Key Features:

This comprehensive lift kit includes advanced components engineered to improve suspension dynamics and vehicle stance:

• 3-inch front and rear lift for increased ground clearance and tire clearance
• Dual-rate front coil springs providing a soft initial ride with extended travel and a firmer second stage for payload and impact absorption
• Rear coil spring spacers (1-3/4" height) to maintain factory load carrying capacity and level stance
• Four bump stop extensions that utilize factory bump stops for compliant cushioning and prevent over-cycling of suspension and driveline
• Extended front and rear sway bar links with durable urethane bushings to maintain proper sway bar geometry and prevent binding at full suspension travel
• Fabtech Stealth monotube shocks for enhanced damping performance on and off-road
• Compatible with a wide range of tire sizes up to 37-inch diameter depending on fender configuration
• Designed specifically for diesel-powered Jeep Gladiator models with standard or high clearance fenders

Construction & Design:

Fabtech’s Sport System is engineered with high-quality materials and precision manufacturing to ensure durability and long-lasting performance. The dual-rate coil springs are designed to optimize suspension travel and ride comfort, while the monotube Stealth shocks provide consistent damping under demanding conditions. Urethane bushings on sway bar links reduce deflection and wear, maintaining suspension geometry and handling characteristics. The coil spring spacers are crafted to retain factory load ratings, ensuring the vehicle’s payload capabilities remain uncompromised.

Every component is designed to integrate seamlessly with the Gladiator’s factory suspension, preserving driveline angles and minimizing the need for additional modifications. This thoughtful engineering results in a lift kit that enhances off-road capability without sacrificing on-road manners.
