Engineered to match the demands of the 5150 AutoSport B58 Stroker Kit, this custom-forged piston delivers extreme performance and uncompromising reliability for high-horsepower, long-stroke B58 builds. Developed in collaboration with CP-Carrillo, this stroker-specific piston is based on our Pro-Xtreme B58 design, with geometry tailored for the increased stroke and rod length in our 3.2L and 3.4L stroker kits.

Designed exclusively for use with the 5150 AutoSport Stroker Kit for BMW / Toyota B58 engines, this piston is what makes our record-breaking stroker builds possible.
