Description

The JE Pistons 323657L is a single dome piston designed for domestic applications. It is forged in the USA from 2618 aluminum, providing high tensile strength for demanding performance use. This piston features a proprietary Forged Side Relief (FSR) design to minimize friction and power loss, with reduced skirt width and a shorter wrist pin for weight savings.

The piston has a bore diameter of 4.140 inches, a compression height of 1.335 inches, and a pin diameter of 0.927 inches. It also includes an accumulator groove to improve ring seal and a skirt coating to reduce friction and wear.
