BLAST LED torque converter is an asymmetrical inline small engine clutch that is nearly the same as a Comet TAV2 30 75 Torq A Verter. This clutch will help you get more power out of your small engine by reducing engine load. A torque converter acts similar to a transmission, allows higher speeds out of your small engine, and smoother acceleration. Small engine Torque Converter clutches are heavily used in riding lawnmowers, small tractors, go karts, mini bikes, mini choppers, ATV, motorcycles, and waterski winches. Engagement range is approximately 2350 RPM; however, this can be adjusted from Minimum 1200 RPM - Maximum 3100 RPM by changing out springs (not included) and other adjustments.
