CP Piston BRS BBC 4.310 Bore 4.000 Stroke 6.135 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS BBC pistons, designed for big block Chevrolet engines. You get the pistons themselves, ready to be installed in your engine build. These are specifically sized for a 4.310 inch bore, a 4.000 inch stroke, and are intended to be used with 6.135 inch connecting rods. Because these are made to order, they are a non-cancelable purchase, so be sure these are the exact specifications you need for your project.

CP Pistons is known for their well-built forged pistons, and this set is no exception. Forged pistons start as a solid block of aluminum that is heated and hammered into shape under extreme pressure. This process aligns the grain structure of the metal, making the resulting piston significantly stronger and more durable than a cast piston. This strength is crucial for high-performance applications where engines experience high cylinder pressures and temperatures. The BRS series is designed for racing and high-output street use, offering a solid foundation for a powerful engine build. The specific bore size of 4.310 inches and stroke of 4.000 inches are common for many BBC applications, but always double-check your block and crankshaft dimensions to ensure compatibility.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance or racing engine, these CP Pistons offer a robust and reliable component. Remember to consult your engine builder or a trusted mechanic to confirm all dimensions and compatibility with other engine components like rings, pins, and connecting rods before ordering.
