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!

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.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!
