The JE Pistons forged eight‑cylinder dome piston kit for LS7 engines is sized for a 4.125 in bore, 1.163 CD and a 3.20 cc dome, offering a higher‑compression option for performance builds. JE’s Forged Side Relief (FSR) forging reduces skirt friction and weight, and the 2618 aluminum construction supplies strength; optional accumulator grooves and skirt coatings help control ring flutter and wear.
