It’s intended for performance and racing domestic engines that need application‑specific piston geometry. Made in the USA from 2618 aluminum, these pistons incorporate JE’s Forged Side Relief (FSR) forging to reduce skirt width and friction. Depending on application, an accumulator groove and skirt coating may be included to improve ring seal and reduce wear.
