Unmatched Strength, Stability, and Adjustability

Elevate your 2021-Present RAM TRX’s performance with the CORE 4X4 7075 Aluminum Rear Upper Control Arms (R-TRX-2021-AL-RU2)—a premium suspension upgrade crafted for the ultimate off-road experience. Built to dominate high-speed desert racing, rocky trails, and anything else you can throw at it, these arms add precision handling, superior strength, and perfect axle alignment to an already formidable truck. If you’re looking for an elite component that matches the TRX’s unmatched prowess, these rear upper control arms deliver the goods.

Key Features and Benefits

  • Heavy-Duty 7075 Aluminum Construction – Fabricated from 2.5” OD 7075 aluminum for maximum strength, corrosion resistance, and weight savings over traditional steel.
  • Massive 3.0” Rock Jock Johnny Joints – Built with fully greaseable, rebuildable 1.5” threaded joints for unparalleled durability, flexibility, and articulation in punishing off-road conditions.
  • On-Vehicle Adjustability for Precision Alignment – Left-hand and right-hand threaded adjusters enable quick fine-tuning of axle position and pinion angles without arm removal.
  • Engineered for Extreme Off-Road Desert Racing – Delivers superior tracking, reduced tire wear, and remarkable ride quality under the most intense, high-speed performance demands.

Recommended Pairing

For a fully optimized rear suspension setup, pair these upper arms with the CORE 4X4 7075 Aluminum Rear Lower Control Arms (R-TRX-2021-AL-RL2) to maximize stability and control.

Performance-Driven Engineering for Maximum Control

Our 7075 aluminum rear upper control arms are expertly designed to correct factory shortcomings, improve traction, and handle extreme load demands. These arms provide smoother suspension travel and minimize stress on bushings and mounts. They offer on-the-fly adjustability for perfect pinion angles and axle centering while delivering unmatched resilience in high-speed desert runs, crawling over challenging terrains, or towing heavy loads. This isn’t just an upgrade—it’s the definitive step toward unlocking your RAM TRX’s off-road supremacy and preserving long-term reliability.

Two-Stage Powder Coating for Maximum Durability

To protect against corrosion and harsh environmental conditions, each aluminum component undergoes a rigorous two-stage powder coating process. Each part receives a zinc primer base coat to ensure lasting rust protection, followed by a top coat available in 10 colors so you can match your truck’s aesthetic and maintain a premium finish.

Proudly Made in the USA

Manufactured in Orem, UT, our CORE 4X4 7075 Aluminum Rear Upper Control Arms use American-sourced materials and meet strict quality standards. By supporting American-made products, you invest in top-tier craftsmanship and dependable performance.

In Conclusion

The CORE 4X4 7075 Aluminum Rear Upper Control Arms are the premier suspension upgrade for discerning RAM TRX owners who demand superior control, unrivaled strength, and absolute adjustability. By replacing vulnerable stock components with aircraft-grade 7075 aluminum, you secure a performance boost that keeps your off-road machine ready for the most extreme conditions.

Equip your RAM TRX with these upper control arms and unleash its full potential—because your truck deserves only the best.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!
