CP Piston BRS Big Block 4.080 Bore 3.980 Stroke 6.490 Rod Set Of 8 (MTO Non-Cancel)

If you're building a high-performance big block engine, getting the right pistons is crucial for reliability and power. This set from CP Pistons is designed for a 4.080 inch bore with a 3.980 inch stroke, and uses a 6.490 inch rod length. 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 creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see hard use or high horsepower applications.

CP Pistons is known for making well-built engine components, and this set is no exception. The BRS series is a popular choice for builders looking for a solid foundation for their performance engine. Because these are made to order, you know you're getting a fresh set built specifically for your order, and they are non-cancelable once production begins. This also means you should plan ahead for lead time, as they aren't kept in stock.

This set includes eight pistons, enough for a standard V8 big block engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details, especially when dealing with custom engine builds.
