This CP-Carrillo Bullet series pistons for LS7 engines with a 4.130-inch bore and 4.000-inch stroke are engineered for high-performance applications. These pistons feature a dish top with a -25cc crown volume, resulting in a compression ratio of approximately 9.5:1 when paired with 70cc combustion chambers. Manufactured from 2618 aluminum forgings, they are suitable for nitrous oxide, supercharged, or turbocharged setups. The pistons come with a premium ring set, including a 1.5mm steel gas nitride top ring, a 1.5mm Napier second ring, and a 3.0mm oil ring. Wrist pins measuring 0.927 inches in diameter and 2.250 inches in length are included. These pistons are compatible with 6.125-inch rod lengths and are designed to withstand the demands of high-horsepower LS7 builds.
