CP Piston BRS Big Bock Chevy 557 4.500 Bore 1.220 +46.9CC Set Of 8 (MTO Non-Cancel)

These CP Pistons BRS Big Block Chevy pistons are forged from a high-strength aluminum alloy, specifically chosen for its durability under extreme cylinder pressures. With a 4.500 inch bore and a 1.220 inch compression height, they are designed to work with a 4.250 inch stroke crankshaft, creating a 557 cubic inch displacement when installed in a standard 4.500 inch bore block. The dish volume is +46.9cc, which will influence your final compression ratio depending on your cylinder head volume.

CP Pistons is known for their precision manufacturing, and this set is no exception. Each piston is CNC-machined to tight tolerances, ensuring consistent performance and reliability for your high-performance Big Block Chevy build. The BRS series features a specific skirt design and ring land configuration aimed at improving oil control and reducing friction, which can lead to improved power and longevity. This set includes eight pistons, enough for a complete V8 engine rebuild. Because these are made to order, they cannot be canceled once the order is placed.

Please be aware that these pistons are not CARB approved and cannot be shipped to California. It is always recommended to consult with your engine builder to confirm compatibility with your specific cylinder heads, camshaft, and other engine components to achieve your desired compression ratio and performance goals.
