Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy LS1, LS2, and LS6 engines. The 3.903 inch bore and 3.622 inch stroke create a shelf stock configuration that's ready for demanding builds. Wiseco's Professional Series is designed for heavy to severe duty race applications where durability and consistent performance are critical.

These pistons feature a flat top design with a -2.2cc valve relief, and a 1.335 inch compression height. The fully machined crown and precision ring grooves, along with anti-detonation grooves and additional ring seal features, contribute to improved tensile strength and better ring seal. For added durability and reduced friction, the skirts are coated with ArmorGlide, which helps resist seizure and quiets operation. Forced pin oiling is also incorporated to ensure proper lubrication.

This kit includes a set of 8 pistons, ready for your next engine build. Please 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.
