Unmatched Durability and Comfort for Your Bronco

Enhance your Ford Bronco’s (2021-Present) suspension with the Camp Series Rear Control Arm Set. Engineered for exceptional strength, adjustability, and durability, this set ensures a smooth on-road ride while delivering unparalleled off-road performance. It’s a significant upgrade over factory components, designed to withstand harsh terrains and daily driving demands.

Key Features Benefits

  • Heavy-Duty DOM Tubing Construction – Built with 5/16” wall thickness DOM tubing, these control arms provide exceptional strength, improved durability, and enhanced ride stability.
  • Hybrid Bushing Joint System – The axle-end features a tapered polyurethane bushing for vibration dampening and longevity, while the Johnny Joint at the adjusting end maximizes off-road articulation and flexibility.
  • Full Adjustability – Designed to accommodate lifts from 0 to 6 inches, these control arms allow for precise rear axle re-centering, pinion angle correction, and alignment adjustments for optimal performance. For lifts beyond 6 inches, custom options are available.
  • Optimized Suspension Geometry – Prevents excessive tire wear, reduces drivetrain vibrations, and enhances vehicle handling, ensuring a smooth and controlled ride.

Engineered for Strength Stability

Lifting your Ford Bronco without correcting suspension geometry can lead to handling issues and uneven tire wear. These control arms provide:

  • Precise Axle Centering – Keeps the rear axle aligned for better control and stability.
  • Corrected Pinion Angle – Reduces driveline vibrations and improves power transfer.
  • Enhanced Suspension Strength – Prevents premature wear, reducing stress on suspension components.

Durable Two-Stage Powder Coating

To ensure maximum longevity and corrosion resistance, each control arm undergoes a two-stage powder coating process: Zinc Primer Base Coat – Shields against moisture, rust, and environmental wear. Custom Top Coat Finish – Available in 10 colors, allowing you to personalize your Bronco’s suspension while adding an extra layer of protection.

Proudly Made in the USA

Manufactured in Orem, UT, the Camp Series Rear Control Arm Set is built with precision and durability in mind. By choosing CORE 4X4, you're supporting local manufacturing, high-quality American craftsmanship, and superior engineering.

Optional Hardware Upgrade

Designed for direct installation using factory hardware, these control arms can be easily mounted. However, if dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately for a secure and hassle-free installation.


  • Vehicle Fitment: Ford Bronco 21+ – Precision-engineered for all trims to enhance suspension stability, handling, and off-road performance.

  • CORE Advantage: Delivers superior strength and articulation over factory arms, reducing suspension strain and improving ride quality on any terrain.

  • Adjustability: Designed to accommodate 0–6” lifts, allowing precise pinion angle correction and axle centering for improved handling and suspension performance.

  • Construction: Made from heavy-duty 5/16” wall DOM tubing with polyurethane bushings and Johnny Joints for durability, comfort, and off-road flexibility.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.
