Manley 4.6L Ford Modular (2/4 Valve) 3.700in Bore 1.220in CD 18cc Dish Pistons - Set of 8

This set includes eight forged pistons designed for 4.6L Ford Modular engines, specifically the 2-valve and 4-valve variants. Each piston features a 3.700-inch bore, a 1.220-inch compression distance, and an 18cc dish volume. These pistons are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their exceptional strength and performance under demanding conditions.

Manley incorporates proven cam and barrel skirt profiles into 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 an enhanced ring seal and unlocking more power from your engine. For added durability, these pistons come standard with premium chrome moly wrist pins. Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate squareness between the ring groove and the skirt.

These pistons are a popular choice among professional engine builders and tuners who depend on Manley for superior performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
