FOX 803-35-009 Billet Aluminum Upper Control Arms for 2019-2024 Chevy Silverado and GMC Sierra 1500

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 | (2019-2024) 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.
