Enhanced Suspension Performance and Alignment

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Front Upper Control Arms, designed to restore proper alignment, improve handling, and enhance off-road articulation. Whether tackling rugged trails or maintaining highway drivability, these control arms provide superior strength, adjustability, and durability, ensuring a smoother and more controlled ride.

What's Included in the Kit?

  • Camp Series Front Upper Control Arms (CMP-J-JK-FU2)

Key Features and Benefits

  • Precision Suspension Alignment – Helps correct caster angle and re-center the front axle after a lift, preventing steering instability and improving overall handling.
  • Heavy-Duty DOM Tubing Construction – Built from 1.5" OD DOM tubing with a .313" wall thickness, making these control arms significantly stronger than factory components.
  • Advanced Joint Technology – Features a Johnny Joint at the adjustable end for unmatched articulation and flexibility, while the axle end connects via a U-bracket to the factory bushing, maintaining seamless compatibility.
  • Adjustability for Lifted Vehicles – Fully adjustable to accommodate 0 to 6 inches of lift, allowing for precise caster correction and front axle alignment. For lifts beyond 6 inches, please contact us for additional options.
  • Recommended Pairing – For a complete front-end suspension solution, we recommend pairing these control arms with our Camp Series Front Lower Control Arms (CMP-J-JK-FL2) to fully optimize steering alignment and caster correction.

Correcting Caster for Improved Steering Stability

One of the most critical aspects of suspension geometry is caster angle, which directly affects your Jeep’s steering stability and control. Improper caster—often caused by lifting your vehicle—can result in wandering, unpredictable steering, and excessive following of road ruts. By adjusting the front upper control arms, you can restore the proper caster angle, ensuring a smoother, more predictable driving experience on highways and improved control in off-road conditions.

Two-Stage Powder Coating

Our dual-layer powder coating process ensures exceptional durability and corrosion resistance. Zinc primer base coat protects against rust and corrosion. Top coat, available in 10 colors, provides additional protection and allows you to customize your suspension components.

Made in the USA

Proudly manufactured in Orem, UT, our Camp Series Front Upper Control Arms are built with locally sourced materials and crafted under strict quality standards. Supporting American manufacturing means investing in superior craftsmanship and long-lasting durability.

Optional Hardware Upgrade

This kit is designed for easy installation using factory hardware. If your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a seamless installation process.

In Conclusion

The Camp Series Front Upper Control Arms provide essential caster correction, enhanced durability, and improved articulation, making them a must-have upgrade for lifted Jeep JK owners. Designed for maximum performance on and off the road, these control arms help restore proper alignment, ensuring stability, precise steering, and a more enjoyable driving experience. Upgrade today and take full control of your Jeep’s suspension!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

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.
