Enhanced Suspension Control for Unrivaled Performance

Upgrade your Jeep Cherokee XJ (1984-2001) and Jeep Comanche MJ (1986-1992) with the Crawl Series Front Upper Control Arms, designed to improve axle stability, handling, and suspension articulation. Whether you're tackling rugged off-road terrain or enjoying a smooth highway drive, these control arms enhance your vehicle's strength, flexibility, and durability.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.5" OD .313" wall DOM tubing, delivering unmatched durability and strength for extreme off-road conditions.
  • Johnny Joint for Maximum Flexibility – Features a Johnny Joint at the adjusting end, allowing for smooth articulation, reduced bushing bind, and greater suspension travel.
  • Secure Axle Connection – Equipped with a 1/4-inch U-bracket at the axle end, ensuring a solid connection to the factory axle-mounted bushing for long-lasting reliability.
  • Recommended Pairing – For a complete suspension upgrade, pair these upper control arms with the Crawl Series Front Lower Control Arms (CRL-J-XJMJ-FL2) to maximize axle stability and handling precision.

Two-Stage Powder Coating for Maximum Protection

To ensure long-lasting durability and corrosion resistance, each control arm undergoes a two-stage powder coating process. A zinc primer base coat provides superior rust protection, while the top coat—available in 10 color options—adds an extra layer of defense and customization.

Proudly Made in the USA

Manufactured in Orem, UT, the Crawl Series Front Upper Control Arms are built to the highest standards of American craftsmanship, ensuring superior quality, strength, and long-term durability.

Optional Hardware Upgrade

Designed for straightforward bolt-on installation, these control arms utilize factory hardware for a hassle-free setup. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately for a seamless installation.

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!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

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!!

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
