5150 AutoSport B58 Stroker Forged Piston – Pro-Xtreme Series

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.

Rated for up to 2000 horsepower and 9500 RPM, this piston is made for high boost builds—whether you're drag racing, doing roll racing, or running a full race-prepped street car. It's forged from aerospace-grade aluminum and engineered using CAD and FEA technology to reduce weight, manage heat, and thrive under extreme cylinder pressures.

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.

Key Features:

  • Custom-forged for the 5150 AutoSport B58 Stroker Kit
  • Built on the Pro-Xtreme piston platform manufactured for 5150 by CP-Carrillo
  • Supports up to 2000 HP and 9500 RPM
  • Forged from high-strength, aircraft-grade aluminum alloy
  • CAD/FEA optimized for strength, weight savings, and thermal efficiency
  • Handles high compression and extreme boost
  • Ideal for B58 stroker builds, drag racing, and high-performance street cars
