits. High quality Raybestos brand ball joints are used to handle heavy duty usage and provide a quiet ride by working in conjunction with OE style rubber mount bushings. These ball joints are greasable and can be easily replaced at the end of their service life. Replacement UCA Ball Joint #: 500-1104B (Raybestos) are available at most local auto parts stores.
