These 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 durability 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.
