Manley Ford 3.5L Ecoboost 3.642in Bore 1.239in Comp Height -8.5cc Dish Extreme Duty Piston Set

Manley Performance is well-known for building strong engine components that professional builders trust. This set of Extreme Duty pistons is designed specifically for the Ford 3.5L EcoBoost engine, offering a 3.642-inch bore size and a 1.239-inch compression height. These pistons feature a -8.5cc dish, which is important for achieving the correct compression ratio in your build.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to handle high performance demands. They come with chrome moly wrist pins, and Manley's signature cam and barrel skirt profiles are used to help generate power while being gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is key for getting a good seal from your piston rings and making more power. Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that contributes to overall engine reliability and performance.

This set is considered an extreme duty piston, meaning it's built to withstand significant stress and heat. If you're rebuilding the engine in your Ford EcoBoost for high performance or heavy-duty use, these pistons are a solid option. Please note 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 details.
