Product Details

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 want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

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.
