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.

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.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

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!

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.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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 ! ! !

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!
