Unmatched Flexibility Durability

Upgrade your Jeep Wrangler TJ/LJ (1997-2006) with the Crawl Series Rear Control Arms Set, the ultimate solution for enhanced off-road performance and superior road manners. 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.

Optional Hardware Upgrade

  • Designed for a hassle-free installation, these control arms utilize factory mounting locations and hardware.
  • For vehicles with rusted or stubborn bolts, we offer optional Grade 8 hardware kits to ensure a smooth and secure installation.

In Conclusion

The Crawl Series Rear Control Arms Set is the ultimate upgrade for Jeep Wrangler TJ/LJ owners looking for enhanced off-road flexibility, superior durability, and precise suspension control. With Johnny Joints at both ends, heavy-duty construction, and full adjustability, these control arms will transform your vehicle’s rear suspension, providing superior articulation, stability, and handling. Upgrade today and experience the unmatched performance and reliability of Crawl Series engineering!

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

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!!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!
