Forged from high-strength 2618-T61 aluminum, these CP Pistons Bullet Race Series pistons are built for the demands of high-performance Small Block Chevy engines. The 4.155-inch bore size is a common choice for stroker combinations, and when paired with the 4.000-inch stroke and 6.000-inch rod length, they create a robust foundation for serious power. This set includes eight pistons, designed to handle the stresses of racing and extreme street use.

CP Pistons uses advanced forging techniques and rigorous testing to ensure their race series pistons can withstand extreme cylinder pressures and temperatures. The 2618-T61 aluminum alloy offers a good balance of strength and weight, crucial for high-RPM operation. These pistons are designed for a 4.155-inch bore, and the specific rod length of 6.000 inches is critical for achieving the correct compression ratio and piston-to-wall clearance when used with a 4.000-inch stroke crankshaft. Proper installation and ring gap setting are essential for optimal performance and longevity in these high-performance applications.

This set is intended for builders who are assembling a performance engine and require durable, well-made internal components. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for proper installation and tuning.
