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.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

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.

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!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

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.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

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.
