Fabtech Trail II Suspension Kit

2007–2018 Jeep Wrangler JK / Jeep Wrangler Unlimited

K4052M

Overview:

The Fabtech 3-inch Trail II Suspension Kit is engineered specifically for Jeep Wrangler JK models from 2007 through 2018, including both 2-door and 4-door Unlimited variants. Designed for serious off-road enthusiasts, this kit enhances your Jeep’s capability on aggressive trails, rock crawling, and overland expeditions while maintaining a smooth and quiet ride on the highway. By replacing the factory lower link arms with heavy-duty short arms, the Trail II system improves durability and articulation, addressing the vulnerabilities commonly encountered during off-road use.

This suspension kit is ideal for Jeep owners looking to run larger tires up to 37 inches with minor trimming or cutting, depending on wheel and tire combinations. It retains factory load-carrying capacities and provides balanced performance for both daily driving and demanding off-road adventures.

Key Features:

The Fabtech Trail II Suspension Kit incorporates advanced design elements to deliver superior off-road performance and on-road comfort:

• Replaces all four lower link arms with heavy-duty short arms for enhanced strength and obstacle clearance
• Large polyurethane bushings on one end and internally threaded ends to accept Fabtech’s 5 Ton Joint for durability and quiet operation
• Standard single-rate coil springs designed to maintain factory load capacities and provide balanced suspension performance
• Includes front and rear adjustable track bars for precise alignment and improved handling
• Equipped with Fabtech Stealth shocks for superior damping and ride quality
• Front and rear sway bar links included to maintain suspension geometry and control
• Brake line extensions and emergency brake bracket ensure proper fitment and safety
• Front bump stop extensions and rear bump stop brackets to prevent suspension over-compression
• Track bar bracket with rear support for added strength and stability

Construction & Design:

Fabtech’s Trail II Suspension Kit is built with high-quality materials engineered to withstand the rigors of off-road use. The short arm links are constructed with durable steel and feature large polyurethane bushings that resist wear and reduce noise. The internally threaded ends accommodate Fabtech’s patented 5 Ton Joints, which provide exceptional strength and longevity compared to standard ball joints.

The coil springs are designed as a single-rate setup, optimized to retain the Jeep’s factory load-carrying capacity while improving ride quality and articulation. The included Stealth shocks are tuned specifically for this suspension system, delivering consistent damping performance across varied terrain.

Installation & Fitment:

This suspension kit is designed for direct bolt-on installation utilizing the factory link arm mounts, simplifying the upgrade process. Minor trimming or cutting of fender components may be required depending on tire and wheel size combinations, especially when running 37-inch tires. Exhaust spacers are required for Jeep Wrangler models from 2012 onward to ensure proper clearance.

For off-road use, replacement driveshafts are recommended for 4-door models from 2007 to 2018 to accommodate the increased suspension travel and maintain drivetrain reliability.
