Wiseco Chrysler HEMI 426 4.250in Bore 1.765 Compression Height +90cc Dome Top Pistons

If you're building a serious performance Chrysler 426 Hemi engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. They're designed to handle heavy to severe duty race builds, giving you the confidence to push your engine hard.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features to ensure excellent ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also making operation quieter. The fully machined crown and forced pin oiling are details that show these pistons are built for serious performance and durability.

This set includes eight pistons, each with a +90cc dome, a 4.250-inch bore, and a 1.765-inch compression height. Remember, these are intended for racing applications and are not CARB approved, so they cannot be shipped to California. If you're looking for pistons that can stand up to extreme use in your Hemi, these are a well-built option.
