Wiseco Chevy LS Series -25cc Dish 3.905inch Bore Piston Shelf Stock Kit

If you're building a high-performance Chevrolet LS engine for serious racing or severe duty applications, Wiseco's Professional Series forged piston kit is a solid choice. This kit is specifically designed for the 1997-2004 Chevrolet Corvette, but also fits other LS-powered vehicles like the Camaro, Firebird, and GTO from the late 90s to early 2000s. These aren't your average pistons; they're built from the ground up to handle extreme stress and deliver reliable power when you need it most.

Wiseco crafts these pistons from 2618 aluminum, a well-known material for its improved tensile strength, making them well-built for demanding conditions. They feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. The crown of each piston is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated under high loads. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is crucial for longevity in a race engine.

This kit includes a set of eight pistons, each with a -25cc dish and a 3.905-inch bore, ready to be installed in your LS engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these Wiseco pistons offer a strong foundation for pushing your LS engine's limits.
