CP Piston BRS Small Block 4.00 Bore 3.550 Stroke 6.00 Rod 1.225 Set Of 8 (MTO Non-Cancel)

CP Pistons is well-known for making high-performance internal engine components, and this BRS piston set is a prime example of their work for serious engine builds. This set is designed for small block engines and features a 4.00-inch bore with a 3.550-inch stroke, intended to be used with a 6.00-inch connecting rod. The 1.225-inch compression height is a key measurement that determines how the piston sits in the cylinder relative to the deck surface, impacting your compression ratio.

These pistons are forged, meaning they start as a solid block of aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for high-stress applications where reliability is paramount. The BRS designation often indicates specific design features aimed at improved performance and durability under demanding conditions. Because these are made to order, you're getting a fresh set built specifically for your application, ensuring the highest level of precision.

This is a set of 8 pistons, which is standard for most V8 engines. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to confirm all your engine dimensions and clearances before ordering custom internal components like these.
