The Bullet series pistons for LS1, LS2, and LS3 engines are designed for high-performance applications, offering durability and strength with 2618 aluminum forging. They feature a 4.070-inch bore and a 3.622-inch stroke, making them ideal for performance builds. The flat-top design with a -3.0cc crown volume results in a compression ratio of ~10.3:1 when paired with 68cc combustion chambers. These pistons come with a premium ring set, including 1.5mm steel gas nitride top, 1.5mm Napier second, and 3.0mm oil rings, along with 0.927-inch wrist pins (2.250 inches long). Compatible with 6.125-inch rod lengths, they are designed to handle nitrous, turbocharged, and supercharged setups, making them a reliable choice for high-horsepower LS builds.
