Ross Ford Flathead Pistons V8 Mercury & Ford Flathead Stroker Pistons and Ring Kits

 

 

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.
