CP Piston BRS Big Block 4.530 Bore 4.375 Stroke 6.535 Rod 1.070 Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS Big Block pistons, designed for performance engine builds. You get the pistons themselves, ready to be installed in your engine. These pistons are specifically sized for a 4.530 inch bore, a 4.375 inch stroke, and are intended to be used with a 6.535 inch rod length, with a 1.070 inch compression height. They are built with a BRS (Big Block Special) design, indicating they are tailored for the demands of large displacement V8 engines.

CP Pistons is known for making well-built internal engine components, and these forged pistons are no exception. Forging is a process where the piston material is heated and shaped under pressure, resulting in a much stronger and more durable part compared to cast pistons. This makes them ideal for high-performance applications where increased cylinder pressures and temperatures are common. The 4.530 inch bore size is a common specification for many big block engine builds, and the specific stroke and rod length compatibility means these are engineered to work together for a particular engine configuration. The 1.070 inch compression height is also a critical measurement that determines the piston's position relative to the deck of the cylinder block at top dead center, impacting your final compression ratio.

Because these are made-to-order (MTO) and non-cancelable, it's important to be sure of your engine specifications before ordering. Please note that this product is not CARB approved and cannot be shipped to California. If you're rebuilding or building a high-performance big block engine, these CP Pistons offer a solid foundation for your rotating assembly.
