About Speed Pro street series power forged pistons:
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.
