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!

 

  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Precision-engineered for all trims to enhance rear axle alignment, suspension geometry, and overall stability.

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)

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.
