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.

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

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.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

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.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!
