If you're building a high-performance Chevy engine and need pistons that can handle serious power, this set from CP Pistons is a solid choice. These are forged pistons designed for 401 cubic inch applications, featuring a 4.125-inch bore and a 1.125-inch compression height. The 8cc dome volume is specific to certain compression ratio targets, so make sure it aligns with your build goals.

CP Pistons are well-known in the racing and performance world for their robust construction. These BRS series pistons are forged from high-strength aluminum alloy, which gives them the durability needed to withstand the extreme pressures and temperatures found in a performance engine. The forged process creates a denser, stronger grain structure compared to cast pistons, making them resistant to deformation and failure under high load. The specific dome shape and volume are critical for achieving your desired compression ratio, so it's important to pair these with the right cylinder heads and gasket thickness for your build.

This set includes eight pistons, rings, and wrist pins, ready for installation. Keep in mind that these pistons are made to order and are non-cancelable once production begins. Also, please note that this part is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
