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 use modern steel wrist pins and real snap rings. They’re a great upgrade when rebuilding your 1939-1953 flathead Ford or Mercury V8 engine.

Original 4-ring design
Pressure cast aluminum construction provides great strength and durability
Precision cam ground
Modern steel wrist pins
Snap ring style retainer clips

The original bore size was 3.188", which makes these .060" oversize. Sold in sets of eight.
