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.

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👌🏽

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

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.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.
