JE Pistons forged eight‑piston kit for 400 small‑block Chevy (SBC) engines. Flat‑top pistons with a 4.165 in. bore, 1.000" compression distance and -6.00 cc crown volume suit high‑displacement SBC builds that need precise chamber sizing. Forged and machined in the USA from 2618 aluminum, the pistons use JE's FSR forging to reduce friction; accumulator grooves and optional skirt coatings aid ring control where specified.
