Introduction to FOX Upper Control Arms
Designed to complement FOX’s renowned coilover and shock systems, these precision-engineered control arms deliver superior strength, increased articulation, and a smoother, more controlled ride both on and off the road.
FOX UCAs aren’t just a cosmetic upgrade—they’re a performance necessity. Whether you drive a Toyota Tacoma, Tundra, Ford F-150, Chevy Silverado, or Ram 1500, FOX control arms provide the alignment correction and durability your lifted suspension needs.
The Purpose of Upper Control Arms
When a vehicle is lifted, factory upper control arms often limit suspension travel and cause improper ball joint angles, which can lead to premature wear, poor alignment, and reduced ride quality.
FOX Upper Control Arms solve these issues by:
1. Correcting ball joint and caster angles for lifted applications
2. Increasing suspension travel for better off-road articulation
3. Reducing stress on bushings and joints for longer component life
In short, they restore proper suspension geometry—keeping your FOX coilovers and shocks performing at their full potential.
Top Features and Benefits
1. Optimized for Lifted Suspension Systems
FOX UCAs are designed specifically for 1–3" lifted trucks and SUVs, ensuring proper caster correction and eliminating binding at full droop. This maximizes the usable suspension travel of your FOX shocks or coilovers.
2. Heavy-Duty Construction
Built from CNC-machined 6061-T6 billet aluminum or high-strength steel tubing, depending on model, FOX control arms deliver exceptional rigidity while remaining lightweight. Each arm is engineered to handle the rigors of off-road abuse and heavy-duty use.
3. High-Performance PTFE-Lined Spherical Bearings
FOX uses 1.25-inch stainless steel uniballs or PTFE-lined spherical bearings that offer smooth articulation with zero deflection—outperforming factory ball joints and minimizing play under load.
4. Enhanced Suspension Articulation
By improving the ball joint pivot angle and arm geometry, FOX UCAs increase wheel travel—especially when paired with FOX 2.5 Performance Elite or Factory Series coilovers. The result: a smoother, more controlled ride over uneven terrain.
5. Integrated Dust Cap Protection
Each FOX uniball features a sealed dust cap that protects the bearing from mud, sand, and road grime—extending component life and reducing maintenance.
6. Corrosion-Resistant Finishes
Arms are anodized or powder-coated for long-term durability and protection against harsh elements, maintaining performance and appearance over time.
7. Made in the USA
All FOX suspension components are proudly engineered and manufactured in the USA, ensuring premium quality and precision fitment.
Why Pair FOX UCAs with FOX Coilovers?
For optimal suspension performance, FOX Upper Control Arms are designed to work seamlessly with FOX 2.0, 2.5 Performance Elite, and Factory Series coilovers.
Together, they provide:
1. Increased wheel travel and articulation
2. Better damping control and ride smoothness
3. Improved handling and steering response
4. Reduced front-end wear on lifted vehicles
If using FOX 2.5 Performance Elite coilovers, the Dual Speed Compression (DSC) Adjusters allow independent tuning of low- and high-speed compression damping—perfect for customizing your setup for daily driving, towing, or off-roading.
Applications and Compatibility
FOX Upper Control Arms are available for a wide range of vehicles, including:
1. Toyota: Tacoma, Tundra,
2. Ford: F-150,
3. Chevrolet/GMC: Silverado 1500, Sierra 1500
4. Ram: 1500, Rebel
They are typically compatible with 1–3" lift kits, leveled suspensions, and FOX coilover systems. Always verify vehicle fitment before installation.
Frequently Asked Questions
Do I need upper control arms for a lifted truck?
Yes. UCAs are critical for correcting suspension geometry and preventing premature ball joint wear when lifting your vehicle.
Are FOX UCAs compatible with other lift brands?
Yes, most models fit common 1–3" lifts, but they’re optimized for use with FOX coilovers for maximum travel and performance.
Do FOX UCAs require maintenance?
Minimal. The sealed uniball caps protect against debris, and the PTFE liners provide self-lubrication for long-lasting smooth operation.
Are FOX suspension products made in the USA?
Yes. FOX performance suspension components are proudly engineered and manufactured in the USA.
