Fabtech Crawler Long Arm Coil Suspension System

2007–2018 Jeep Wrangler JK (2-Door)

K4057M

Overview:

The Fabtech Crawler 3-inch long arm coil suspension system is engineered specifically for the Jeep Wrangler JK 2-door models from 2007 to 2018. Designed for serious off-road enthusiasts, this system replaces all eight factory link arms with extended length units that provide superior articulation and smooth operation at extreme suspension angles. By mounting the link arms higher on the frame, Fabtech increases ground clearance without the need to bend the links, unlike many other long arm kits on the market. This results in enhanced off-road capability while maintaining factory load carrying capacities and ride quality.

Ideal for Jeep owners seeking a durable, high-performance suspension upgrade, the Crawler system balances rugged construction with refined suspension tuning. It is compatible with a wide range of tire and wheel sizes, supporting aggressive setups up to 37-inch tires with minor trimming or cutting depending on wheel offset and fender configuration.

Key Features:

Fabtech’s Crawler system incorporates advanced engineering and premium components to deliver reliable, long-lasting performance:

• Complete replacement of all eight link arms with extended length, high-clearance units
• Link arms constructed from 2" OD, .313 thick wall DOM steel for exceptional strength
• Internally threaded link arms 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 designed to retain factory load carrying capacity
• Includes Fabtech Stealth shocks for improved ride quality and control
• Compatible with tire sizes ranging from 35x12.50R17 up to 37x12.50R20 with minor trimming or cutting
• Adjustable front track bar and rear track bar bracket included for precise alignment
• Front and rear sway bar links, brake lines, e-brake bracket, and bump stop extensions included for a complete suspension upgrade

Construction & Design:

Fabtech’s Crawler long arm system is built with durability and off-road performance in mind. The lower link arms are fabricated from heavy-duty 2-inch outer diameter DOM steel tubing with a .313-inch thick wall, providing exceptional resistance to bending and impact. Fabtech backs this strength with a warranty against bending, underscoring their confidence in the materials and craftsmanship.

The link arms feature internal threading to accept Fabtech’s innovative 5 Ton Joint, a robust design that eliminates wear issues common in traditional joints. The system’s track bar brackets are constructed from 1/4-inch thick steel and are weld-on for maximum strength and reliability, ensuring the suspension maintains proper geometry under extreme conditions.

Standard travel coil springs are engineered to maintain factory load ratings, delivering a balanced ride that supports both daily driving and demanding off-road use. The included Stealth shocks provide refined damping characteristics, enhancing control and comfort across varied terrain.

Installation & Fitment:

Installation of the Fabtech Crawler system requires welding and moderate mechanical expertise. It is designed specifically for 2-door Jeep Wrangler JK models from 2007 through 2018. Due to the lift height and suspension geometry changes, exhaust modifications are necessary on 2012–2018 models, requiring the Fabtech FTS94060 loop delete pipe.

Additionally, new driveshafts are required for proper fitment: front (FTS94057) and rear (FTS94051 for 2007–2011 models, FTS94058 for 2012–2018 models). Minor trimming or cutting of fenders may be necessary depending on tire and wheel size, especially when running 37-inch tires. This system supports a variety of wheel offsets and sizes, with detailed fitment guidelines provided to ensure compatibility.
