Wiseco Chrysler HEMI 426 4.280in Bore 1.765 Compression Height +90cc Dome Top Pistons

If you're rebuilding a legendary Chrysler 426 Hemi engine for serious racing, you need pistons that can handle the extreme demands. These Professional Series forged pistons from Wiseco are built from the ground up for heavy to severe duty performance applications. They are engineered, forged, and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to withstand the intense pressures of racing.

Wiseco has packed these pistons with features to ensure top performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown is ready for your build, and forced pin oiling helps keep things lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This is a set of 8 pistons, each with a +90cc dome, designed for a 4.280-inch bore and a 1.765-inch compression height.

These pistons are designed for builders who are serious about performance and aren't cutting corners. They are a well-built option for those pushing their Hemi engines to the limit. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
