Manley Ford 4.6L/5.4L (3 Valve) 3.572in Bore -14cc Dish Extreme Duty Piston Set

These Manley Extreme Duty pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and performance under demanding conditions. This is crucial for engines like the Ford 4.6L and 5.4L 3-valve, especially when you're pushing them beyond stock power levels. The -14cc dish design is specific to certain engine builds, helping to achieve a desired compression ratio when paired with the right cylinder heads and camshafts.

Manley doesn't stop at the forging. They've incorporated proven cam and barrel skirt profiles, which are carefully machined to reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are held to exacting standards, which is key for ensuring a solid seal with your piston rings. This attention to detail means better combustion efficiency and more power getting to the wheels. For added durability, these pistons come standard with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that professional engine builders rely on for consistency.

When you're building a serious performance engine, especially a 3-valve Ford modular, you need components that can handle the stress. This set is designed for those who are rebuilding the top end and need pistons that offer both strength and precision. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
