Wiseco Chevy LS Series -32cc Dish 1.115x4.070 Piston Shelf Stock Kit

Starting with the material, these Wiseco pistons are forged from 2618 aluminum, a well-known choice for its improved tensile strength, making them a solid option for serious engine builds. This particular set is designed for Chevrolet LS series engines, featuring a -32cc dish and a 4.070-inch bore, with a 1.115-inch compression height and a 0.927-inch pin diameter. They are built to handle heavy to severe duty performance applications, meaning they're intended for engines that will be pushed hard, like in racing or high-performance street builds.

Wiseco packs these Professional Series pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, which helps maintain compression and prevent blow-by. 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 stress. Plus, the ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all important factors when building a high-performance engine.

This kit includes a set of 8 pistons, ready for installation in your 1997-2004 Chevrolet Corvette, 1998-2002 Camaro, 1998-2002 Pontiac Firebird, or 2004 Pontiac GTO. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed instructions and consider pairing these with appropriate connecting rods and a full engine rebuild plan.
