SBC Domed Piston Set 4.155 Bore +6.2cc

The JE PISTONS SBC Domed Piston Set 4.155 Bore +6.2cc is designed for small-block Chevy engine builders who demand high performance and reliability. These forged pistons are essential for high-output builds, particularly in naturally aspirated engines where maximizing compression is crucial. Whether you're building a street engine or a race motor, this piston set provides the quality needed for serious applications.

Manufactured from premium forged aluminum, these pistons offer superior strength and thermal stability, making them ideal for high-performance applications where cylinder pressures exceed stock levels. The 4.155-inch bore size is suitable for popular overbore applications, allowing builders to reclaim displacement after boring or to start from a fresh block. The dome volume of +6.2cc contributes to increasing the engine's compression ratio when paired with compatible cylinder head chamber volumes.

This piston set is perfect for small-block Chevy platforms, including 350, 383, 406, and other overbored variants commonly found in performance vehicles. Builders will appreciate the attention to detail in the design, which minimizes blowby and friction losses, ensuring consistent performance across the RPM range. Installation requires matching components to achieve optimal results.
