Unmatched Off-Road Performance On-Road Comfort

Upgrade your Jeep Grand Cherokee ZJ with the Crawl Series Front Long Arm Upgrade Kit, engineered for superior suspension articulation, axle stability, and overall ride quality. Whether you're tackling rocky trails, high-speed desert runs, or daily driving, this long arm kit is designed to handle it all. With extended control arms, this kit optimizes suspension geometry for a smoother ride and better traction, even in extreme off-road conditions.

Key Features and Benefits

  • Heavy-Duty Construction – Built from 5/16” wall DOM tubing, these long arms provide superior durability and articulation over factory and short-arm setups.
  • Optimized Suspension Geometry – The longer control arms cycle on a longer arc, improving axle movement, reducing stress on suspension components, and enhancing ride quality.
  • Precision-Engineered Brackets – 1/4” laser-cut and precision-bent steel brackets ensure a perfect fit and unmatched strength.
  • Increased Ground Clearance Travel – Unique upper control arm bends allow for maximum up-and-down travel without body modifications.
  • Full Bolt-On Installation – No welding required—bolt-on design makes installation straightforward with included hardware.

Two-Stage Powder Coating for Maximum Protection

Every component in this kit undergoes a two-stage powder coating process for enhanced durability and corrosion resistance. Zinc primer base coat prevents rust and protects against harsh environmental conditions. Durable top coat available in 10 custom colors for added protection and personalization. Custom colors available upon request.

Proudly Made in the USA

Manufactured in Orem, UT, the Crawl Series Front Long Arm Upgrade Kit is built to the highest standards of American craftsmanship. By choosing CORE 4X4, you’re investing in high-quality, American-made products designed to withstand the most demanding conditions.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately for a hassle-free setup.


  • Vehicle Fitment: Jeep Grand Cherokee ZJ 93-98 – Upgrades your front suspension with a true 4-link long-arm design, delivering unmatched articulation, down travel, and ride quality for both on- and off-road performance.

  • CORE Advantage: Unlike radius arm designs that limit articulation and create bind, this true 4-link system allows each wheel to move independently, increasing suspension travel and maintaining stability across uneven terrain.

  • Adjustability: Extended arm geometry corrects axle positioning, optimizes caster and pinion angle, and reduces driveline vibrations—resulting in smoother handling and enhanced suspension efficiency.

  • Construction: Built from heavy-duty 5/16” wall DOM tubing, reinforced with 1/4” laser-cut plate steel brackets for maximum strength, ensuring durability in extreme conditions.

  • 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.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

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!!!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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 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!!

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!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .
