Unmatched Off-Road Performance On-Road Comfort

Upgrade your Jeep Grand Cherokee ZJ with the Crawl Series Rear Long Arm Upgrade Kit, engineered to maximize suspension travel, axle stability, and ride quality. Designed for aggressive off-road performance and smooth highway driving, this kit transforms your ZJ’s suspension geometry, improving articulation and eliminating binding, even in extreme conditions.

Key Features and Benefits

  • Heavy-Duty Construction – Built from 5/16” wall DOM tubing, these long arms deliver exceptional strength and articulation compared to factory and short-arm setups.
  • Optimized Suspension Geometry – The longer control arms allow for a smoother, more controlled axle range of motion, improving traction and reducing stress on suspension components.
  • Precision-Engineered Brackets – 1/4” laser-cut and precision-bent steel brackets ensure a perfect fit and rock-solid durability.
  • Increased Ground Clearance Travel – Allows for maximum articulation without limiting suspension movement.
  • Full Bolt-On Installation – No welding required—bolt-on design makes installation straightforward with included hardware.

Two-Stage Powder Coating for Maximum Protection

Each component in this kit undergoes a two-stage powder coating process for long-lasting 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.

Made in the USA

Manufactured in Orem, UT, the Crawl Series Rear 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.


  • Vehicle Fitment: Jeep Grand Cherokee ZJ 93-98 – A rear long-arm suspension transformation that enhances articulation, axle stability, and ride quality, making your ZJ unstoppable on and off the trail.

  • CORE Advantage: This true 4-link rear long-arm system eliminates the binding and limitations of short-arm setups, allowing for smoother suspension movement, increased down travel, and enhanced off-road flexibility.

  • Adjustability: Corrects pinion angle, reduces driveline vibrations, and ensures proper axle alignment at all lift heights (0–6 inches), optimizing both off-road performance and on-road handling.

  • Construction: Heavy-duty 5/16” wall DOM tubing combined with precision-engineered 1/4” plate steel brackets for maximum durability, ensuring reliability 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.

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!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.
