Wiseco Chrysler Small Block Mopar Gen III 6.1L Hemi Drop In Replacement 4.055 Bore 3.580 -8 Volume

What you get in this kit are eight forged pistons from Wiseco, designed for Chrysler's 6.1L Hemi engines. These pistons are built to handle the demands of serious racing and heavy-duty performance builds. They feature a 4.055-inch bore and a -8cc volume, making them a drop-in replacement for your existing pistons when you're looking to step up your engine's capability.

Wiseco makes these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for durability under stress. You'll find precision machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep things running quieter. The fully machined crown and forced pin oiling are also part of the package, all aimed at ensuring these pistons can withstand severe duty applications.

Because these are designed for high-performance racing, they are not CARB approved and cannot be shipped to California. If you're building a serious Hemi engine and need pistons that can take a beating and keep performing, this set from Wiseco is a solid option.
