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).

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.
