This JE forged piston kit for the BMW S50B32 supplies six engine-specific pistons forged and machined in the USA. The proprietary Forged Side Relief (FSR) design reduces skirt width and weight to minimize friction, while accumulator grooves reduce combustion gas pressure on rings. Where specified, skirt coatings lower friction and noise. Forged from 2618 aluminum and supplied with quality wrist pins, locks and JE Pro Seal rings.
