Wiseco Chrysler 6.4L Gen III Hemi Apache 4.090in Bore -8.00in CC Dome 1.210 CH - Set of 8

If you're building a serious performance engine for your Chrysler 6.4L Hemi, these Professional Series forged pistons from Wiseco are a solid choice. They're designed for the demands of heavy to severe duty race applications, meaning they're built to handle a lot of power and stress. This set includes eight pistons, each with a 4.090-inch bore size, a dome volume of -8.00cc, and a compression height of 1.210 inches.

Wiseco makes these pistons in the USA from 2618 aluminum, which is known for its improved tensile strength, making them well-built for high-performance use. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and they also come with forced pin oiling to keep things well-lubricated. Plus, they include an ArmorGlide skirt coating that helps reduce friction and noise, and resists seizure.

Because these are forged pistons, they are significantly stronger than cast pistons and are essential for high-horsepower builds. This set is designed to withstand the rigors of racing, so you can push your engine's limits. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
