What's in the Box

Info

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.

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
  • Precision cam ground
  • Modern steel wrist pins
  • Snap ring style retainer clips

The proper skirt clearance is .0025" to .003" for these flathead pistons. These pistons are .060" oversized of the original 3.188" bore.
