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.

  • CORE Advantage: Corrects caster angle issues caused by lifting, eliminating wandering and unstable steering, improving high-speed stability, and ensuring a confident driving experience on and off the road.

  • 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.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

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 purchased a upper and lower set of control arms from core 4x4 they came early then expected and seem to be very nice quality I ran into a complication installing them and emailed them my question I was expecting to get the response maybe the next day because it was after hours I got a response in about a few minutes which allowed me to finish the project that day I super appreciate that, the products are good strong lifetime warranty and their customer service is top notch

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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!
