This Sport System is tailored for 4-door Jeep Wrangler Unlimited models, providing a reliable lift solution that maintains vehicle stability and driveline integrity while accommodating larger tires and increased ground clearance.

Key Features:

Fabtech’s Sport System incorporates advanced suspension technology and robust components to optimize your Jeep’s performance:

• Dual rate coil springs designed for long travel suspension and smooth highway driving
• Corner-specific springs for the JL chassis to maintain side-to-side vehicle balance
• Four bump stop extensions that utilize factory bump stops for compliant cushioning at full compression
• Extended front and rear sway bar links with urethane bushings to prevent sway bar bind and maintain factory operating angles
• Heavy-duty rear track bar bracket to re-center the axle and preserve 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 as needed
• Maintains stock down travel to prevent over-cycling of suspension and driveline components
• Designed for 4-door Jeep Wrangler Unlimited models only, including Rubicon, Sahara, Sport, Willys, and special editions

Construction & Design:

The Fabtech Sport System features premium American-made coil springs engineered with a dual rate design. This innovative spring technology provides a softer initial rate for comfort and extended travel, while the second stage supports vehicle payload and absorbs large impacts at higher speeds. The coil springs are precisely corner-specific to the Jeep JL platform, ensuring the vehicle remains level side to side during suspension articulation.

All components, including bump stop extensions and sway bar links, are designed to integrate seamlessly with factory parts, preserving the Jeep’s original geometry and driveline angles. Heavy-duty materials and urethane bushings enhance durability and reduce wear, ensuring long-lasting performance in demanding off-road conditions.

Installation & Fitment:

This Sport System is designed for straightforward installation on 2020–2023 Jeep Wrangler Unlimited 4-door models equipped with Diesel or 392 engines. Minor trimming or cutting of fenders may be required depending on tire and wheel size, especially when using high clearance fenders with larger 37-inch tires. The system retains factory bump stops and down travel, minimizing suspension over-extension and driveline stress.

Extended sway bar links reposition the sway bars within their factory operating planes, preventing bind at full suspension extension. The heavy-duty rear track bar bracket re-centers the axle to maintain proper alignment and handling characteristics after lift installation.

What's Included:

• Dual rate coil springs (corner-specific for Jeep JL)
• Four bump stop extensions
• Extended front and rear sway bar links with urethane bushings
• Heavy-duty rear track bar bracket
• Shock extensions

The Fabtech 3-inch Sport System is ideal for Jeep Wrangler Unlimited owners who demand a balanced suspension upgrade that enhances off-road capability without compromising daily driving comfort. It suits enthusiasts who run larger tires up to 37 inches and require increased suspension travel for rugged terrain, while maintaining factory-like handling and driveline reliability. Perfect for off-road adventurers, weekend trail riders, and those seeking a versatile lift system engineered for both performance and durability.
