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.

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.


  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Precision-engineered for all trims to enhance suspension control, handling, and off-road capability.

  • CORE Advantage: Enhances front suspension strength and articulation, reducing stress on components and improving ride quality on and off-road.

  • Adjustability: Fully adjustable to accommodate 0–6” lifts, allowing for precise caster correction and optimized front axle alignment.

  • Construction: Built from 1.5” OD .313-wall DOM tubing with a Johnny Joint at the adjustable end and a U-bracket for factory bushing compatibility.

  • 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.

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.

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍
