JE Pistons forged eight‑cylinder piston kit for SBC applications, specified with a 4.030 in. bore, 1.125 compression height and -5.0 cc volume. The set is intended for demanding domestic and racing engines where tailored piston shape supports consistent combustion. Forged in the USA from 2618 aluminum, JE applies its Forged Side Relief (FSR) forging to minimize skirt width and friction. Depending on the application these pistons may include an accumulator groove and skirt coating to aid ring seal and reduce wear.
