Wiseco Chevy LS Series -23cc R/Dome 4.200inch Bore Piston Shelf Stock Kit

If you're rebuilding the heart of your 1997-2004 Chevrolet Corvette for serious performance, a strong set of pistons is crucial. These Wiseco Professional Series pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy or severe duty race applications. The -23cc dish design is specifically engineered for certain LS engine builds, and the 4.200-inch bore size is a common specification for modified LS engines.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also come with forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. The crown is fully machined for accuracy, and the skirt is treated with an ArmorGlide coating. This coating helps reduce friction, resist seizure, and contributes to quieter operation, which is a notable benefit when you're pushing an engine hard.

This kit includes a set of 8 pistons, ready to be installed in your LS engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful build, always refer to the manufacturer's installation instructions for proper ring gap, pin fitting, and assembly procedures.
