About this part

Product Details

CP Pistons is well-known for making strong, reliable internal engine components for demanding builds. This Bullet Race Series piston set is a prime example, designed for Chevy LS engines that need to handle serious power. These aren't your everyday pistons; they're built for performance applications where durability and consistent operation are key.

This set features a 4.125 inch bore, a 3.622 inch stroke, and is designed to work with a 6.125 inch connecting rod. The wrist pin diameter is 1.300 inches. These pistons are forged, which means they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast or hypereutectic ones, making them ideal for high-compression, high-RPM, or forced-induction setups. The Bullet Race Series is engineered to withstand the rigors of racing and extreme performance driving.

This is a complete set of 8 pistons, ready to be installed in your Chevy LS engine. Because these are performance-oriented components, it's important to ensure they are compatible with your specific engine build and supporting components. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
