Construction & Design:

Fabtech’s Sport System is engineered with high-quality materials and precision craftsmanship. The coil springs are made in the USA and feature a dual rate design that balances comfort and performance by providing a soft initial spring rate for daily driving and a firmer secondary rate to handle payload and high-speed impacts. The bump stop extensions are designed to work seamlessly with factory components, ensuring compliant cushioning at full suspension compression.

Extended sway bar links with durable urethane bushings maintain proper sway bar geometry and prevent binding during full suspension articulation. The heavy-duty rear track bar bracket is engineered to maintain the factory roll center, ensuring stable handling and axle alignment after lift installation. Stealth monotube shocks provide consistent damping performance across varied terrain and driving conditions.

Installation & Fitment:

The Fabtech Sport System is designed for straightforward installation on 2018 to 2021 Jeep Wrangler models equipped with 4- or 6-cylinder engines. Minor trimming or cutting of the fenders may be required depending on tire and wheel size, especially when using high clearance fenders with larger tires. The system retains factory bump stops and down travel to prevent over-cycling of the suspension and driveline components, preserving vehicle reliability.
