CP Piston BRS BBC 4.500 Bore 4.000 Stroke 6.135 Rod Set Of 8 (MTO Non-Cancel)

If you're building a high-performance big block Chevrolet engine, a solid set of pistons is where it all starts. This set from CP Pistons is designed for a 4.500 inch bore with a 4.000 inch stroke, using a 6.135 inch rod. These are forged pistons, which means they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process aligns the grain structure of the metal, making them much stronger and more durable than cast pistons, especially under the extreme heat and pressure found in a performance engine.

CP Pistons is known for making well-built components for serious engine builds. These pistons are made to order, so you know they're being produced specifically for your application. This also means they are non-cancelable once the order is placed. The BRS series is a popular choice for builders looking for reliable performance. They are designed to handle the demands of racing and high-horsepower street applications. Remember, these pistons are not CARB approved and cannot be shipped to California.

This set includes eight pistons, enough for a complete 8-cylinder engine. When planning your build, ensure you have the correct supporting components, such as rings, pins, and locks, as these are typically sold separately. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to get the most out of these performance pistons.
