JE Pistons forged eight‑piston kit for 400 small‑block Chevy (SBC) engines. Flat‑top pistons with a 4.165 in. bore, 1.062" compression distance and -6.00 cc crown volume are suited to stroked SBC builds requiring a specific chamber profile. Manufactured and machined in the USA from 2618 aluminum, the design uses JE's FSR forging to cut friction; accumulator grooves and optional skirt coatings enhance ring stability when specified.
