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!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!
