Wiseco Chevy LS Series -3.2cc FT 3.903inch Bore Piston Shelf Stock

When you're rebuilding the engine for your 1997-2004 Chevrolet Corvette, especially for demanding performance builds, you want parts you can trust. This is a single, shelf-stock forged piston from Wiseco, designed for Chevrolet LS series engines. It features a 3.903-inch bore and a -3.2cc dish volume, meaning it's intended to work with specific cylinder head volumes to achieve a desired compression ratio.

Wiseco makes these pistons in the USA from 2618 aluminum, which offers improved tensile strength for durability under high stress. They come with precision ring grooves, an anti-detonation groove, and features to improve ring seal, all crucial for preventing blow-by and maintaining compression. The piston crown is fully machined, and it includes forced pin oiling to keep the wrist pin lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and makes the piston more resistant to seizing.

This piston is built to handle heavy to severe duty performance applications. Keep in mind that this part is not CARB approved and cannot be shipped to California.
