2001-2010 GM HD Boxed Upper Control Arm Kit (KRUCA10)

Description

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.

Built from precision laser-cut steel and TIG-welded into a rigid boxed design, these arms are engineered for performance and longevity. Included bolt-on ball joints and hardware make installation straightforward, and the arms are fully serviceable.

For added alignment control and long-term durability, Kryptonite recommends upgrading with the optional Cam Bolt Kit #KR0026, especially if your truck sees off-road use, harsh winters, or has high mileage.
