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. GMC SIERRA & CHEVY SILVERADO | UPPER CONTROL ARM | (2019-2025) FOX Upper Control Arms feature a lifetime warranty on the aluminum arm. This is backed by a 12 month warranty on all serviceable components and finishes.

• 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
• 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
• 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
