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.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

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.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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👌🏽
