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.
