SBC FT Powerpak Piston Set 4.125 Bore -5cc

The SBC FT Powerpak Piston Set 4.125 Bore -5cc by MAHLE PISTONS is designed for small-block Chevrolet enthusiasts who are building high-performance street and race engines. This piston set is essential for modern SBC builds, optimizing compression ratios while ensuring reliability across various boost levels and fuel grades. Whether you're working on a naturally aspirated stroker or a turbocharged application, these forged pistons provide the strength and precision needed for quality engine builds.

MAHLE's FT Powerpak line features a full-floating design and advanced forging technology, making them capable of handling sustained high RPM operation and cylinder pressure spikes. The 4.125-inch bore specification is compatible with late-model overbore blocks and Dart/World blocks commonly used in performance builds. The -5cc dish volume actively lowers the compression ratio, which is crucial when upgrading to forced induction or using lower-octane fuel without compromising durability.

Engine builders tackling turbocharged, supercharged, or nitrous-assisted small-block projects will find these pistons indispensable for maintaining compression control. Serious street rodders and bracket racers who demand verified performance under sustained load will appreciate the quality and reliability of the SBC FT Powerpak Piston Set.
