Camp Series Rear Lower Control Arms - Compatible with Jeep Wrangler JL (CMP-J-JL-RL2)

Upgrade your Jeep Wrangler JL’s suspension with the Camp Series Rear Lower Control Arms, engineered for maximum strength, durability, and adjustability. Whether you're tackling rugged trails or cruising on the highway, these control arms enhance axle alignment, improve ride quality, and provide superior articulation over factory components. Designed for Jeep Wrangler JL model years 2018-Present, they are the perfect solution for those looking to upgrade their suspension for better control and performance.

What's Included in the Kit?

Camp Series Rear Lower Control Arms (CMP-J-JL-RL2)

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75" OD DOM tubing with a .313" wall thickness, these control arms provide exceptional durability and strength, far surpassing stock components.
  • Fully Adjustable for Lifted Vehicles – Designed to accommodate 0 to 6 inches of lift, these control arms allow for precise alignment correction and rear axle centering, essential for lifted Jeeps.
  • Johnny Joint and Tapered Polyurethane Bushing – The Johnny Joint at the adjustable end provides maximum articulation and flexibility, while the polyurethane bushing at the axle end absorbs vibrations for a smoother ride.
  • Optimized Suspension Geometry – Corrects alignment issues and pinion angle, ensuring improved handling and axle stability in both on-road and off-road conditions.
  • Recommended Pairing – For full rear-end suspension adjustability and optimal alignment, pair with our Camp Series Rear Upper Control Arms (CMP-J-JL-RU2) to fine-tune pinion angles and maximize drivability.

Designed for Lifted Vehicles

Lifting a Jeep can throw off suspension geometry, causing poor handling and uneven tire wear. The Camp Series Rear Lower Control Arms allow you to restore proper rear axle positioning, ensuring smoother handling and better stability no matter the terrain.

Durable Two-Stage Powder Coating

Every control arm undergoes a two-stage powder coating process for maximum durability and corrosion resistance. The zinc primer base coat protects against rust, while the top coat (available in 10 custom colors) lets you personalize your Jeep’s suspension setup.

Proudly Made in the USA

Manufactured in our Orem, UT facility, our Camp Series Rear Lower Control Arms are crafted with high-quality American materials, ensuring unmatched performance, longevity, and reliability.

Optional Hardware Upgrade

These control arms are designed for a straightforward bolt-on installation using factory hardware. If your bolts are rusted or worn, we offer optional Grade 8 hardware kits separately for a hassle-free install.

  • Vehicle Fitment: Jeep Wrangler JL 18+ – Precision-engineered for all trims to enhance rear axle alignment, ride quality, and articulation.

  • CORE Advantage: Improves rear axle positioning, corrects pinion angle, and enhances stability for better handling on and off-road.

  • Adjustability: Fully adjustable to accommodate 0–6” lifts, allowing precise alignment correction and optimized suspension geometry.

  • Construction: Built from 1.75” OD .313-wall DOM tubing with a Johnny Joint at the adjustable end and a polyurethane bushing at the axle end for durability and vibration control.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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.

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.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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.
