4032 Aluminum Forged Pistons (Examples; SRP Pistons, Some Mahle Pistons )

• 4032 wrought aluminum alloy are designed for street/strip applications utilizing compression ratios that are compatible with pump gas. These pistons also provide a quieter engine on cold start up.

2618 Aluminum Forged Pistons (Examples; Diamond Pisons, Ross Pistons, Probe Pistons)

• 2618 wrought aluminum alloy are designed for higher performance applications utilizing high compression ratios and power adders such as NOS, Turbos, Supercharges, etc. These environments necessitate the higher tensile strength 2618 aluminum alloy.
