Lifeline SFI 17.1 Mechanical + Automatic Fire Suppression System

Drawing from decades of experience designing and supporting the industry-leading Sprint Car fire suppression system, Lifeline has created the SFI 17.1 Mechanical + Automatic Fire System—engineered for simplicity, light weight, and maximum performance. Whether you’re charging through the deserts of Baja or turning laps at Daytona, this race-proven system provides unmatched protection with both mechanical and automatic activation.

Dual Activation for Complete Protection

The system features mechanical activation via a 6-foot pull cable, paired with automatic thermal bulb activation for rapid, hands-free response to fire. This dual-activation design offers redundancy and speed, ensuring fire suppression begins even if the driver cannot manually trigger the system.

Industry-Leading Performance Features
