CP Piston BRS Big Block 4.600 Bore 4.375 Stroke 6.385 Rod 1.220 Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS Big Block pistons, designed for performance engine builds. These pistons feature a 4.600-inch bore, a 4.375-inch stroke, and are intended to be used with a 6.385-inch connecting rod. The wrist pin diameter is 1.220 inches. These are custom-made, non-cancelable parts, meaning once ordered, they cannot be returned or canceled.

CP Pistons is known for making well-built internal engine components for demanding applications. These pistons are forged, which means they start as a solid block of aluminum that is heated and then pressed into shape under extreme pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for high-performance engines where increased cylinder pressures and temperatures are common. The BRS series is engineered for specific applications, and these particular pistons are sized for a big block engine configuration. The specific bore size of 4.600 inches and stroke of 4.375 inches are critical dimensions that determine the engine's displacement and overall performance characteristics when paired with the correct crankshaft and connecting rods.

When building a high-performance big block engine, selecting the right pistons is crucial for reliability and power. These CP Pistons are a solid option for builders looking for custom-sized, forged components. It's important to 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 to ensure these pistons are the correct choice for your specific engine build and that all necessary supporting components, such as rings, wrist pins, and connecting rods, are compatible.
