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.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!
