Wiseco Chrysler 6.1L Hemi 5.5cc Dome 1.220 CH Piston - Set of 8

If you're building a serious performance engine for your Chrysler 6.1L Hemi, this set of eight forged pistons from Wiseco is designed to handle extreme conditions. These aren't your average pistons; they're crafted for heavy to severe duty race applications where durability and consistent performance are critical. Wiseco has packed these Professional Series pistons with features that serious builders expect, ensuring your engine can withstand the demands of competition.

Each piston starts as a forging from 2618 aluminum, giving them improved tensile strength over cast aluminum. They're then machined in the USA with precision ring grooves, an anti-detonation groove, and other features to enhance ring seal. You'll also find a fully machined crown for accuracy and forced pin oiling to keep the wrist pin lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and quiet down operation, making for a smoother running, more durable engine.

This set includes eight pistons, each with a 5.5cc dome and a 1.220-inch compression height, designed for a 4.060-inch bore. Remember, these pistons are not CARB approved and cannot be shipped to California. For builders aiming to push the limits of their 6.1L Hemi, these Wiseco pistons offer a well-built foundation for a high-performance engine.
