Key Features:

Fabtech’s Trail Suspension System incorporates advanced engineering and premium materials to deliver superior off-road performance and ride quality:

• Complete short arm suspension design using factory control arm mounts for easy installation
• Heavy-duty link arms constructed from 1.75" OD, .250" thick wall steel tubing, guaranteed never to bend
• Large polyurethane bushings paired with Fabtech’s patented 5 Ton Joint for quiet operation and extended durability
• Long travel, dual rate coil springs that are corner-specific to the Jeep JL chassis for balanced ride height and increased suspension travel
• Dual-stage coil springs providing a soft initial ride with progressive support for payload and high-speed impact absorption
• Draglink Flip System and heavy-duty track bar bracket to correct steering geometry and prevent binding during full articulation
• Maintains factory draglink angle to pitman arm, reducing side load on the steering box and extending its service life
• Heavy-duty rear track bar bracket with side support to maintain factory roll center and axle alignment
• Front and rear bump stop extensions to protect suspension components from over-travel damage

Construction & Design:

Fabtech’s Trail Suspension System is built with rugged, high-strength materials designed to withstand the rigors of heavy off-road use. The link arms feature thick-walled steel tubing for exceptional strength and resistance to bending or deformation. Polyurethane bushings enhance durability and reduce noise, while the innovative 5 Ton Joint provides a maintenance-free, long-lasting pivot point that outperforms traditional ball joints.

The dual rate coil springs are engineered specifically for the Jeep JL platform, ensuring precise corner balancing and optimized suspension travel. The system’s design maintains factory mounting points and geometry, preserving vehicle handling characteristics while accommodating a 3-inch lift.

Installation & Fitment:

This suspension kit is designed for straightforward installation on 2018 to 2021 Jeep Wrangler 6-cylinder 4-door models, including Rubicon, Sport, Sport S, Unlimited Rubicon, Unlimited Sahara, Unlimited Sport, and Unlimited Sport S trims. The system uses factory control arm mounts, minimizing modifications and simplifying the upgrade process. Minor trimming or cutting may be required depending on tire and wheel size, especially when using high clearance fenders or larger tires up to 37 inches.

For heavy off-road use, upgraded driveshafts are recommended (front FTS94057 and rear FTS94065) to handle increased suspension articulation and drivetrain stress.
