Pro-Tru

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.
• Pistons require 1/16"; 1/16"; 3/16" piston rings
