Fox Racing Fox Control Arm Kit - Black (2019-2025 Sierra 1500, Silverado 1500, Silverado 1500 LTD, Sierra 1500 Limited) - 803-35-008
The Upper Control Arms (UCA) are consider the first step when building a mid-travel truck to unlock the vehicles off-road capability through tough terrain.
Our engineers spent time evaluating suspension geometry and optimized the UCAs specifically for the intended vehicle. Lifting a vehicle compromises the OEM alignment specification by introducing too much caster FOX UCAs provide the necessary correction to maintain the vehicle's alignment while maximizing droop travel for more articulation off-road. Additional caster helps reduce wander at high-speed for more confidence behind the wheel. You'll notice a precise comfortable ride on rougher roads and trails.
FOX upper control arms are CNC machined in the USA from T6061 billet aluminum. Type II anodization offers superior corrosion resistance and feature a laser etched FOX logo
1.25" uniballs are comprised of a hard chrome plated ball and low carbon steel race to increase service life. A PTFE liner mitigates noise to keep the ride comfortable
The 3/4" chromoly heim joints are fully adjustable allowing for fine tuning of caster and camber. The Kevlar fiber reinforced PTFE liner to prevent binding and long-lasting precision
Stainless-steel taper misalignment spacers and 12-point bolts at the steering knuckle ensure a reliable and precise fit. Bolt-on the UCAs without any modification to the vehicle chassis
