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).

Upgrade today for smoother operation and total suspension control!

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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.

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.

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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!
