Key Features:

Fabtech’s 3in Sport System combines innovative design with durable materials to deliver a reliable and versatile suspension upgrade. Key features include:

• American-made dual rate coil springs designed for long travel suspension and smooth highway ride
• Corner-specific springs tailored to the Jeep Wrangler JL chassis for balanced side-to-side leveling
• Two-stage spring design: soft initial compression for comfort and a firmer second stage for payload and impact absorption
• Four bump stop extensions that utilize factory bump stops to provide compliant cushioning at full compression
• Extended front and rear sway bar links with urethane bushings to prevent binding and maintain factory sway bar operation
• Heavy-duty rear track bar bracket to re-center the axle while preserving the factory roll center with increased ride height
• Compatible with standard and high clearance fenders, supporting tire sizes up to 37x12.5R20 with minor trimming or cutting
• Designed specifically for 4-door Jeep Wrangler Unlimited models, including 4XE variants

Construction & Design:

The Fabtech 3in Sport System is built with high-quality materials engineered for durability and performance. The coil springs are manufactured in the USA using a dual rate design that balances ride comfort with off-road capability. This design allows the springs to compress softly during normal driving conditions while providing additional support under heavy loads or rough terrain.

Extended sway bar links with urethane bushings ensure smooth articulation and prevent binding during full suspension travel. The heavy-duty rear track bar bracket is precision-engineered to maintain axle alignment and the vehicle’s roll center, preserving handling characteristics despite the increased ride height.

Installation & Fitment:

This system is designed for direct fitment on 2021 Jeep Wrangler Unlimited 4-door models, including the 4XE variants. Installation requires minor trimming or cutting of fenders depending on tire and wheel size combinations. Fabtech provides detailed instructions to facilitate a straightforward installation process, suitable for experienced DIYers or professional installers.

The system supports a variety of tire and wheel sizes, from 35-inch tires on 17- to 20-inch wheels with standard fenders to 37-inch tires with high clearance fenders. This flexibility allows you to tailor your build to your specific off-road and aesthetic preferences.
