KBP3127 Honda GX120 GX160 GX HX2 Quarter Midget Engine Gear shaft hub Shaft 3/4" - cnc machined from 1018 steel, 481 grams. Also Fits all briggs QM Engine gear boxes.

This is the gear hub used to hold the engine gear sprocket to the gearbox shaft - the hub is for the common triangle gears. This hub is made of 1018 Steel that has been zinc plated so it will not rust, the hub adds 481 grams to the rotating mass of the engine. When you flywheel is 1550 grams on the 120 or 2400 grams on the 160 this is a huge gain. While the weight is close to the shaft and would be better further from the shaft the difference is still a big gain. 

Most places make the light alum hub that is the opposite of what you want. This is momentum racing - the kids hold the gas to the floor and the car with the most momentum can case down anyone to win the race.
