CP Piston Bullet Race Series Chevy LS2 4.030 Bore 3.622 Stroke 6.125 Rod 9.1 Set Of 8

When you're building a serious performance engine, especially a Chevy LS2, you need components that can handle the stress. This set of eight CP Pistons Bullet Race Series pistons is designed for just that. You get the pistons themselves, ready for installation into your LS2 block. They feature a 4.030 inch bore and a 3.622 inch stroke, with a 6.125 inch rod length, and a 9.1cc dish to help achieve your target compression ratio. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape, making them incredibly strong and resistant to the extreme pressures and temperatures found in high-performance engines.

CP Pistons is known for making well-built racing components, and this Bullet Race Series is no exception. The forged construction is key here; it creates a grain structure within the aluminum that's far more resilient to detonation and high cylinder pressures than cast pistons. This means you can push your LS2 harder, knowing your pistons are up to the task. The specific dish volume of 9.1cc is a notable detail, as it's carefully calculated to work with common LS2 cylinder head volumes and crankshaft stroke lengths to achieve a specific compression ratio, which is crucial for tuning your engine's power output and efficiency. These pistons are built to be a direct fit for LS2 applications with the specified bore and stroke, simplifying the assembly process for experienced engine builders.

Because these are performance pistons intended for demanding builds, it's important to ensure they are paired with the correct supporting components. This includes appropriate connecting rods, a crankshaft with the specified stroke, and cylinder heads that complement the piston dish volume to achieve your desired compression. Always refer to the manufacturer's detailed installation instructions and consult with your engine builder to confirm all specifications and assembly procedures. Please note that these pistons are not CARB approved and cannot be shipped to California.
