CP Piston BRS BBC 24.9CC Dome 4.500 Bore 4.375 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

If you're building a serious big block Chevrolet engine, you need pistons that can handle the stress and deliver reliable power. This set of CP Pistons BRS BBC pistons is built for those demanding applications. They feature a 24.9cc dome volume, which works with specific compression ratios depending on your cylinder head chamber size and head gasket thickness. The 4.500-inch bore size is standard for many popular big block configurations, and they're designed to work with a 4.375-inch stroke crankshaft and a 6.385-inch connecting rod. This combination is key for achieving the desired displacement and performance characteristics.

These pistons are forged from high-strength aluminum, a common practice for performance engine components because it offers a great balance of durability and weight savings. Forging creates a denser, more uniform grain structure in the metal compared to casting, making them much more resistant to the extreme pressures and temperatures found in a high-performance engine. The BRS series from CP Pistons is known for its robust construction, designed to withstand the rigors of racing and extreme street use. They are made-to-order, meaning they are built specifically for your order, ensuring precise manufacturing tolerances. This also means they are non-cancelable once ordered, so be sure this is the exact piston you need for your build.

This set includes eight pistons, enough for a complete V8 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. When planning your build, consider the specific requirements for your engine combination, including piston ring sets and wrist pins, which are typically sold separately. Consulting with your engine builder or a performance specialist is always a good idea to ensure these pistons are the right fit for your horsepower goals and engine combination.
