The JE Pistons forged eight‑cylinder piston kit for LS7 engines includes a -30cc dish profile with a 4.130 in bore and 1.115 CD for builds requiring lower chamber volume. JE’s FSR forging design reduces skirt width and friction while 2618 aluminum forgings supply high tensile strength; accumulator grooves and skirt coatings (when specified) help reduce ring flutter and wear for consistent operation.
