Wiseco Chevy LS Series -18cc R/Dome 4.125inch Bore Piston Shelf Stock Kit

If you're building a high-performance Chevy LS engine for serious racing or heavy-duty street use, a strong set of pistons is where you start. This Wiseco Professional Series piston kit is built for those demanding applications. Each piston is forged from 2618 aluminum, a material known for its improved tensile strength, making these pistons well-suited for the stresses of high-performance engines.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. The crown is fully machined for a clean finish, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated under load. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These pistons are designed to handle heavy to severe duty performance builds, offering a solid foundation for your engine project.

This kit includes eight pistons, designed for a 4.125-inch bore and featuring an -18cc dome. 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 assembly and break-in procedures.
