K4069DL

Overview:

The Fabtech 5-inch Trail LT Suspension System with DLSS Reservoir is engineered for Jeep Wrangler enthusiasts seeking a balance between aggressive off-road capability and refined on-road comfort. Designed to replace the factory lower link arms, this system enhances durability and articulation for tackling challenging terrain such as rock crawling, rugged trails, and extended overland expeditions. By utilizing the factory link arm mounts, the Trail LT system ensures a seamless integration with your Jeep’s existing chassis while delivering improved suspension travel and ride quality.

Ideal for Jeep Wrangler models from 2007 through 2018, including both two-door and Unlimited variants, this suspension kit offers a comprehensive upgrade that maintains factory load-carrying capacity and provides a smooth, quiet ride on highways. The inclusion of Fabtech’s Dirt Logic 2.25 DLSS reservoir shocks further refines damping performance, ensuring consistent control over diverse driving conditions.

Key Features:

This Trail LT suspension system combines advanced engineering and durable components to meet the demands of serious off-road enthusiasts:

• Replaces four vulnerable lower link arms with heavy-duty short arm links for enhanced off-road durability
• Large polyurethane bushings on one end and internal threads on the other to accept Fabtech’s 5 Ton Joint, providing longevity and reduced noise
• Dual-rate long travel coil springs maintain factory load capacity while offering extended suspension travel for aggressive rock crawling
• Adjustable front track bar and reinforced rear track bar bracket with support for improved axle alignment and stability
• Includes front and rear sway bar links to maintain proper sway bar function and vehicle control
• Front and rear brake lines and emergency brake bracket included for safe and reliable braking system integration
• Front bump stop extensions and rear bump stop brackets to protect suspension components during extreme articulation
• Equipped with Dirt Logic 2.25 reservoir shocks featuring remote reservoirs for superior heat dissipation and consistent damping

Construction & Design:

Fabtech’s Trail LT suspension system is built with rugged, high-strength materials engineered to withstand the harshest off-road environments. The short arm links are constructed with robust steel and feature large polyurethane bushings that reduce noise and vibration while enhancing durability. The internal threads accept Fabtech’s innovative 5 Ton Joint, a heavy-duty ball joint designed to extend service life and maintain smooth articulation under load.

The dual-rate coil springs are designed with a flexible coil pattern that balances factory load capacity with extended travel, allowing for aggressive off-road maneuvers without sacrificing on-road comfort. The Dirt Logic shocks incorporate remote reservoirs that improve fluid cooling and shock performance during prolonged off-road use, ensuring consistent ride quality and control.

Installation & Fitment:

Installation of the Fabtech Trail LT system requires welding and is recommended for experienced installers or professional shops. The kit is specifically designed for Jeep Wrangler models from 2007 to 2018, including the Wrangler JK series. Note that two-door models from 2007 to 2011 and 2012 to 2018 require specific driveshaft replacements (front FTS94057 and rear FTS94051 or FTS94058 respectively) to accommodate the suspension upgrade.

Proper wheel and tire fitment is critical: recommended tire sizes include 37x12.50R17, 37x12.50R18, and 37x12.50R20 with corresponding wheel sizes and backspacing as specified. Some configurations may require fender trimming or cutting, especially when using larger tires or tube fenders.
