CP Piston Bullet Race Series Chevy LS3 4.070 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 high-performance Chevy LS3 engines. The 4.070-inch bore size is a common upgrade for LS3 builds, allowing for increased displacement when paired with the 3.622-inch stroke and 6.125-inch connecting rods. This specific combination is designed to handle the demands of serious engine work, whether you're building a track car or a powerful street machine.

CP Pistons uses a double-perpendicular pin boss design for added strength and rigidity in the pin bore area, which is crucial under high cylinder pressures. The included wrist pins are 5/16 inch thick-walled and made from case-hardened steel, ensuring they can withstand the significant forces generated during combustion. Each piston also features a pressure-balance groove, which helps to reduce blow-by and improve ring seal, leading to better power and efficiency.

This set includes eight complete pistons, each with its own set of rings and wrist pins, ready for installation. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications for proper installation and assembly procedures.
