Upgrade Your Jeep’s Suspension for Superior Comfort and Control

Enhance your Jeep Wrangler JL (2018-Present) with the Camp Series Rear Upper Control Arms, engineered to provide improved ride comfort, optimized suspension geometry, and long-lasting durability. Whether you're tackling off-road trails or cruising the highway, these control arms offer a significant upgrade over factory components, ensuring superior axle alignment and stability.

What’s Included in the Kit?

  • Camp Series Rear Upper Control Arms (CMP-J-JL-RU2)

Key Features and Benefits

  • Engineered for Strength – Constructed from 1.5” OD DOM Tubing with 5/16” wall thickness, these control arms offer exceptional durability compared to factory components.
  • Optimized Suspension Geometry – Adjustable design allows for precise alignment correction and rear axle re-centering, essential after installing a lift.
  • Premium Joint Technology – Features a Johnny Joint at the adjusting end for superior articulation and a tapered polyurethane bushing at the axle end to reduce vibration and enhance longevity.
  • Recommended Pairing – For optimal rear suspension performance, pair these control arms with our Camp Series Rear Lower Control Arms (CMP-J-JL-RL2) for complete rear-end stability and alignment correction.

Precision Adjustability for Lifted Vehicles

Lifting your Jeep Wrangler JL alters the factory suspension geometry, which can lead to misalignment, premature tire wear, and reduced stability.

Our adjustable rear upper control arms allow you to fine-tune your pinion angle and reposition your rear axle to maintain optimal handling and drivability.

  • Designed to accommodate lifts from 0 to 6 inches for maximum suspension flexibility.
  • For lifts beyond 6 inches, contact us for custom solutions.

Two-Stage Powder Coating for Maximum Durability

Each control arm undergoes a two-stage powder coating process for superior protection against rust and corrosion. Zinc primer base coat ensures a strong barrier against environmental damage. Durable top coat, available in 10 color options, allows for customization while maintaining long-term durability.

Proudly Made in the USA

At CORE 4X4, we are committed to American manufacturing quality. Our Camp Series Rear Upper Control Arms are proudly designed and built in Orem, UT, using high-quality materials sourced locally.

By choosing CORE 4X4, you're investing in precision engineering, reliability, and superior craftsmanship.

Straightforward Installation

Designed for easy installation using factory hardware, these control arms bolt directly into place without modification.

  • If your factory bolts are rusted or damaged, we offer optional Grade 8 hardware kits separately to ensure a smooth installation process.

In Conclusion

Upgrading to Camp Series Rear Upper Control Arms gives your Jeep Wrangler JL superior axle alignment, enhanced articulation, and increased suspension flexibility.

Whether you're looking for better on-road comfort or off-road durability, these control arms provide the strength and adjustability needed to keep your Jeep performing at its best.

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

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.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.
