CP Piston BRS Big Block 4.560 Bore 4.375 Stroke 6.385 Rod 1.220 Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP-Carrillo BRS pistons are built for serious big block performance. The 4.560-inch bore and 4.375-inch stroke are designed to work with a 6.385-inch connecting rod, creating a robust combination for high-output engines. The 1.220-inch compression height is a key measurement that dictates how the piston sits in the cylinder relative to the deck surface, influencing your final compression ratio and chamber volume.

CP-Carrillo is known for its precision manufacturing, and these pistons are no exception. The BRS series features a specific skirt design and forging process aimed at durability and optimal performance under demanding conditions. This set includes eight pistons, ready for your custom engine build. Because these are Made-To-Order (MTO) and non-cancelable, it's important to verify your specifications before ordering.

When building a high-performance engine, piston selection is critical. These pistons are designed for builders who understand the importance of precise measurements and robust materials. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications for complete compatibility and installation details.
