Details
Original flathead pistons used four rings, were somewhat round, had questionable wrist pins and locks and were made of cast iron. These pressure-cast aluminum pistons share the four-ring design, but are cam ground and have modern steel wrist pins with real snap rings. They’re a great upgrade when rebuilding your 1939-1953 flathead Ford or Mercury V8 engine.
Sizing based on original 3.188" bore. Fits .060" overbore size and 3.75" stroke crank. Sold as a set of 8.
- Original 4-ring design
- Pressure cast aluminum construction provides great strength and durability
