The JE Pistons forged eight‑cylinder piston kit for LS7 engines features a -30cc dish profile with a 4.125 in bore and 1.115 CD, suited to engine builds needing reduced chamber volume. JE’s FSR forging reduces skirt width and friction, and the 2618 aluminum construction supplies high tensile strength; accumulator grooves and skirt coatings (application dependent) help control ring flutter and reduce wear.
