Wiseco Chevy LS Series -25cc Dish 4.005inch Bore Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle heavy to severe duty use. If you're rebuilding the top end of your 1997-2004 Chevrolet Corvette for demanding performance, these pistons are designed to meet that challenge.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling to keep things lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This kit includes a set of 8 pistons, each with a -25cc dish and a 4.005-inch bore. They are designed to fit directly into your LS engine. Keep in mind these are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and pins, which are included with this kit.
