FOX 803-35-007 Billet Upper Control Arms for 2024+ Toyota Tacoma and Lexus GX550

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. TOYOTA TACOMA | UPPER CONTROL ARM 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.

Designed as a foundational upgrade for mid-travel suspension systems, these control arms help restore alignment geometry after lifting while maximizing droop travel and off-road articulation. Additional caster improves straight-line stability at higher speeds, while the optimized design delivers more controlled, comfortable performance on rough roads and demanding trails.
FOX engineered these upper control arms specifically for the intended vehicle platform. Fully adjustable 3/4-inch chromoly heim joints allow precise tuning of caster and camber, helping maintain proper alignment and suspension function. Stainless-steel taper misalignment spacers and 12-point steering-knuckle bolts provide a reliable, accurate fit, and the bolt-on installation requires no modification to the vehicle chassis.
Each FOX UCA is CNC machined in the USA from T6061 billet aluminum and finished with Type II anodization for enhanced corrosion resistance. A laser-etched FOX logo adds a distinctive appearance, while 1.25-inch uniballs use a hard chrome-plated ball and low-carbon steel race to promote long service life. PTFE liners, including a Kevlar fiber-reinforced liner in the heim joints, help prevent binding, reduce noise, and maintain smooth, precise operation. The aluminum arm is backed by a lifetime warranty, with a 12-month warranty covering serviceable components and finishes.
