Product Details
This is a set of eight CP Pistons BRS pistons, designed for Small Block Ford engines. You get the pistons themselves, ready for installation. These are built for a 4.155 inch bore, a 3.250 inch stroke, and are intended to be used with a 5.400 inch connecting rod. This specific set is made to order and cannot be canceled once placed, so be sure this is exactly what your build needs.
CP Pistons is known for making strong internal engine components, and this set is no exception. They are forged, which means the aluminum is shaped under extreme pressure, creating a denser and more robust piston than cast alternatives. This makes them well-suited for high-performance applications where durability and reliability under stress are critical. The BRS series is designed with specific features for improved performance and longevity in demanding builds. The 0.030 inch undersize means these pistons are machined to be 0.030 inches smaller than the standard bore size, which is important for engine rebuilding where cylinders might have been bored out to this specific dimension.
When building or rebuilding a performance engine, the pistons are a critical component that directly impacts power, efficiency, and durability. These CP Pistons offer a well-built solution for enthusiasts looking to maximize the potential of their Small Block Ford. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for detailed installation procedures and compatibility with other engine components.
