Ultimate Flexibility and On-Road Comfort

Elevate your Jeep Wrangler TJ/LJ (1997-2006) with the Crawl Series Front Control Arms Set. Engineered to deliver unmatched off-road performance and superior on-road comfort, this set includes a pair of Front Upper Control Arms and Front Lower Control Arms. Designed for enthusiasts who demand precision, flexibility, and durability, these control arms offer a significant performance upgrade over factory and competitor components.

Key Features and Benefits

  • Unparalleled Flexibility – Featuring Johnny Joints at all connection points, these control arms allow for maximum articulation, ensuring smooth suspension travel and exceptional off-road performance.
  • Precision Adjustability – Designed to accommodate lifts from 0 to 6 inches, these control arms enable precise alignment correction, axle re-centering, and optimized pinion and caster angles.
  • Enhanced Durability – Constructed from heavy-duty DOM tubing—1.75" OD for the lowers and 1.5" OD for the uppers—each control arm is built to withstand extreme off-road conditions while maintaining reliability and strength.
  • Complete Suspension Solution – Pair these control arms with our Crawl Series Front Track Bar for a fully dialed-in front suspension system that ensures optimal alignment and stability.

Engineered for Precision and Strength

The lower control arms are constructed from 1.75” OD DOM Tubing with a robust 5/16” wall thickness, while the upper control arms utilize 1.5” OD DOM Tubing with the same impressive wall thickness. These materials far exceed industry standards for durability and performance. The Johnny Joints at both ends provide unmatched articulation and longevity, ensuring your suspension can handle the toughest trails while maintaining a smooth ride on the highway.

Two-Stage Powder Coating for Maximum Protection

Our control arms undergo a rigorous two-stage powder coating process to ensure superior corrosion resistance and durability. A zinc primer base coat protects against rust, while a top coat, available in 10 vibrant colors, adds a personalized touch and further safeguards your investment.

Proudly Made in the USA

Manufactured in Orem, UT, the Crawl Series represents the finest in American engineering. By sourcing materials locally and maintaining strict quality control, we ensure every product meets the highest standards of craftsmanship and performance.

Optional Hardware Upgrade

The Crawl Series Front Control Arms Set is designed for a straightforward installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately to make the process seamless.


  • Vehicle Fitment: Jeep Wrangler TJ/LJ 97-06 – Improves front suspension geometry for enhanced handling, stability, and axle positioning, delivering precise steering response and better control.

  • Construction: Heavy-duty DOM tubing—1.75” OD for lowers and 1.5” OD for uppers—with a 5/16” wall thickness, featuring Johnny Joints at all ends for superior articulation, reduced suspension bind, and long-term durability.

  • 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.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

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!!!

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you
