SBC Dished Piston Set 4.030 Bore -15cc

The SBC Dished Piston Set 4.030 Bore -15cc from WISECO-PRO TRU is designed for serious small-block Chevrolet builders who demand precision and reliability in high-performance applications. This piston set is ideal for racers, street engine builders, and automotive enthusiasts who require controlled combustion dynamics in modified or stroker configurations.

Constructed from premium forged aluminum, these pistons feature a dished design that lowers the compression ratio, making them suitable for forced induction, nitrous, or high-boost applications. The -15cc dish geometry enhances fuel atomization and burn characteristics while helping to manage peak cylinder pressures, which is crucial for running aggressive ignition timing or alternative fuel blends.

This piston set is compatible with small-block Chevy engine builds targeting boost pressures above 8 psi and naturally aspirated high-compression builds that require detonation protection. Proper installation requires attention to ring gap setup and piston pin clearance to ensure optimal performance across various engine configurations.
