Manley Ford 4.6L/5.4L SOHC/DOHC (2v/4v)3.572in Bore 18cc Spherical Dish Piston Set

Starting with 2618 alloy forgings, these Manley pistons are built for serious engine work in your Ford 4.6L or 5.4L 2-valve or 4-valve engine. The 3.572 inch bore size and 18cc spherical dish are specific dimensions that matter when you're rebuilding or upgrading your engine's core components. These aren't just off-the-shelf parts; they're designed to handle the demands of performance builds.

Manley uses a proven cam and barrel skirt profile on these pistons. This design helps manage piston-to-wall clearance, which is crucial for reducing noise and wear while still allowing the piston to expand properly under heat. The ring lands and grooves are machined to strict standards, which helps ensure a solid seal for the piston rings, leading to better compression and more power. They also come with chrome moly wrist pins, known for their strength, and for some applications, Manley offers upgraded wrist pin materials for even more durability.

The manufacturing process itself is notable. Manley's unique fixturing allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the skirt, which is essential for optimal ring seal and overall engine health. If you're building a performance engine for your F-150, F-250, Mustang, or Ford GT, these pistons are a solid choice for reliability and power.
