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.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

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.

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!

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.

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.
