Description

The JE Pistons 258260S is a set of forged pistons designed for Chevy Big Block engines. These pistons feature a dome style with a 4.375-inch bore size, 4.000-inch crankshaft stroke, and a 6.385-inch rod length.

Constructed from 2618 forged aluminum, these pistons are built for high tensile strength and durability. They are precision CNC machined with ring grooves that accept 1/16, 1/16, 3/16 rings and accommodate oversized valves and long duration cams. The compression height is calculated using a 10.180-inch block height with zero deck clearance.
