Wiseco Chrysler 5.7L Hemi +4cc Dome 1.205inch Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious engine builders working on heavy-duty or severe-duty race builds for a range of Chrysler, Dodge, and Jeep vehicles equipped with the 5.7L Hemi engine. If you're rebuilding the top end of your 5.7L Hemi, these pistons are designed to handle the stress of high-performance use.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. They feature a +4cc dome to help achieve a specific compression ratio, and the crown is fully machined. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly. Forged pin oiling is also included to ensure proper lubrication to the wrist pin.

This set includes eight pistons, designed for a 3.917-inch bore and a 1.205-inch compression height, with a 0.927-inch pin diameter. They are a shelf stock kit, meaning they are designed to fit a range of common 5.7L Hemi applications, including vehicles like the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee. Please note that these pistons are not CARB approved and cannot be shipped to California.
