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.

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.

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

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

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.

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.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.
