Description

The JE Pistons SRP Professional 321405 pistons are lightweight FSR forged pistons made from high-silicon 4032 aluminum alloy, featuring accumulator grooves for improved ring seal and skirt coating. They are designed for highly modified Ford Small Block Windsor engines with custom stroker builds, supporting normally aspirated or moderate forced induction/nitrous applications. These pistons have a 4.040-inch bore, 4.250-inch crankshaft stroke, 6.250-inch rod length, and an inverted dome of -12.5cc, making them suitable for custom high-performance engine configurations.
