Enhanced Strength, Adjustability, and Off-Road Performance

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Rear Control Arm Set, engineered to provide improved durability, axle alignment, and suspension flexibility. Whether you're looking for better on-road comfort or off-road capability, this set of upper and lower control arms delivers the strength, adjustability, and articulation needed for any driving environment.

What’s Included in the Kit?

  • Rear Upper Control Arms (CMP-J-JK-RU2)
  • Rear Lower Control Arms (CMP-J-JK-RL2)

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM tubing for the lower arms and 1.5” OD DOM tubing for the upper arms, all featuring a .313" wall thickness, making them significantly stronger than factory control arms and most aftermarket alternatives.
  • Optimized Suspension Geometry – Adjustable control arms allow for precise pinion angle correction, axle centering, and alignment, crucial after installing a lift kit. Designed to accommodate 0 to 6 inches of lift.
  • Premium Joint Technology – Features Johnny Joints at the adjusting ends for unmatched articulation and tapered polyurethane bushings at the axle ends for vibration dampening and extended longevity.
  • Improved Handling and Drivability – Corrects rear axle positioning, eliminating issues caused by improper suspension alignment such as premature tire wear, instability, and drivetrain stress.
  • Recommended Pairing – For a fully optimized rear suspension, we recommend pairing this set with the Camp Series Rear Track Bar (CMP-J-JK-RTB1) to ensure complete axle centering and maximum stability.

Restore Proper Suspension Geometry and Drivability

Lifting your Jeep Wrangler JK changes the geometry of your suspension, affecting axle alignment, pinion angle, and overall drivability. Without properly adjusted control arms, your vehicle may experience rear axle misalignment, instability, and excessive drivetrain strain.

Our adjustable Rear Upper and Lower Control Arms allow you to fine-tune your suspension for optimal handling, ensuring a smooth ride, proper rear axle placement, and improved articulation. Whether you're rock crawling, towing, or daily driving, these control arms provide the stability and performance needed for a controlled, predictable ride.

Two-Stage Powder Coating for Maximum Durability

Every set of Camp Series Rear Control Arms undergoes a rigorous two-stage powder coating process for long-lasting protection against rust, corrosion, and wear: Zinc primer base coat – Adds a protective barrier against rust and environmental damage. Durable top coat in 10 color options – Personalize your Jeep’s suspension with a vibrant, long-lasting finish while adding an additional layer of defense against harsh conditions.

Proudly Made in the USA

Manufactured in our Orem, UT facility, our Camp Series Rear Control Arms are crafted to the highest standards of American engineering. We source high-quality materials locally and oversee the entire manufacturing process, ensuring superior strength, 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 Control Arm Set is a must-have upgrade for any Jeep Wrangler JK owner looking to improve rear axle alignment, drivability, and off-road capability. With heavy-duty construction, full adjustability, and premium joints, this set ensures a smoother ride, better handling, and maximum suspension performance.

Upgrade today and experience the CORE 4X4 difference in quality, durability, 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.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.
