The JE Pistons forged eight‑cylinder dome piston kit for LS7 engines features a 4.1275 in bore, 1.163 CD and a 3.10 cc dome profile for tuned compression. Built for racing and demanding domestic use, JE’s FSR forging minimizes skirt width and friction while 2618 aluminum provides high tensile strength; accumulator grooves and skirt coatings (when specified) improve ring seal and reduce wear.
