Fabtech’s precision-engineered geometry ensures optimal articulation and control, making it ideal for tackling challenging terrain with confidence.

Whether you’re upgrading your Jeep for rock crawling, trail riding, or heavy-duty off-road use, the JL Crawler system offers a robust, reliable solution that maintains excellent street manners while providing the strength and travel needed for extreme off-road conditions.

Key Features:

This comprehensive long arm suspension kit includes a range of components designed to work together seamlessly for improved performance and durability:

• Front and rear lower 5 Ton link arms constructed from 2" OD, .313 thick wall tubing for unmatched strength and resistance to bending
• Fabtech’s legendary 5 Ton joints with a lifetime guarantee, ensuring smooth, quiet operation on and off-road
• Full-width front crossmember that mounts the front link arms at optimal geometry and reinforces the JL’s lighter frame for rugged use
• Rear link arms attach to new frame mounts positioned for increased ground clearance and improved approach angles
• Front and rear corner-specific dual rate coil springs for balanced ride quality and articulation
• Front and rear Dirt Logic 2.25 shocks tuned for enhanced off-road damping and street comfort
• Heavy-duty flipped draglink and front shock mount brackets for improved steering geometry and durability
• Front and rear bump stop extensions, sway bar links, brake line drops, and track bar brackets included for a complete suspension upgrade

Construction & Design:

Fabtech’s JL Crawler suspension system is built with premium materials and precision engineering to withstand the rigors of off-road driving. The massive lower link arms use thick-walled steel tubing to resist bending and maintain alignment under heavy loads. The full-width front crossmember not only positions the link arms at the ideal geometry but also adds critical reinforcement to the JL’s lightweight frame, enhancing durability during aggressive trail use.

The system’s 5 Ton joints are designed for longevity and smooth articulation, eliminating the common wear issues found in lesser suspension components. Every mounting point and bracket is engineered to optimize ground clearance and suspension travel, ensuring superior handling and approach angles without compromising ride quality.

Installation & Fitment:

This suspension system fits 2018 through 2021 Jeep Wrangler JL 4-door models, including Rubicon, Sport, Sport S, Unlimited Rubicon, Unlimited Sahara, Unlimited Sport, and Unlimited Sport S trims. Installation requires welding and some exhaust modifications on all 2018 Jeep JL Wranglers; a loop delete pipe (AFE P/N 48-48024) is recommended for exhaust clearance. Additionally, upgraded driveshafts are required for 4-door models (front FTS94057, rear FTS94065).

Minor trimming or cutting of fenders may be necessary depending on tire and wheel size combinations. The system supports tire sizes up to 40x12.5R20 with high clearance fenders and appropriate wheel offsets. Professional installation is recommended to ensure proper fitment and performance.
