CP Piston BRS Big Block 4.500 Bore 4.250 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

CP Pistons is well-known for making serious engine components for high-performance applications. This set of BRS pistons is built for big block engines, designed to handle the demands of powerful builds. They feature a 4.500-inch bore and are intended for a 4.250-inch stroke with a 6.385-inch rod length. This specific configuration is crucial for achieving the correct compression ratio and displacement in your engine build.

These pistons are forged, meaning they start as a solid block of aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast alternatives, making them ideal for engines that will see heavy use or high cylinder pressures. The BRS series is designed with specific features to improve performance and reliability under stress. Each piston in this set of eight is precisely machined to ensure consistent performance across all cylinders.

Because these pistons are made to order, they are non-cancelable once production begins. This ensures you receive a fresh set built to your specifications. Please note that this part is not CARB approved and cannot be shipped to California. If you're building a high-performance big block, these pistons offer a solid foundation for your engine.
