K4051M

Overview:

The Fabtech 3-inch Trail II Suspension Kit is engineered specifically for Jeep Wrangler models from 2007 through 2018, including both the JK and JK Unlimited variants. Designed for serious off-road enthusiasts, this suspension system enhances your vehicle’s capability on rugged trails 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 kit addresses the common vulnerabilities encountered during aggressive off-road use such as rock crawling, trail riding, and overland expeditions.

This kit is ideal for Jeep owners seeking a reliable suspension upgrade that balances durability, ride comfort, and improved articulation. Fabtech’s Trail II system retains factory load-carrying capacities and incorporates advanced components to ensure long-lasting performance in demanding environments.

Key Features:

The Fabtech Trail II Suspension Kit offers a comprehensive set of features designed to optimize off-road performance and on-road comfort:

• Replaces all four lower link arms with heavy-duty short arms for enhanced durability and obstacle clearance
• Large polyurethane bushings on one end and Fabtech’s patented 5 Ton Joint on the other for quiet operation and extended service life
• Standard single-rate coil springs engineered to maintain factory load capacities and provide balanced suspension performance
• Includes front and rear adjustable track bars for precise alignment and improved handling
• Stealth shocks designed to deliver smooth damping and superior control over varied terrain
• Front and rear sway bar links to maintain suspension geometry and stability
• Brake line extensions front and rear to accommodate increased suspension travel
• Emergency brake bracket and bump stop extensions for enhanced safety and suspension protection
• Rear track bar bracket with support for added strength and durability

Construction & Design:

Fabtech’s Trail II Suspension Kit is built with high-quality materials and precision engineering to withstand the rigors of off-road use. The short arm links are constructed from heavy-duty steel with large polyurethane bushings that reduce noise and vibration while providing excellent articulation. The innovative 5 Ton Joint features internal threads and a robust design that significantly extends joint life compared to standard ball joints.

The coil springs are designed as a single-rate setup, offering a consistent spring rate that preserves the Jeep’s factory load capacity and ride characteristics. Stealth shocks included in the kit are tuned to provide a balance between off-road responsiveness and on-road comfort, ensuring a controlled and composed driving experience.

Installation & Fitment:

This suspension kit is engineered for direct fitment on 2007–2017 Jeep Wrangler models and 2018 Wrangler JK models, including Rubicon, Sahara, Sport, Sport S, and X trims. Installation requires replacing the factory lower link arms and associated components. Minor trimming or cutting may be necessary depending on tire and wheel size, especially when running larger tires such as 35” or 37” with specific wheel offsets.

For 2012 and newer Jeep Wranglers, exhaust spacers are required to complete the installation. Additionally, off-road use on 2-door models from 2007 to 2018 requires upgraded driveshafts (front and rear) to accommodate the increased suspension travel and articulation.
