CP Piston BRS BBC 4.530 Bore 4.000 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Big Block Chevrolet (BBC) engine and need pistons that can handle serious power, this set from CP Pistons is a solid choice. These are forged pistons, meaning 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, which is essential when you're pushing an engine hard, whether for racing, heavy towing, or just serious street performance. This particular set is designed for a 4.530-inch bore with a 4.000-inch stroke and uses a 6.385-inch connecting rod, a common configuration for many BBC builds.

CP Pistons is well-known in the performance engine world for making well-built components. These pistons are made to order, which means they are manufactured specifically for your purchase. This also means they are non-cancelable once the order is placed, so be sure this is the exact configuration you need for your build. The BRS designation typically refers to a specific skirt design and material treatment that CP Pistons uses to improve performance and durability under extreme conditions. While the exact material composition and specific skirt features are proprietary, the result is a piston designed to withstand high cylinder pressures and temperatures without failing.

This set includes eight pistons, enough for a standard V8 engine. Because these are made-to-order, please allow for manufacturing time. It's always a good idea to double-check your engine's bore, stroke, and connecting rod length requirements before ordering to ensure this set is the perfect fit for your project. Remember, these pistons are not CARB approved and cannot be shipped to California.
