Manley Ford 4.6L/5.4L DOHC 3.572in Bore -11cc Dish Extreme Duty Piston Set

This set includes eight Manley Extreme Duty pistons, designed for Ford 4.6L and 5.4L DOHC engines. These pistons feature a -11cc dish, a 3.572-inch bore size, and are constructed from domestic 2618 alloy forgings, known for their exceptional strength and performance under demanding conditions. They also come standard with premium Chrome Moly wrist pins, which offer great durability for most builds.

Manley's signature cam and barrel skirt profiles are incorporated into these pistons. This design helps generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a better ring seal and ultimately, more power from your engine. Manley uses unique fixturing that allows them to machine the skirt and ring grooves in a single operation. This process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine efficiency and longevity.

These pistons are a solid choice for serious engine builders looking for robust components. While they come standard with Chrome Moly wrist pins, Manley also offers upgrades to 9310 and Turbo Tuff/DLC alloys for even greater durability in extreme applications. Remember that these pistons are not CARB approved and cannot be shipped to California.
