Take Your Ram 1500’s Rear Suspension to the Next Level

Designed for aggressive performance on both the track and off-road terrain, the Race Series Complete Rear Control Arm Set ensures superior stability, precise axle control, and unmatched durability. Whether you're launching off the line, tackling technical trails, or daily driving, these control arms deliver exceptional handling and responsiveness.

Key Features Benefits

  • Maximum Axle Control Stability – Maintains precise rear axle positioning, improving handling, traction, and overall ride quality.
  • Lightweight 7075 Aluminum Construction – Built from aircraft-grade aluminum for exceptional strength while reducing weight to improve performance.
  • Fully Adjustable for Pinion Angle Axle Centering – Fine-tune suspension geometry for optimal drivetrain alignment, preventing premature wear and improving ride comfort.
  • Rock Jock 4x4 Johnny Joints – High-misalignment joints at both ends provide superior articulation, durability, and long-lasting performance.

Recommended Pairing

Enhance suspension performance by adding the Race Series Rear Panhard Track Bar (RC-R-15-2009-RPTB1) for full rear-end control.

Performance-Driven Suspension Upgrade

Lifting or lowering your truck can throw off axle alignment, leading to handling instability, increased component wear, and poor ride quality. The Race Series Complete Rear Control Arm Set eliminates these issues, allowing for precise rear axle centering, improved pinion angle adjustments, and a more planted feel, whether you’re on-road or off-road.

Two-Stage Powder Coating

Choose our two-stage powder coating for exceptional corrosion resistance, starting with a zinc primer base followed by a durable topcoat in your preferred color. For those who prefer the raw, high-performance look, opt for the uncoated aluminum finish to showcase the strength of 7075 aluminum.

Made in the USA

Proudly designed and manufactured in Orem, UT, this kit reflects our commitment to American craftsmanship, rigorous quality control, and industry-leading durability. Every component is built to outlast and outperform stock suspension parts.

Optional Hardware Upgrade

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

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.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

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!
