Upgrade your Jeep Wrangler JK with the Crawl Series Complete Set of Control Arms, the ultimate solution for superior off-road flexibility and on-road comfort. Engineered for strength, durability, and precision, this comprehensive kit surpasses all other aftermarket options, delivering unmatched performance and reliability for your off-road adventures.

What’s Included in the Kit?

  • Crawl Series front upper control arms – CRL-J-JK-FU2
  • Crawl Series front lower control arms – CRL-J-JK-FL2
  • Crawl Series rear upper control arms – CRL-J-JK-RU2
  • Crawl Series rear lower control arms – CRL-J-JK-RL2

Key Features and Benefits

  • Engineered construction – Lower control arms are made with 1.75” OD DOM tubing and 5/16” wall thickness for maximum durability, while upper control arms are constructed with 1.5” OD DOM tubing and 5/16” wall thickness for optimal strength.
  • Johnny Joints for extreme flexibility – Equipped with Johnny Joints at both ends, these control arms provide exceptional articulation and longevity. The front upper control arms feature a U-bracket at the axle end, seamlessly integrating with the factory-installed bushing.
  • Enhanced adjustability – Designed for effortless adjustability, accommodating lifts from 0 to 6 inches, allowing for precise alignment correction, front and rear axle re-centering, and pinion angle optimization to reduce driveline vibrations.
  • Recommended pairing – When used as a complete set, the synchronization of all 8 control arms maximizes performance and ensures your suspension is dialed in for any terrain.

Two-Stage Powder Coating for Durability

Each control arm undergoes a meticulous two-stage powder coating process. A zinc primer base provides superior corrosion resistance, while the durable top coat, available in 10 custom color options, adds extra protection and style. This process ensures long-lasting durability, even in the most demanding environments.

Proudly Made in the USA

The Crawl Series reflects the highest standards of American manufacturing. Produced in our Orem, UT facility, every component undergoes rigorous quality control, from sourcing local materials to final assembly. By choosing the Crawl Series, you support American craftsmanship while receiving a product engineered to excel.

Optional Hardware Upgrade

Designed for straightforward installation using factory hardware, this kit makes upgrading your suspension hassle-free. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available for purchase to ensure a smooth setup.

Whether you're navigating rocky trails or cruising on the highway, this kit delivers unmatched performance and handling. Upgrade today and take full control of your Jeep’s suspension!

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.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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!!!
