10T Heavy Duty Centrifugal Clutch 1" Bore, #420

Heavy duty centrifugal clutch 1"bore 10 tooth #41/420 chain. Rated up to 7hp.

This fits on a 1" crankshaft the other end is 3/8".  The end of the crankshaft must be drilled and tapped to accept a bolt to hold clutch onto shaft.  Comes with two set screws and 1/4" key.  This is a heavy duty clutch designed for standard live axle karts using up to 18" tall tires.  This will not take the place of a torque converter, but is ideal for fairly flat land riding. 

The 10t sprocket allows you to achieve a desired gear ratio for good pulling power, recommend using at least a 60T drive sprocket.  Others offer a 14T clutch that does not have near the pulling power needed. 
 
For larger tire application and extreme riding, you will need a torque converter.
