Superior Comfort and Flexibility

Enhance your Ford Bronco’s suspension performance with the Camp Series Rear Upper Control Arms, designed for 2021-Present models.

These control arms provide improved ride comfort, increased off-road articulation, and exceptional durability—a significant upgrade over factory components.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 5/16” wall DOM tubing, ensuring maximum strength and durability for off-road and on-road performance.
  • Enhanced Flexibility Comfort – Features a RockJock Johnny Joint at the adjusting end and a tapered polyurethane bushing at the axle end, providing a perfect balance of articulation and ride quality.
  • Fully Adjustable for Lifted Vehicles – Allows precise pinion angle adjustments and rear axle re-centering, accommodating lifts from 0 to 6 inches.
  • Premium Two-Stage Powder Coating – Zinc primer base coat for rust prevention and a durable top coat, available in 10 color options for a custom look.

Engineered for Strength and Control

These Rear Upper Control Arms are built from 5/16”-wall DOM tubing, providing superior durability and strength compared to stock components.

The combination of Johnny Joints and polyurethane bushings delivers a smooth yet controlled ride, reducing unwanted suspension movement while allowing full articulation on rugged terrain.

Optimized for Lifted Vehicles

Lifting your Ford Bronco alters the suspension geometry, which can lead to:

  • Misalignment
  • Poor handling
  • Premature component wear

These adjustable control arms provide the solution, allowing you to:

  • Recenter the rear axle
  • Optimize pinion angle
  • Maintain proper suspension alignment

For lifts beyond 6 inches, contact us for additional options.

Durable Two-Stage Powder Coating

To maximize longevity and corrosion resistance, all Camp Series Control Arms undergo a two-stage powder coating process: Zinc Primer Base Coat – Provides a strong rust-resistant foundation. Durable Top Coat – Available in 10 color choices for custom styling and added protection.

Proudly Made in the USA

Manufactured in Orem, UT, our Camp Series Rear Upper Control Arms are 100% American-made, using locally sourced materials under strict quality control.

This ensures high-performance suspension components at a competitive price.

Optional Hardware Upgrade

Installation is simple using factory hardware.

However, for vehicles with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately.

  • Enhanced comfort
  • Improved off-road articulation
  • Precise suspension alignment

Whether you’re hitting the trails or cruising on the highway, these control arms provide superior strength and flexibility to handle any driving conditions.

Upgrade today and experience the difference!

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.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.
