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.

  • Adjustability: Fully adjustable for lifts from 0 to 6 inches, allowing for axle re-centering, optimized pinion and caster angles, and fine-tuned alignment for a smoother, more controlled ride.

  • 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.

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.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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!

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.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
