Performance, Strength, and Stability
Upgrade your Dodge Ram 5500 (2008-2020) with our Adjustable Front Upper Control Arms, designed to refine caster and pinion angles for improved handling, ride quality, and suspension durability. When lifting your truck, improper caster angles can lead to wandering steering, rough tracking, and instability—our control arms correct these issues, restoring confident handling on and off the road.
Built specifically for heavy-duty applications, these control arms are engineered for towing, hauling, and commercial-use trucks, providing exceptional strength without compromising ride comfort. When paired with our Adjustable Front Lower Control Arms, they allow for precise axle positioning, including pushing the front axle forward (commonly referred to as “the stretch”), enabling larger tire fitment without fender liner interference.

- On-Vehicle Adjustability for Precision Alignment – Left-hand and right-hand threaded adjusters allow for fine-tuning caster and pinion angle without removal, ensuring perfect alignment correction for 0 to 6 inches of lift.
- Optimized for Larger Tires Improved Steering Stability – Allows for pushing the front axle forward (“the stretch”) to run larger tires without rubbing the rear of the fender liner, improving clearance and functionality.
- Recommended Pairing – For complete front-end alignment and suspension control, pair with Adjustable Front Lower Control Arms (D-55-2008-FL2) for full axle recentering, optimal caster correction, and enhanced tire clearance.
Optimized Suspension Performance
Our Adjustable Front Upper Control Arms play a crucial role in restoring caster alignment, eliminating wandering at highway speeds, and improving steering response. When paired with Front Lower Control Arms, they allow for full axle recentering, reducing stress on suspension components and enhancing overall ride comfort and stability.
For lifted trucks used in towing and hauling, proper caster correction significantly improves handling under load, preventing excessive front-end drift or tire wear.
Two-Stage Powder Coating
To maximize durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides superior rust prevention. Durable top coat – Available in 10 colors to match your truck’s aesthetics while ensuring long-lasting protection.
Made in the USA
Manufactured in Orem, UT, our control arms are built with American-sourced materials, ensuring rigorous quality control and unmatched reliability. Supporting American manufacturing means investing in superior craftsmanship and long-lasting performance for work and off-road applications.
Optional Hardware Upgrade
These control arms install using factory hardware, but for rusted or stubborn bolts, we offer Grade 8 hardware kits, available separately, for a hassle-free installation.
In Conclusion
Upgrading to Adjustable Front Upper Control Arms means investing in better alignment, enhanced stability, and long-term durability. Pair them with Front Lower Control Arms for a complete front suspension upgrade, improving handling, eliminating steering instability, and optimizing caster for a smoother ride and superior off-road capability.
