CP Piston Bullet Race Series Big Block 4.605 Bore 4.250 Stroke 6.535 Rod 1.120 Set Of 8

This is a set of eight CP Pistons Bullet Race Series pistons, designed for big block engines. You get the pistons themselves, ready to be installed in your build. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process makes them incredibly strong and durable, which is exactly what you need when you're pushing a big block engine hard.

The specifications here tell a story about performance. With a 4.605-inch bore and a 4.250-inch stroke, these pistons are built for displacement and power. The 6.535-inch rod length is also a key measurement, working in conjunction with the crankshaft and piston to determine the engine's overall geometry and how it breathes. The 1.120-inch compression height is also important, as it dictates how the piston sits in the cylinder relative to the deck surface, directly impacting your compression ratio. These are precision components for a serious engine build where reliability and performance under stress are paramount.

Because these are race series pistons, they're intended for high-performance applications. It's important to note that these are not CARB approved and cannot be shipped to California. If you're building a powerful big block for the track or serious street performance, these pistons offer a well-built foundation. Always refer to the manufacturer's detailed installation instructions and specifications for your specific engine combination to ensure proper fitment and optimal performance.
