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.
