CP Piston BRS Big Block Ford 4.390 Bore 4.140 Stroke 6.800 Rod Set Of 8 (MTO Non-Cancel)

This set includes eight CP Pistons BRS pistons, designed for Big Block Ford engines. These pistons are forged from high-strength aluminum and are built to handle the demands of high-performance applications. They come at a 4.390 inch bore size and are 0.030 inch oversize, meaning they are intended for an engine block that has been bored out by 0.030 inches to match. The 4.140 inch stroke and 6.800 inch rod length specifications are crucial for matching with your crankshaft and connecting rods to achieve the correct engine displacement and geometry.

CP Pistons is known for their well-built forged pistons, and this set is no exception. The BRS series utilizes advanced forging techniques to create a piston that is both lightweight and incredibly strong, which is essential for engines that see significant stress. The material choice and construction help to ensure durability and consistent performance under extreme conditions. Because these are made-to-order, they are not cancelable once production begins, so be sure of your specifications before ordering.

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 fit for your specific Big Block Ford build and that all other components, like your crankshaft, connecting rods, and cylinder heads, are compatible with the 0.030 inch oversize bore.
