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.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

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.
