Manley Ford 4.6L Modular V8 Piston Set - 3.700in Bore 1.200in CH, -18.00 CC

If you're rebuilding the engine in your Ford 4.6L Modular V8 for serious performance, a strong set of pistons is where you start. These Manley pistons are forged from 2618 alloy, a material known for its strength and ability to handle the stresses of high-horsepower applications. They feature a -18.00cc dish, which is important for setting your compression ratio when paired with specific cylinder heads and head gaskets.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them run true and reduces wear on your cylinder walls, even under heavy load. The ring lands and grooves are machined to tight tolerances, which is crucial for getting a good seal from your piston rings. A good ring seal means more power and better efficiency. These pistons also come with tool steel wrist pins for added durability, and select part numbers feature a moly skirt coating to further reduce friction and wear.

When building a performance engine, attention to detail matters. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in the same setup, ensuring they are perfectly square to each other. This level of precision helps ensure your engine runs smoothly and reliably. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
