This asymmetric torque converter design has been very popular the past 30 yrs, and has been used on many different brands of 5 - 9 HP small engines, go-karts, and mini bikes.

This torque converter is an asymmetrical inline small engine clutch that 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.

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.

Our torque converter fits a 3/4" shaft and comes with a 12 tooth sprocket for a 35 chain & 10 tooth sprocket of a #41 chain. It will work with small engines producing 5.5 HP - 9 HP.

Engine comparability: It is compatible on most small engines with horizontal shaft.

Looks nice, can't install it.
The hardware it comes with to bolt to the predator 212 engine is the wrong thread pitch. Maybe some engines have a 18 thread pitch. Should include both course and fine bolts.
