Forged from high-strength aluminum alloy, these CP Pistons Bullet Race Series pistons are built for the demanding requirements of a Chevy LS7 engine. The 4.125-inch bore size is specifically chosen for the LS7's larger displacement, and when paired with the 4.000-inch stroke crankshaft and 6.125-inch connecting rods, they create a robust rotating assembly ready for serious performance.

The Bullet Race Series is CP Pistons' well-known line for racing applications, and these pistons feature a design optimized for strength and weight. The 1.120-inch wrist pin diameter is standard for many high-performance builds, ensuring compatibility with a wide range of connecting rods. Each piston in this set of eight is precision-machined to tight tolerances, which is crucial for maintaining proper compression and sealing under extreme cylinder pressures. This attention to detail helps ensure consistent performance and durability, even in high-RPM, high-horsepower environments.

When building or rebuilding a high-performance LS7 engine, selecting the right internal components is critical. These CP Pistons are designed to handle the stresses of racing and performance street use. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of this well-built set.
