Wiseco Chrysler 5.7L HEMI +6.55cc Dome 1.220CH 3.917in Bore 3.580 Stroke Piston Kit

This is a set of eight forged pistons from Wiseco, designed for Chrysler 5.7L HEMI engines. You get the pistons themselves, ready to be installed in your build. These pistons are made from 2618 aluminum, a well-known material for its strength, which is crucial when you're pushing an engine hard. They feature a dome design with a +6.55cc volume, a 3.917-inch bore size, and a 3.580-inch stroke, all specific to certain engine configurations.

Wiseco has put a lot of thought into the details here. The ring grooves are precisely machined to ensure a good seal, and there are features like anti-detonation grooves to help prevent damage under high stress. A notable feature is the ArmorGlide skirt coating, which is applied to reduce friction between the piston and cylinder wall, helping to prevent seizure and making the operation quieter. The crown of each piston is also fully machined, and they incorporate forced pin oiling to keep the wrist pins well-lubricated.

These pistons are built for demanding applications, meaning they're intended for engines that will see heavy use or racing conditions. If you're rebuilding a high-performance 5.7L HEMI and need components that can handle significant stress, this set from Wiseco is a solid option. Keep in mind that these are not approved for use in California due to CARB regulations.
