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.

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.

Each rebuild kit includes all necessary components to replace and restore wearable parts.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

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.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.
