Manley Chrysler 5.7L Hemi 90.9mm Stock Stroke 3.937in Bore -12cc Dish Standard Platinum Pistons

This set includes eight Manley Platinum Series pistons, designed for Chrysler 5.7L Hemi engines. These pistons feature a 3.937-inch bore and a -12cc dish, intended for a stock stroke application. They are built using domestic 2618 alloy forgings, known for their strength and ability to handle demanding performance conditions. Each piston comes with premium chrome moly wrist pins, and the set is designed to work with your existing engine components.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps generate substantial power while also being gentle on your cylinder walls, contributing to longer engine life. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a better ring seal and unlocking more power from your engine. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring groove stays perfectly square to the skirt for optimal performance.

These pistons are a solid choice for anyone rebuilding or upgrading their 5.7L Hemi engine. They are not CARB approved and cannot be shipped to California. Please refer to the manufacturer's installation instructions for details on proper fitment and assembly.
