Fabtech Crawler Long Arm Coil Suspension System
2007–2018 Jeep Wrangler JK / Wrangler Unlimited
K4058M
Overview:
The Fabtech Crawler 3-inch long arm coil suspension system is engineered specifically for 4-door Jeep Wrangler JK models from 2007 through 2018. Designed to enhance off-road capability and suspension articulation, this system replaces all eight factory link arms with extended length, heavy-duty units that allow for smooth operation at extreme angles. Ideal for Jeep enthusiasts seeking improved ground clearance, durability, and ride quality, the Crawler system maintains factory load carrying capacity while providing a robust 3-inch lift.
Featuring Fabtech’s innovative Stealth shocks, this suspension upgrade delivers superior damping performance for both on- and off-road conditions. Whether tackling rugged trails or daily driving, the Crawler system offers a balanced combination of strength, articulation, and comfort tailored to the Jeep Wrangler JK platform.

Fabtech’s Crawler system incorporates advanced engineering and premium components to ensure long-lasting performance and reliability:
- Complete replacement of all eight link arms with extended length, high-clearance units
- Link arms mounted high on the frame to maximize ground clearance without bending
- Lower links constructed from 2" OD, .313 thick wall DOM steel for exceptional strength
- Internally threaded link arms designed to accept Fabtech’s patented 5 Ton Joint, guaranteed never to wear out
- Weld-on 1/4" thick steel track bar brackets front and rear for proper roll center and durability
- Standard single-rate coil springs retain factory load carrying capacity and provide balanced suspension performance
- Includes Fabtech Stealth shocks for improved ride control and damping
- Compatible with a wide range of tire and wheel sizes, including up to 37" tires with minor trimming or cutting
Construction & Design:
Fabtech’s Crawler suspension system is built with premium materials and precision engineering to withstand the rigors of serious off-road use. The lower link arms are fabricated from heavy-duty DOM steel tubing, featuring a thick wall for maximum resistance to bending and impact. Fabtech backs this strength with a warranty against bending, underscoring their confidence in the durability of these components.
The system’s internally threaded link arms accommodate Fabtech’s revolutionary 5 Ton Joint, a high-strength spherical bearing designed to eliminate wear and provide long-lasting articulation. Weld-on steel track bar brackets ensure proper suspension geometry and roll center alignment, preventing failure under extreme conditions. The coil springs are engineered to maintain factory load ratings, ensuring that ride quality and handling remain balanced even with the lift.
Installation & Fitment:
Installation of the Fabtech Crawler system requires welding, making professional installation highly recommended. For 2012–2018 Jeep Wrangler models, exhaust modification is necessary, specifically the Fabtech loop delete pipe (FTS94060). Additionally, driveshaft replacements are required for 4-door models: front driveshaft (FTS94057) and rear driveshafts (FTS94052 for 2007–2011, FTS94059 for 2012–2018).
The system is compatible with Jeep Wrangler JK and Wrangler Unlimited models from 2007 through 2018, including Rubicon, Sahara, Sport, Sport S, X, and special anniversary editions. Tire fitment ranges from 35" to 37" with appropriate wheel offsets and minor trimming or cutting of fenders as needed.
