Fabtech Crawler 3in Long Arm Coil Suspension System

2007–2017 Jeep Wrangler / 2018 Jeep Wrangler JK

K4058DL

Overview:

The Fabtech Crawler 3-inch Long Arm Coil Suspension System is engineered to elevate your Jeep Wrangler’s off-road capability and on-road performance. Designed specifically for 2007–2017 Jeep Wrangler models and the 2018 Jeep Wrangler JK, this comprehensive suspension upgrade replaces all eight link arms with extended length units, allowing for smooth articulation at extreme angles. Ideal for off-road enthusiasts seeking enhanced ground clearance, improved suspension geometry, and durable components, the Crawler system delivers a balanced ride without sacrificing factory load carrying capacity.

Featuring Fabtech’s Dirt Logic 2.25 non-reservoir shocks, this system provides reliable damping performance tailored for rugged terrain. Whether tackling rocky trails or daily driving, the Crawler system ensures your Jeep maintains control, comfort, and durability.

Key Features:

Fabtech’s Crawler suspension system incorporates advanced engineering and premium materials to deliver superior off-road performance and reliability. Key features include:

• Complete replacement of all eight link arms with extended length units for improved suspension articulation
• High-mounted link arms on the frame to increase ground clearance without bending, unlike other long arm systems
• Lower links constructed from 2" OD, .313 thick wall DOM steel, backed by a warranty against bending
• 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 for proper roll center alignment front and rear
• Standard single-rate coil springs that retain factory load carrying capacity and provide balanced suspension performance
• Includes Dirt Logic 2.25 non-reservoir shocks optimized for this lift system
• Supports tire sizes up to 37x12.50R20 with minor trimming or cutting depending on wheel and fender configuration

Construction & Design:

Fabtech’s Crawler system is built with durability and precision in mind. The link arms utilize heavy-duty DOM steel tubing with thick walls to resist bending and withstand harsh off-road conditions. The internally threaded design accommodates Fabtech’s 5 Ton Joints, which are engineered for longevity and smooth articulation without wear. The high-mounting position of the link arms on the frame enhances ground clearance, reducing the risk of damage from rocks and obstacles.

Track bar brackets are fabricated from 1/4" thick steel and welded on to ensure a secure, fail-safe connection that maintains proper suspension geometry and vehicle stability. The coil springs are designed as a single-rate setup, balancing ride comfort with load capacity to maintain factory performance standards.

Installation & Fitment:

Installation of the Fabtech Crawler system requires welding, making professional installation recommended for best results. For 2012–2018 Jeep Wrangler models, exhaust modification is necessary, including the use of the Fabtech loop delete pipe (FTS94060). Additionally, 4-door models from 2007–2011 and 2012–2018 require specific front and rear driveshafts (FTS94057 front and FTS94052 or FTS94059 rear, respectively) to accommodate the suspension geometry changes.

The system supports a variety of tire and wheel combinations, with minor trimming or cutting required for larger tires and certain wheel offsets. Proper fitment ensures optimal performance and clearance without compromising vehicle safety.
