CP Piston BRS SBC 4.135 Bore 4.00 Stroke 6.00 Set Of 8 (MTO Non-Cancel)

CP Pistons is well-known for making strong, reliable internal engine components for high-performance applications. This set of BRS series pistons is a prime example, built for SBC (Small Block Chevy) engines with a 4.135-inch bore and a 4.00-inch stroke. These pistons are designed to handle the demands of serious engine builds, offering a solid foundation for increased power and durability.

Each piston in this set is forged, meaning the material is shaped under extreme pressure, resulting in a denser, stronger grain structure compared to cast pistons. This makes them much more resistant to the stresses of high compression, boost, or nitrous oxide. The BRS series features a specific design aimed at optimizing combustion and heat management within the cylinder. This set includes 8 pistons, and each one is 0.010 inches undersize, which is important to note for your engine machining and assembly process. Because these are made to order, they are not cancelable once production begins, so double-check your specifications before ordering.

When building a performance engine, the pistons are a critical component that directly impacts power output and longevity. This set from CP Pistons offers a well-built solution for enthusiasts looking to maximize their SBC engine's potential. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or machinist to ensure these specifications meet the requirements of your specific build.
