Ultimate Off-Road Performance

Upgrade your Jeep Wrangler JL with the Crawl Series Complete Set of Control Arms, designed for superior flexibility and durability while maintaining excellent road manners. This 8-piece set provides unmatched strength, articulation, and adjustability, outperforming all other aftermarket options. Whether tackling rugged trails or cruising the highway, this upgrade enhances handling, axle alignment, and overall suspension geometry.

Key Features and Benefits

  • Heaviest tubing for upper and lower control arms – Lower control arms are constructed from 1.75” OD DOM tubing with a 5/16” wall thickness, while upper control arms use 1.5” OD DOM tubing with the same robust wall thickness for maximum durability.
  • Johnny Joints for superior flexibility – Each control arm is equipped with Johnny Joints at both ends for unmatched articulation and longevity. The front upper control arms feature a U-bracket at the axle end, attaching to the factory-installed bushing.
  • Adjustable for lift heights from 0 to 6 inches – Enables precise alignment correction, axle centering, and pinion angle optimization to eliminate driveline vibrations.
  • Recommended pairing – When all 8 control arms work in sync, your suspension is fully dialed in for improved handling and off-road capability.

Durable Powder Coating for Maximum Protection

Every control arm undergoes a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat enhances rust protection, while the top coat—available in 10 color options—provides long-lasting resilience and customization.

Proudly Made in the USA

The Crawl Series reflects the highest standards of American manufacturing. Built in Orem, UT, using locally sourced materials, every component undergoes rigorous quality control to ensure maximum strength, reliability, and longevity.

Optional Hardware Upgrade

This kit is designed for straightforward installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately to ensure a seamless setup.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

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!!
