Enhanced Suspension Performance for Your Jeep Cherokee XJ

Upgrade your Jeep Cherokee XJ with the Crawl Series Long Arm Upgrade Kit, designed to improve suspension travel, axle stability, and overall ride quality. Unlike radius-style long arms that create single points of failure, this long arm design features both long lower and upper control arms, providing superior strength, articulation, and ground clearance for off-road and on-road performance.

Key Features and Benefits

  • Long Arm Design – Enhances suspension articulation, improves ride quality, and eliminates binding issues found in short-arm setups.
  • Heavy-Duty Construction – Made from .313-inch wall DOM tubing for exceptional strength and durability in extreme conditions.
  • High-Clearance Crossmember – Improves obstacle clearance while maintaining drivetrain accessibility.
  • Adjustable for Various Lift Heights – Designed to work with lifts from 2 inches and up, making it an ideal low center of gravity (LCG) option for enhanced stability.
  • 100% Bolt-On Installation – Features bolt-on installation with optional weld surfaces for additional reinforcement.

Built for Strength and Performance

The Crawl Series Long Arm Upgrade Kit is engineered to provide maximum articulation and control. By utilizing long upper and lower control arms, this kit allows for a smoother suspension cycle, reducing driveline strain and providing superior ride comfort. Whether navigating technical rock crawls or daily commutes, this upgrade enhances handling and stability.

Optional Axle Side Upper Bushing Upgrade

While factory bushings provide adequate performance, they may wear prematurely under extreme conditions. We offer two upgrade options:

  • Polyurethane Replacement Bushings – Provides increased durability and longevity.
  • Rock Jock Axle Side Johnny Joint Upgrade Kit – Replaces factory rubber with Johnny Joints for the best articulation and longevity (cutting and welding required for installation).

Two-Stage Powder Coating for Maximum Durability

Each component undergoes a two-stage powder coating process for superior protection.

Zinc Primer Base Coat – Provides rust and corrosion resistance.

Durable Top Coat – Available in 10 custom color options to match or contrast your Jeep’s suspension.

Made in the USA

Proudly manufactured in Orem, UT, the Crawl Series Long Arm Upgrade Kit meets the highest standards of American craftsmanship. By sourcing local materials and maintaining strict quality control, we ensure premium durability and performance.


  • Vehicle Fitment: Jeep Cherokee XJ 84-01 – Transforms suspension performance with a true long-arm design, delivering unmatched stability, ride quality, and articulation for extreme off-road and on-road comfort.

  • CORE Advantage: A true 4-link design with long upper and lower control arms creates a superior suspension arc, increasing ride quality, downtravel, and articulation while reducing binding and improving axle control.

  • Adjustability: Designed for 2 to 6 inches of lift, allowing for precise alignment correction, longer suspension travel, and optimized ground clearance for low center of gravity (LCG) builds.

  • Construction: Built with 5/16” wall DOM tubing, 1/4” plate steel brackets, and a 3-piece high-clearance crossmember, featuring Johnny Joints for industry-leading articulation and 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.

  • 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 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!

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

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.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !
