JE Pistons forged eight‑piston kit for 400 small‑block Chevy (SBC) engines. Flat‑top pistons with a 4.125 in. bore, 1.000" compression distance and -6.00 cc crown volume supply a lower chamber volume option for SBC builds. Forged from 2618 aluminum in the USA and machined to application specs, the design includes JE's FSR forging to reduce friction; accumulator grooves and skirt coatings are applied where appropriate to improve ring performance.
