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.

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.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
