Ross Ford and Mercury Flathead pistons are faithful reproductions of Art Sparks' original forged flathead Ford piston design. We have forged Flathead pistons available for Ford and Mercury stock stroke crankshafts as well as stroker flat head crankshafts. These pistons are machined on special ROSS flat head forgings for maximum strength, durability and minimum weight. Ross Ford flathead and Mercury flathead pistons are balanced to plus or minus 2.5 grams throughout the complete set.
If needed you can buy replacement pistons one at a time as needed. The unique skirt design allows the pistons to work properly under intense heat and high side loads without scuffing or splitting cylinder walls. Most normally aspirated pistons are designed to operate at .004 piston skirt to cylinder wall clearance.
The flathead Ford and Mercury engines are making a big comeback and are very popular now in hot rods, street rods and nostalgia drag cars. Start your flathead V8 engine rebuild off right with a set of Ross flathead pistons and piston rings. See the chart below for the wide range of available bore sizes, strokes, and piston ring types. They are available for standard stroke crankshafts, as well as stroker flathead engines. The flathead stroker pistons are available in several sizes. Why spend as much, or more, for antiquated stock type cast replacement pistons, when you can enjoy the numerous advantages of a modern high quality Ross forged piston set in your engine?
