50 YEARS OF INNOVATION
In 2024 we mark a half a century of suspension innovation, all with the purpose pushing potential further and giving our athletes and riders the winning edge in racing. A legacy of victories on the world stage, from World Cup Downhill mountain biking to grueling off-road events such as the Baja 1000, is fueled by a mindset that at FOX, Weโre Never Done.

Upper Control Arms (UCA) are considered the first step when building a mid-travel truck, to unlock the vehicle's off-road capability through though 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.
UCAs provide the recipe for an off-road capable vehicle. With FOX, bolt-on a billet arm to maintain wheel alignment and maximize articulation through challenging terrain for more driver confidence.
