This complete set includes two upper (CRL-J-TJLJ-RU2) and two lower (CRL-J-TJLJ-RL2) control arms, designed to provide maximum articulation, improved stability, and long-term durability. Whether you're conquering rocky trails or navigating the highway, these control arms offer a significant upgrade over stock and aftermarket alternatives.

What’s Included

  • Crawl Series Rear Upper Control Arms (CRL-J-TJLJ-RU2)
  • Crawl Series Rear Lower Control Arms (CRL-J-TJLJ-RL2)

Key Features Benefits

  • Heavy-Duty Construction – The lower control arms are built from 1.75” OD x 5/16” wall DOM Tubing, while the upper control arms feature 1.5” OD x 5/16” wall DOM Tubing, offering unparalleled strength and durability over factory components.
  • Extreme Articulation – Equipped with Johnny Joints at both ends, these arms provide maximum flexibility and movement, allowing for smooth articulation over rough terrain while eliminating binding that limits suspension travel.
  • Adjustability for Lifts from 0 to 6 Inches – Easily fine-tune axle centering and pinion angle adjustments, optimizing suspension geometry for better handling, stability, and drivetrain longevity. For lifts beyond 6 inches, contact us for additional solutions.
  • Complete Rear-End Suspension Upgrade – Pairing these rear control arms with the Crawl Series Rear Track Bar creates a fully adjustable rear suspension solution, maximizing performance and ensuring precise axle alignment.

Double Adjustable Upgrade

For the ultimate convenience, we offer an optional Double Adjustable Upgrade, which equips the control arms with left- and right-hand threaded joints, allowing you to make precise on-the-vehicle adjustments. This feature enables easy alignment correction, pinion angle fine-tuning, and axle centering, eliminating the need to remove the arms during suspension adjustments.

Two-Stage Powder Coating

Every control arm undergoes a two-stage powder coating process to ensure maximum durability and corrosion resistance. The zinc primer base coat provides superior rust protection. The top coat, available in 10 color options, adds an extra layer of durability and customization.

Proudly Made in the USA

The Crawl Series Rear Control Arms Set is manufactured with pride in Orem, UT, using locally sourced materials and rigorous quality control standards. By choosing Crawl Series, you’re investing in American-made craftsmanship that’s designed to withstand the toughest conditions.

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.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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!

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
