CP Piston BRS BBC 4.320 Bore 4.250 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS BBC pistons, specifically sized for a 4.320 inch bore with a 4.250 inch stroke and a 6.385 inch rod length. These pistons are built for high-performance Big Block Chevrolet (BBC) engine builds where strength and reliability under extreme conditions are paramount. CP Pistons is well-known for their forged racing pistons, and this set is no exception, designed to handle the demands of serious engine work.

The BRS series pistons are forged from a strong aluminum alloy, which offers a good balance of durability and weight savings. This forging process creates a denser, more robust piston structure compared to cast pistons, making them resistant to deformation and failure under high cylinder pressures and temperatures. The specific dimensions – 4.320" bore, 4.250" stroke, and 6.385" rod length – indicate these are intended for a specific engine configuration, likely a stroker or performance-oriented build where these measurements are critical for proper engine geometry and performance tuning. They are made to order, meaning they are manufactured specifically for your purchase, ensuring you receive a fresh, high-quality component.

Because these pistons are made to order, they are non-cancelable and non-returnable once the order is placed. Please verify your engine specifications carefully before ordering. It's also important to note that this product is not CARB approved and cannot be shipped to California. For any engine build requiring robust, high-performance pistons for a Big Block Chevrolet, this set from CP Pistons offers a well-built solution designed for demanding applications.
