About Speed Pro Hypereutectic Pistons:
If
you're looking for pistons with an unbeatable combination of
performance and value, then 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.
