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 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!

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.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

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've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you
