CP Piston BRS SBC 4.155 Bore 3.500 Stroke 6.00 Rod 1.250 Set Of 8 (MTO Non-Cancel)

This is a set of CP Pistons Billet Racing Series (BRS) pistons designed for Small Block Chevy (SBC) engines. These are not your average pistons; they are built for high-performance applications where strength and reliability are critical. The BRS line uses a billet material, which is a solid block of aluminum that is machined to shape, offering a very strong and consistent structure compared to cast or forged pistons made from ingots. This set features a 4.155-inch bore and a 3.500-inch stroke, paired with a 6.00-inch connecting rod length, and uses a 1.250-inch wrist pin. This specific configuration is often chosen for builds aiming for significant displacement increases and robust power output.

CP Pistons is well-known in racing circles for their attention to detail and the durability of their components. The billet construction means these pistons can handle extreme cylinder pressures and temperatures that would typically cause failure in less robust designs. They are designed to be a direct replacement for your existing pistons, assuming your engine block has been machined to the specified bore size. The set includes eight pistons, enough for a full V8 engine. Because these are made-to-order, they are non-cancelable once production begins, so be sure this is the exact specification you need for your build.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance SBC engine and need pistons that can withstand serious abuse, this billet set from CP Pistons is a solid option. Always consult your engine builder and machine shop to ensure these specifications align with your overall engine plan and that your block is prepared accordingly.
