Stock style pistons in modular engines are hypereutectic style. These Manley forged pistons will stand
up to much higher horsepower levels and are a necessity for supercharged, turbo charged and nitrous applications. They are designed to be compatible with 6.8L, 5.4L & 4.6L SOHC & DOHC modular engines utilizing stock stroke, rod length and .866 pins. These pistons must be used with Manley
ring sets. Manley currently produces pistons for some of the most well known aftermarket piston manufacturers. If these manufacturers rely on Manley you should too.
