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.


  • Vehicle Fitment: Jeep Cherokee XJ 84-01, Jeep Comanche MJ 86-92 – Improves axle control, enhances front-end stability, and ensures consistent handling for lifted Jeeps.

  • CORE Advantage: Corrects caster angle for better steering precision, reducing wandering while maintaining the flexibility needed for off-road articulation.

  • Adjustability: Designed for lifts from 0 to 6 inches, allowing precise axle alignment, optimizing pinion angle, and improving overall suspension geometry.

  • Construction: Heavy-duty 1.5” OD 5/16” wall DOM tubing, Johnny Joint at the adjusting end, and a ¼” U-bracket at the axle end for maximum durability and smooth suspension movement.

  • 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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.
