Kryptonite’s Boxed Upper Control Arm Kit is one of the most effective upgrades for the front end of your GM HD truck. Whether you’re running stock suspension, a level kit, or most lift kits, these upper control arms deliver improved strength, durability, and ride quality-all while maintaining proper suspension geometry.
