SBC Dished Piston Set 4.155 Bore -24.8cc

The SBC Dished Piston Set 4.155 Bore -24.8cc from RACE TEC PISTONS is designed for serious small-block Chevrolet builders focusing on high-compression, nitrous, or turbocharged applications. These dished pistons are engineered to reduce combustion chamber volume, enabling elevated compression ratios without the need for costly block modifications or cylinder head work.

The -24.8cc dish geometry creates a shallow dome that lowers peak piston height while ensuring structural integrity and ring support. This design is essential for nitrous and boosted applications, where managing peak cylinder pressure and preventing detonation is crucial. RACE TEC PISTONS manufactures these components to tight tolerances, ensuring a uniform bore fit across all eight cylinders.

This piston set is ideal for engine builders looking to achieve compression ratios ranging from 10.5:1 to 12:1, depending on rod length and deck height. It is particularly beneficial for those constructing street performance engines or weekend bracket racers. The 4.155-inch bore specification fits modern SBC blocks with standard overbore clearances, making it a versatile choice for various performance applications.
