The Upper Control Arms (UCA) are considered 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. FOX UCAs provide the necessary correction when lifting a vehicle to maintain the 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.
