SBC Dished Piston Set 4.030 Bore -19cc

The SBC Dished Piston Set 4.030 Bore -19cc is a complete eight-piston set designed for small-block Chevy (SBC) engine builds that require precision-machined components for high-compression or forced-induction applications. This set is ideal for builders and performance enthusiasts who demand exact bore sizing and compression ratio control.

Constructed from hypereutectic aluminum alloy, the SBC Dished Piston Set offers superior heat dissipation and reduced thermal expansion compared to conventional cast pistons. The -19 cubic centimeter dish geometry reduces combustion chamber volume, optimizing fuel efficiency and power output across the RPM band. The precisely engineered ring groove dimensions (1/16 x 1/16 x 3/16 in) ensure proper ring fit and sealing integrity.

Engine builders constructing stroker motors, LS swap conversions with SBC block cores, or street/strip combinations will benefit most from this piston set. The dished top geometry not only lowers compression chamber volume but also helps manage detonation, making it critical for turbocharged or supercharged builds running premium fuel.
