About This Product
This MCS piston kit provides a .070 inch oversize for 1937 to 1941 80-inch (1300cc) Flathead models. Sold as a set, these cast aluminum pistons are ideal for a stock-style Side Valve rebuild. The kit is comprehensive, including the pistons, wrist pins, retainers, and rings. When you're working with these older engines, precision is everything, so make sure to double-check all your measurements before final assembly. A careful break-in period is mandatory to ensure the longevity of the new top end. This kit is a dependable way to restore compression and performance to a classic Harley-Davidson powerplant. OEM 22224-30 and 946487.
