CP Piston BRS SBC 4.155 Bore 3.750 Stroke 5.700 Rod Set Of 8 (MTO Non-Cancel)

What you get in this set are eight CP Pistons BRS Series pistons, specifically designed for Small Block Chevy (SBC) engines. These are not your average off-the-shelf pistons; they are built for performance applications, featuring a 4.155-inch bore and designed to work with a 3.750-inch stroke crankshaft and a 5.700-inch connecting rod. This combination is key for achieving specific displacement and performance goals in a performance engine build.

CP Pistons is known for their well-built forged pistons, and this BRS series is no exception. Forging is a process that aligns the grain structure of the metal, making the piston significantly stronger and more resistant to the extreme pressures and temperatures found in high-performance engines. This strength is crucial for reliability when you're pushing your engine hard. The 0.030-inch undersize specification means these pistons are precisely machined to be 0.030 inches smaller than the standard bore size, which is common when rebuilding or modifying an engine to ensure a proper fit and clearance within the cylinder wall.

It's important to note that these pistons are made to order (MTO) and cannot be canceled once the order is placed, so be sure of your specifications before purchasing. Also, these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance SBC and need a strong, reliable piston set that's built to handle demanding conditions, this CP Pistons set is a solid option.
