Wiseco’s Pro-Tru line creates the best value in forged pistons today. These American made pistons are forged and machined by skilled Ohio craftsmen with state-of-the-art forging presses and CNC machines. By using dedicated forgings specific to the final piston shape; Pro-Tru pistons are stronger and lighter than industry standards. Pro-Tru pistons also come in a variety of volumes that allow the engine builder to choose the exact compression ratio required for their engine. RINGS ARE NOT INCLUDED.
Dome and reverse dome shapes have smooth contoured surfaces for better combustion and optimal quench for detonation reduction.
Symmetrical valve pocket designs allow maximum flow around the valves during overlap and accommodate oversize valves and high lift cams.
Piston skirt coating benefits include longer piston life; increased horsepower; noise reduction; and much tighter dimensional tolerances.
Complex piston skirt profiles reduce power robbing friction and rock; which promotes stability in bore for optimum ring-seal.
Precision machined ring grooves provide excellent surface finish and flatness for maximum ring-seal and minimized blow-by and oil consumption.
