Dial in Your Pinion Angle for a Smoother, More Controlled Ride
Fine-tune your Ram 1500 (2009–Present) with the Track Series Adjustable Rear Upper Control Arms, engineered to correct pinion angle, reduce driveline vibration, and optimize rear axle alignment. Whether you're daily driving, towing, or off-roading, these arms allow for on-the-fly adjustments, keeping your drivetrain smooth and suspension geometry precise.
Key Features Benefits
- Heavy-Duty DOM Tubing Construction – Built from 1.75" OD .313" wall DOM tubing, providing maximum strength and durability for high-performance applications.
- Rock Jock Johnny Joints at Both Ends – Fully serviceable and rebuildable, offering unmatched articulation, eliminating suspension bind, and reducing strain on driveline components.
- Left- Right-Hand Threaded Adjustability – Easily adjust pinion angle while installed, ensuring driveline alignment to prevent vibration and premature wear.
- Recommended Pairing for Complete Rear Suspension Control – While these upper control arms adjust pinion angle and driveline vibration, eliminating wheel hop requires upgrading the lower control arms. Pair these with the Track Series Adjustable Rear Lower Control Arms (TRK-R-15-2009-RL2) for full control over rear axle positioning, traction, and power transfer.
Fine-Tune Pinion Angle Reduce Driveline Vibration
Factory control arms lack adjustability, leading to misalignment, increased stress, and vibration—especially when modifying ride height. The Track Series Adjustable Rear Upper Control Arms allow precise adjustments to pinion angle, eliminating unnecessary strain on driveshafts and rear axle components, ensuring a smoother, more efficient power transfer.
Highly Durable Two-Stage Powder Coating
Zinc primer base coat for maximum corrosion resistance Durable topcoat available in 10 color options for a customized look
Optional Hardware Upgrade
Designed for installation using factory hardware, but for enhanced durability and a stronger fit, we offer an optional Grade 8 hardware kit (sold separately).
Proudly Made in the USA
Manufactured in Orem, UT, every CORE 4X4 component meets strict quality control standards for precision, strength, and long-term durability.
Final Thoughts
The Track Series Adjustable Rear Upper Control Arms provide the precision needed to dial in pinion angle, eliminate driveline vibration, and enhance rear suspension performance. For complete control over rear axle movement and to fully eliminate wheel hop, pair these with the Track Series Adjustable Rear Lower Control Arms (TRK-R-15-2009-RL2).
