2020-21 Chevy Silverado, GMC Sierra 2500HD, 3500HD Adventure Series Upper Control Arms, 2"-6" of lift
Important Notes
These control arms are approved to fit 2" up to 5" of suspension lift made by Zone Offroad. Before installing on a different manufacturer's lift, a fitment check with the suspension at full droop is highly recommended to make sure the suspension travel is properly limited with the use of these arms.
Quick Overview
For significant suspension travel and ride quality improvement for your Chevy Silverado or GMC 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.
- Improved strength with fully welded plate steel construction
- CNC machined ball joint cup with improved positioning ideal for use with leveling/lift kits
