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.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!
