CP Piston Bullet Race Series Chevy LS3 4.065 Bore 3.622 Stroke 6.125 Rod Set Of 8

This is a set of eight CP Pistons Bullet Race Series pistons, designed for Chevy LS3 engines. Each piston features a 4.065 inch bore and is built to work with a 3.622 inch stroke and a 6.125 inch rod. These are forged pistons, meaning they start as a solid block of aluminum that is heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for high-performance applications where extreme stress is common.

The Bullet Race Series is CP Pistons' line of pistons built for demanding racing and performance builds. They incorporate advanced forging techniques and material science to create a piston that can withstand high cylinder pressures and temperatures. The 4.065 inch bore size is a common specification for LS3 builds, allowing for increased displacement when paired with the correct crankshaft and connecting rods. The 6.125 inch rod length is also a standard dimension for many LS performance builds, ensuring compatibility with a wide range of aftermarket crankshafts and connecting rod combinations. CP Pistons are known for their precision machining and attention to detail, ensuring each piston meets strict tolerances for optimal performance and reliability.

When building a high-performance LS3 engine, the pistons are a critical component. These CP Pistons are a solid option for those looking to push the limits of their engine, whether for track use or serious street performance. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to CP Pistons' technical documentation for specific installation guidelines and recommended clearances for your build.
