CP Piston Bullet Race Series Chevy LS2 4.045 Bore 4.000 Stroke 6.125 Rod Set Of 8

Forged from 2618-T61 aluminum, these CP Pistons Bullet Race Series pistons are built for high-performance Chevy LS2 engines. The 4.045-inch bore and 4.000-inch stroke combination is a popular choice for builders looking to increase displacement and power output from their LS platform. These pistons are designed to work with a 6.125-inch connecting rod, a common length for many LS engine builds, ensuring proper geometry and reduced side loading.

CP Pistons uses a proprietary forging process to create a strong yet lightweight piston. This specific Bullet Race Series design incorporates features like a deep valve relief to accommodate larger camshaft profiles and high-lift valve springs, crucial for preventing piston-to-valve contact in aggressive builds. The included wrist pins are also forged and sized appropriately for the application, ensuring durability under extreme stress. Each set comes with eight pistons, ready to be installed in your LS2 block.

When building a performance LS engine, the pistons are a critical component. These CP Pistons are a solid option for those aiming for significant power gains and reliability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or refer to the manufacturer's installation guide for specific clearance checks and assembly procedures to ensure optimal performance and longevity.
