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.

What's Included?

  • Long Lower Control Arms (2)
  • Long Upper Control Arms (2)
  • 1/4-Inch Plate Steel Brackets and Crossmember
  • 3-Piece High-Clearance Crossmember for Drivetrain Access

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.

In Conclusion

The Crawl Series Long Arm Upgrade Kit is the ultimate suspension upgrade for Jeep Cherokee XJ owners looking to improve stability, articulation, and ride comfort. With its long arm design, heavy-duty materials, and superior adjustability, this kit is built to handle everything from daily driving to extreme off-road adventures. Upgrade today and experience unmatched performance and durability on any terrain!

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.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

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 wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you
