CP Piston Bullet Race Series Chevy LS3 4.080 Bore 3.622 Stroke 6.125 Rod Set Of 8

Forged from 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for serious performance in Chevy LS3 engines. The 4.080-inch bore size and 3.622-inch stroke are designed to work with a 6.125-inch connecting rod, creating a robust combination for high-output applications. This set includes eight pistons, ready for your custom engine build.

CP Pistons uses a proprietary forging process for their Bullet Race Series, resulting in a strong yet lightweight piston. This design helps to reduce reciprocating mass, which can lead to improved engine response and durability under stress. The pistons are designed for a 4.080-inch bore, a common size for LS3 builds looking to increase displacement. They also feature a specific dish volume and valve reliefs that are engineered to work with the LS3 cylinder head and camshaft profiles, ensuring proper valve-to-piston clearance and optimal compression ratios when paired with the correct components.

When building a high-performance LS3 engine, attention to detail is key. These pistons are a solid foundation for a build aiming for significant horsepower. 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 the manufacturer's detailed specifications for correct installation, ring gap, and bearing clearances to ensure optimal performance and longevity of your engine.
