Enhance Your Jeep’s Suspension for Maximum Comfort and Control

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Rear Upper Control Arms, engineered to improve on-road comfort, off-road articulation, and suspension durability.

These adjustable control arms provide better axle alignment, improved handling, and reduced drivetrain stress, making them a crucial upgrade for lifted Jeeps.

What’s Included in the Kit?

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

Key Features and Benefits

  • High-Strength DOM Tubing – Constructed from 1.5” OD DOM tubing with a 5/16” wall thickness, these control arms are significantly stronger than factory components, ensuring increased durability and long-term performance.
  • Precise Axle Alignment – Adjustable design corrects rear axle positioning, reducing drivetrain strain and ensuring proper suspension geometry after lifting your Jeep.
  • Johnny Joint for Maximum Flexibility – The adjustable end features a RockJock Johnny Joint, providing exceptional articulation, reduced wear, and smoother off-road maneuverability.
  • Tapered Polyurethane Bushing – The axle end is equipped with a durable polyurethane bushing, absorbing vibrations and enhancing ride quality.
  • Optimized Suspension Geometry – Adjusts to accommodate lifts from 0 to 6 inches, preventing issues like incorrect pinion angle and excessive driveshaft wear.
  • Recommended Pairing – For optimal performance, we recommend pairing these arms with our Camp Series Rear Lower Control Arms (CMP-J-JK-RL2) to ensure proper rear axle alignment and improved stability.

Why Proper Rear Axle Alignment Matters

Lifting your Jeep Wrangler JK can throw off suspension geometry, leading to poor alignment, excessive driveshaft angles, and axle misalignment.

Without adjustable upper control arms, your pinion angle may become incorrect, causing:

  • Driveline vibrations
  • Excessive wear on U-joints
  • A rough ride

The Camp Series Rear Upper Control Arms allow you to fine-tune your axle position, ensuring your Jeep drives smoothly and efficiently while maximizing off-road articulation and traction.

Two-Stage Powder Coating for Maximum Durability

Every Camp Series Rear Upper Control Arm undergoes a rigorous two-stage powder coating process for superior corrosion resistance and longevity: Zinc primer base coat – Provides a barrier against rust, road salt, and harsh environmental elements. Durable top coat in 10 color options – Adds long-lasting protection and allows you to customize your Jeep’s suspension to match your build.

Proudly Made in the USA

Manufactured in our Orem, UT facility, our Camp Series Rear Upper Control Arms are crafted with American-made quality and precision.

We use locally sourced materials and oversee the entire production process to ensure every part meets our high standards for durability and performance.

Optional Hardware Upgrade

Designed for easy installation using factory hardware, but if your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth installation.

In Conclusion

The Camp Series Rear Upper Control Arms are an essential upgrade for Jeep Wrangler JK owners looking to:

  • Correct rear axle alignment
  • Improve ride quality
  • Enhance off-road performance

With heavy-duty construction, full adjustability, and premium joint technology, these control arms ensure a smoother ride, better suspension articulation, and maximum durability.

Upgrade today and experience the CORE 4X4 difference in quality, performance, and American craftsmanship!

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 ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.
