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.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.
