Speed-Pro forged pistons are made from extruded VMS-75 aluminum alloy that's forged under 3,000 tons of pressure to "near-net" shape. After that, they're machined to their final configuration. These pistons offer excellent strength and durabilityâ€”and are capable of taking the punishment that's dished out on the street and in competition. They're available for a wide variety of applications, including OE replacements and all-out racing engines.
