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 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!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!
