JE Pistons forged piston set for Big Block Chevrolet V8 applications — a set of eight .555‑dome pistons suited to racing and heavy‑duty street use. Built in the USA from 2618 aluminum, the FSR forging cuts skirt width and friction while reducing weight; accumulator grooves and skirt coatings are used where appropriate to enhance ring control and reduce operating noise. Specified for a 4.375 in. bore with 43.0 cc volume.
