Manley Ford 4.6L/5.4L SOHC/DOHC (2v/4v)3.582in Bore 18cc Spherical Dish Extreme Duty Piston Set

Manley's Platinum Series pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle high performance demands. These pistons are specifically designed for Ford 4.6L and 5.4L SOHC and DOHC engines, featuring a 3.582-inch bore and an 18cc spherical dish. This dish volume is important for controlling compression ratio, especially when paired with specific cylinder heads and camshafts.

You'll find that Manley pays close attention to the details that make a difference in engine longevity and power. The cam and barrel skirt profiles are carefully engineered to reduce friction and wear on cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to very strict standards, which is crucial for achieving a solid ring seal. A good ring seal means better compression, less blow-by, and ultimately, more power from your engine. For added durability, these pistons come 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.

When you're building a high-performance Ford engine, whether it's a 2-valve or 4-valve setup, these Manley pistons are a solid choice. They are built to withstand the rigors of demanding applications, and they come with the kind of precision machining that helps ensure your engine build goes smoothly. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
