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.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

The quality and durability of the arms are the best. They are super heavy duty. And lifetime warranty is crazy

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 :) .

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!
