For LS7 engines with a 4.125-inch bore and a 4.000-inch stroke, CP-Carrillo offers a Bullet Series flat-top piston designed to enhance performance. These pistons are crafted from 2618 alloy, known for its high strength and durability, making them suitable for high-performance applications, including those utilizing nitrous oxide, superchargers, or turbos. The flat-top design features a -4.6cc volume, contributing to an 11.1:1 compression ratio when paired with LS7 12° heads. Each piston includes a 1.5mm steel gas nitride top ring, a 1.5mm Napier second ring, a 3.0mm oil ring, and .927 x 2.250-inch pins with a .180-inch wall thickness. The special skirt design reduces piston noise, enhancing overall engine performance.
