CP Piston BRS Big Block 4.500 Bore 4.375 Stroke 6.535 Rod 1.070 Set Of 8 (MTO Non-Cancel)

This is a set of CP Pistons BRS Big Block pistons, designed for a 4.500 inch bore with a 4.375 inch stroke. These pistons are built to work with a 6.535 inch connecting rod and feature a 1.070 inch compression height. This set includes eight pistons, ready for your high-performance big block engine build. CP Pistons is a well-known name in racing circles for producing robust engine components that can handle serious power.

The BRS series pistons are forged from high-strength aluminum alloy, a common practice for performance pistons because it offers a good balance of strength and weight. This forging process creates a denser, more uniform grain structure than casting, making them resistant to the extreme pressures and temperatures found in high-performance engines. The specific design of these pistons, including their dish volume and valve reliefs, is critical for achieving the desired compression ratio and ensuring proper valve-to-piston clearance with your chosen camshaft and cylinder heads. The 1.070 inch compression height is a key measurement that dictates how the piston sits in the cylinder bore relative to the crankshaft centerline, impacting your engine's overall deck height and compression.

Because these pistons are made-to-order (MTO), they are non-cancelable once the order is placed. Please double-check your specifications before ordering. This piston set is not CARB approved and cannot be shipped to California. Ensure you verify all engine specifications and clearances before installation to achieve optimal performance and reliability.
