What’s Included in the Kit?
- Trail Series Fixed Rear Upper Control Arms (TRL-R-15-2009-FXD-RU2)
Key Features Benefits
- Built for Strength, Comfort Longevity – Constructed from high-strength steel tubing, these control arms feature a high-quality polyurethane bushing at one end and a Rock Jock Johnny Joint at the other, offering a perfect balance of articulation, durability, and NVH (Noise, Vibration, and Harshness) reduction.
- Factory-Length Design for Seamless Fit – Designed to match OEM control arm length, making them a direct replacement for factory arms, ideal for stock, leveled, or lowered setups (up to 2” drop).
- Eliminates Wheel Hop Maximizes Traction – Reduces axle movement under acceleration, preventing loss of traction and instability, especially under heavy loads or performance applications.
- Superior Handling Predictable Steering Response – Enhances suspension geometry, minimizing unwanted flex, and improving cornering precision, braking stability, and towing control.
- Recommended Pairing: For total rear axle stability, improved traction, and full suspension control, pair these upper control arms with the Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2).
Eliminate Wheel Hop Improve Ride Quality
Factory rubber bushings can create excessive preload on the axle, leading to wheel hop, instability, and inconsistent traction. The Trail Series Fixed Rear Upper Control Arms solve this by incorporating a hybrid joint design, allowing for free and controlled axle movement.
- Johnny Joint – Delivers unmatched articulation and longevity.
- Polyurethane Bushing – Effectively reduces NVH, making for a smoother, more stable ride.
When paired with our Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2), you gain full rear suspension control, ensuring your Ram 1500 stays planted, predictable, and responsive in any driving condition.
Highly Durable Two-Stage Powder Coating
Every Trail Series Control Arm undergoes a two-stage powder coating process for superior durability and corrosion resistance: Zinc primer base coat for maximum rust protection. Durable topcoat available in 10 color options to match your build.
Optional Hardware Upgrade
These control arms are designed for installation using factory hardware, but for added durability and a more secure fit, we offer an optional Grade 8 hardware kit (sold separately). This upgrade strengthens installation points and eliminates the risk of shifting under heavy loads.
