SBF F/T Piston Set 4.040 Bore -6.5cc

The KB PERFORMANCE PISTONS SBF F/T Piston Set 4.040 Bore -6.5cc is designed for Small Block Ford enthusiasts who are building high-performance or full-throttle racing engines. This piston set is ideal for applications requiring aggressive compression ratios and optimized combustion chamber geometry, making it suitable for naturally aspirated stroker builds and competition-level power plants.

Manufactured from premium aluminum alloy, these forged pistons are precision-engineered to ensure consistent bore fit and minimal ring gap variation. The -6.5cc dish design effectively lowers static compression and provides a detonation margin for high-octane pump gas builds or boost applications. This attention to detail ensures reliability and performance under sustained high-RPM operation.

Engine builders, machine shops, and performance enthusiasts will find this piston set particularly beneficial for complete Small Block Ford rebuilds. It is specifically designed to meet the demands of those looking for more than OEM or budget-tier pistons can offer, ensuring both power and reliability in high-performance applications.
