CP Piston BRS SBC 4.145 Bore 3.750 Stroke 6.000 Rod Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from 2618-T61 aluminum, a strong and lightweight material chosen for its ability to handle high cylinder pressures and temperatures without deforming. The 4.145-inch bore size is a common upgrade for Small Block Chevrolet (SBC) engines, allowing for increased displacement and improved airflow. Paired with a 3.750-inch stroke and a 6.000-inch rod length, this set is designed to work with a specific crankshaft and connecting rod combination to achieve a desired compression ratio and engine balance.

CP Pistons is known for its precision manufacturing, and this set is no exception. Each piston is meticulously machined to ensure consistent weight and dimensions, which is critical for engine balance and smooth operation at high RPMs. The BRS series features a specific skirt design and ring land configuration aimed at optimizing performance and durability in demanding applications. This set includes all eight pistons, ready for installation into your SBC engine build.

Because these pistons are made-to-order, they are non-cancelable and non-returnable once production begins. Please verify your engine specifications and desired build parameters carefully before ordering. This piston set is not CARB approved and cannot be shipped to California.
