Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston kit is built for serious racers and builders who need dependable parts for heavy-duty race builds. These pistons are designed to handle the demands of severe duty performance, helping you push your engine's limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for durability under stress. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown of each piston is fully machined, and they come with forced pin oiling to ensure proper lubrication. For added performance and longevity, these pistons also feature an ArmorGlide skirt coating that helps resist seizure, reduce friction, and operate more quietly.

This kit includes a set of 8 pistons, each designed for a 4.600-inch bore with a 1.120-inch compression height and a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
