CP Piston BRS SBC 4.020 Bore 3.480 Stroke 5.700 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS Series pistons, specifically sized for a 4.020 inch bore with a 3.480 inch stroke and designed to work with a 5.700 inch connecting rod. These pistons are built for Small Block Chevy (SBC) engines and are made to order, meaning they are manufactured specifically for your purchase and cannot be canceled once ordered. This set is ideal for builders looking for a well-built, custom-spec piston for their performance engine build.

CP Pistons is known for their attention to detail and robust construction, and this BRS Series set is no exception. These pistons are forged, which means they start as a solid block of aluminum that is heated and then pressed into shape. This process creates a much stronger and more durable piston than cast alternatives, making them suitable for high-performance applications where increased cylinder pressures and temperatures are common. The specific bore size of 4.020 inches is a common upgrade for many SBC engine blocks, allowing for increased displacement and potential power gains when paired with the correct crankshaft and connecting rods. The 5.700 inch rod length is also a critical dimension that affects the piston's compression height and overall engine geometry, ensuring proper fitment and performance within the engine.

Because these pistons are made to order, please allow for manufacturing time. They are not CARB approved and cannot be shipped to California. This set is a significant component for anyone serious about building a high-performance SBC engine, offering a solid foundation for power and reliability.
