Designed for Jeep Wrangler JL model years 2018-Present, this set provides adjustability, superior strength, and enhanced ride quality, making it the perfect upgrade over stock control arms.

What's Included in the Kit?

  • Camp Series Rear Upper Control Arms (CMP-J-JL-RU2)
  • Camp Series Rear Lower Control Arms (CMP-J-JL-RL2)

Key Features and Benefits

  • Heavy-Duty Construction – Built from 1.75" OD DOM tubing with .313" wall thickness on the lower control arms and 1.5" OD DOM tubing with .313" wall thickness on the upper control arms, providing superior strength over factory components.
  • Optimized Suspension Geometry – Fully adjustable control arms allow for precise axle positioning, pinion angle adjustments, and suspension correction, accommodating lifts from 0 to 6 inches.
  • Premium Joint Technology – Features Johnny Joints at the adjusting ends for superior articulation and tapered polyurethane bushings at the axle ends for vibration dampening and extended longevity.
  • Recommended Pairing – For a complete rear suspension solution, pair this kit with our Camp Series Rear Track Bar (CMP-J-JL-RTB1) to further improve stability and axle alignment.

Enhanced Control and Suspension Performance

This fully adjustable rear control arm set is designed to restore proper suspension geometry, correct alignment after lifting, and maximize handling for both on-road driving and off-road adventures. Whether you're tackling rough terrain or cruising on the highway, these control arms enhance ride quality, prevent premature tire wear, and improve suspension articulation.

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.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

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.
