About Speed Pro street series hypereutectic pistons:
Dominating the horsepower-per-dollar race.
If
you're looking for pistons with an unbeatable combination of
performance and value, Speed-Pro hypereutectic pistons are for you.
These pistons are manufactured from FM244 aluminum alloy, which contains
16 percent silicon for greater strength and wear resistance. They're
also molded in the latest permanent-mold technology to ensure the
precise fit and tight bore clearances that today's top engine builders
demand. They're ideal for use in high performance street, bracket
racing, and oval track racing, and will work perfectly with normal ring
end gaps.
