CP Piston BRS SBC 4.125 Bore 3.750 Stroke 5.700 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS forged pistons designed for Small Block Chevy (SBC) engines. They feature a 4.125 inch bore, a 3.750 inch stroke, and are intended to be used with a 5.700 inch connecting rod. These pistons are built to order and are a critical component for anyone rebuilding or upgrading a high-performance SBC engine, especially those looking for specific bore and stroke combinations for custom builds.

CP Pistons is known for producing well-built internal engine components, and this piston set is no exception. The BRS series is engineered for strength and reliability under demanding conditions. The forged construction means these pistons start as a solid block of aluminum alloy that is heated and hammered into shape, creating a grain structure that is much stronger and more durable than cast pistons. This makes them ideal for applications where high compression, boost, or nitrous oxide will be used. The 4.125 inch bore size is a common upgrade for SBC engines, allowing for increased displacement and potential power gains when paired with the correct crankshaft and connecting rods.

This set is for standard bore size (STD) and is made to order, meaning it's built specifically for your purchase. Because they are custom-made, please note that these pistons are non-cancelable once ordered. They are not CARB approved and cannot be shipped to California. If you're building a performance engine where precision and strength are paramount, these CP Pistons offer a solid foundation.
