CP Piston BRS SBC 4.040 Bore 3.500 Stroke 5.700 Rod Set Of 8 (MTO Non-Cancel)

What you get in this set are eight forged pistons from CP Pistons, designed for a 4.040 inch bore with a 3.500 inch stroke and a 5.700 inch rod length. These are built for serious engine builds where strength and reliability are paramount. Forged pistons are a step up from cast or hypereutectic pistons because they start as a single block of aluminum that's heated and hammered into shape under extreme pressure. This process aligns the grain structure of the metal, making them significantly stronger and more resistant to detonation and high cylinder pressures.

CP Pistons is a well-known name in high-performance engine components, and this set reflects that reputation. The 4.040 inch bore size is common for many Small Block Chevy (SBC) engine builds, and the 3.500 inch stroke combined with the 5.700 inch rod length dictates the overall displacement and geometry of your rotating assembly. These pistons are built to handle the demands of performance applications, whether you're building a street/strip machine or a dedicated race engine. Because these are made-to-order, they are built to your specifications and are not cancellable once ordered.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're planning a high-performance engine build, especially one that will see significant stress, forged pistons like these are a solid choice for ensuring durability and performance. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning.
