Wiseco Chrysler 5.7L Hemi +21cc Dome 1.205inch Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who demand the best for their Chrysler 5.7L Hemi engines. If you're rebuilding your top end for heavy or severe duty, these pistons are designed to handle the stress and deliver consistent performance.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength over other materials. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to keep the pins lubricated under high loads. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly, all crucial for longevity in demanding builds.

This set includes eight pistons, each with a +21cc dome to help achieve a desired compression ratio. They feature a 3.917-inch bore and a 1.205-inch compression height, with a 0.927-inch pin diameter. This kit is designed to fit a wide range of vehicles, including models like the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee from various years. Please note that this part is not CARB approved and cannot be shipped to California.
