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

Wiseco is well-known for making strong internal engine components, and these Professional Series pistons are a prime example. If you're building a serious engine for your Chrysler 300, Dodge Charger, or Jeep Grand Cherokee, these pistons are designed to handle the demands of heavy to severe duty performance applications. They are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for durability under stress.

These pistons feature a +4cc dome and a 3.917 inch bore, with a 1.2045 inch compression height and a 0.927 inch pin diameter. You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these are built for serious performance.
