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.

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.


  • Vehicle Fitment: Jeep Wrangler TJ LJ 97-06 – A complete rear suspension upgrade that enhances articulation, improves axle alignment, and eliminates driveline vibrations caused by improper pinion angles in lifted setups.

  • CORE Advantage: Johnny Joints at both ends allow for maximum articulation, ensuring smooth suspension movement while preventing bind that limits flex and reduces traction on rugged trails.

  • Adjustability: Accommodates lifts from 0 to 6 inches, enabling precise axle centering and pinion angle correction to reduce driveline vibrations. Upgrade to double adjustability for quick, on-the-vehicle fine-tuning.

  • Construction: Lower control arms use 1.75” OD x 5/16” wall DOM tubing, while uppers feature 1.5” OD x 5/16” wall DOM tubing, providing extreme durability and long-term reliability for off-road abuse.

  • 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.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

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!!

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!

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.

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.

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!
