Wiseco Chrysler Small Block Mopar Gen III 6.1L Hemi 4.08 Bore 3.580 Stroke +5.5 CC Dome

If you're building a high-performance Mopar Gen III 6.1L Hemi engine for serious racing, these Wiseco Professional Series pistons are a solid choice. They're designed to handle the demands of heavy to severe duty applications, giving you the confidence to push your engine to its limits. Wiseco crafts these pistons from 2618 aluminum, a material known for its improved tensile strength, which is crucial when you're dealing with the high pressures and temperatures of a race engine.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, helping to keep combustion gases contained and power where it belongs. They also come with an ArmorGlide skirt coating. This coating helps reduce friction and resist seizure, contributing to both quieter operation and improved durability under stress. The fully machined crown ensures a clean combustion chamber shape, and forced pin oiling helps keep the wrist pins lubricated, a vital detail for longevity in high-stress builds.

This set includes eight pistons, each with a +5.5 CC dome, a 4.080-inch bore, and a 3.580-inch stroke. Remember, these pistons are not CARB approved and cannot be shipped to California. For a serious build, these Wiseco pistons offer a well-built foundation.
