The Fabtech 3-inch Trail II Coilover Suspension System is engineered specifically for Jeep Wrangler Unlimited models from 2007 to 2017 and JK 4-door models from 2018. Designed to enhance off-road capability while maintaining a smooth and quiet ride on the highway, this suspension system is ideal for enthusiasts who demand durability and performance across diverse terrains.

This system balances rugged off-road readiness with everyday drivability, making it a versatile upgrade for Jeep owners seeking enhanced suspension articulation and durability.

Key Features:

Fabtech’s Trail II Coilover system offers a comprehensive package designed to improve suspension strength and vehicle control:

• Replaces all four lower link arms with heavy-duty short arm links featuring large polyurethane bushings for durability and noise reduction
• Incorporates Fabtech’s patented 5 Ton Joint with internal threads for extended service life and quiet operation

Construction & Design:

Fabtech’s Trail II Coilovers are crafted from high-strength steel and engineered to endure the rigors of off-road driving. The short arm links feature large polyurethane bushings that reduce noise and vibration while providing long-lasting durability. The innovative 5 Ton Joint design incorporates internal threads, which significantly extend the lifespan of the joints compared to traditional designs. Coil springs are precision-engineered to retain factory load ratings, ensuring the suspension system supports the vehicle’s weight and accessories without compromising ride quality.

The Dirt Logic 2.25 shocks are specifically tuned to absorb harsh impacts and maintain control over rough terrain, while also delivering a comfortable ride on paved roads. All components are powder-coated for corrosion resistance, ensuring longevity in harsh environments.

Installation & Fitment:

The Fabtech Trail II Coilover system is designed for direct bolt-on installation using the factory link arm mounts, simplifying the upgrade process. Minor trimming or cutting of fender liners may be required depending on tire and wheel size combinations. Exhaust spacers are necessary for all installations on 2012 and newer Jeep Wranglers to ensure proper clearance. For off-road use, upgraded driveshafts are recommended for 4-door models from 2007 to 2018 to accommodate increased suspension travel.
