Ford Duratec Underdrive Crank Pulley – 146mm Trigger Ring

Description

For Ford Duratec and Mazda MZR Engines, an underdrive pulley is used to reduce accessory drive belt, water pump, and alternator speeds.

On competition engines, excessive alternator speed wastes power, and water pumps can cavitate at high speed thereby reducing cooling efficiency.

Machined from solid steel and features a corrosion-resistant coating for long service life. The Crankshaft key slot is machined but can also be used
on non-keyed cranks.
