About this part

Product Details

These CP Pistons are built with a 4.155 inch bore and a 3.76 inch stroke, designed for BBC (Big Block Chevrolet) engines. They utilize a 6.135 inch rod length, which is a critical measurement for engine geometry and balancing. This set includes eight pistons, ready for a complete engine build. Because these are made-to-order, they are non-cancelable once production begins, so double-check your specifications before ordering.

The BRS series pistons are forged from high-strength aluminum alloy, a common choice for performance engines because it offers a good balance of strength and weight. This forging process creates a denser, more durable piston structure compared to cast aluminum, allowing them to withstand the higher pressures and temperatures found in performance applications. The specific design of these pistons is optimized for the demands of a BBC engine, ensuring they can handle significant power output. They are designed to fit with a 0.030 inch overbore, which is a common size for rebuilding or upgrading an engine block.

This set is a significant component for anyone rebuilding or significantly upgrading their BBC engine. Given the custom nature of these pistons, it's important to ensure they align with your camshaft, cylinder head, and crankshaft specifications for optimal performance and engine longevity. They are not CARB approved and cannot be shipped to California.
