SBC Dished Piston Set 4.155 Bore -12cc

The SBC Dished Piston Set 4.155 Bore -12cc from KB Performance Pistons is engineered for small-block Chevrolet engines requiring precision-matched internal components. This piston set delivers the reliability demanded in high-performance and duty applications where engine integrity directly impacts mission success. Built to exacting tolerances, this product serves engine builders, mechanics, and enthusiasts who prioritize durability and consistent performance under demanding conditions.

The -12cc dished configuration reduces combustion chamber volume, optimizing compression ratios for enhanced fuel efficiency and power delivery in small-block Chevrolet platforms. KB Performance Pistons are manufactured using premium alloy materials selected for thermal stability and resistance to detonation—critical factors in engines operating at sustained high RPM or elevated boost levels. The 4.155-inch bore specification ensures precise fitment within OEM and aftermarket small-block Chevrolet blocks, while the dished design accommodates valve clearance and supports proper combustion geometry across a range of cylinder head configurations.

Engine builders and performance technicians rely on this piston set for street, strip, and crate engine applications where quality internals are non-negotiable. Installation requires proper ring end-gap setup, accurate bore sizing, and correct rod-to-piston matching to ensure longevity and prevent catastrophic failure. Verify compatibility with your specific cylinder head, intake manifold design, and intended compression ratio before ordering to confirm optimal valve clearance and performance characteristics.
