Wiseco Chevy LS Series -25cc Dish 4.030inch Bore Piston Shelf Stock Kit

When you're building a serious LS engine for your 1997-2004 Chevrolet Corvette, you need parts that can handle the stress. This Wiseco Professional Series piston kit gives you a set of eight pistons, each with a -25cc dish and a 4.030-inch bore, designed for heavy to severe duty performance applications. These aren't your average pistons; they're built from 2618 aluminum, forged and machined right here in the USA for improved tensile strength.

Wiseco put a lot of thought into the details that make a difference. You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal, all working together to keep combustion contained. The piston crowns are fully machined, and they feature 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 also resisting seizure, making for a smoother, quieter operation even under demanding conditions.

This kit is intended for builders who are pushing their LS engines hard. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
