OEM Ford Stamped Steel Trigger Wheel for 4.6L / 5.4L Engines

The Cast Trigger Wheel found in the 2000 and earlier models is a weak link and should be replaced with this Stamped Steel Trigger Wheel. This OEM part is found in 2001 and later 4.6L / 5.4L Engines and can be used on all 2V, 3V and 4V Engines. Earlier models that originally came with the thicker, cast wheel will need to change to the newer style 1 piece Crankshaft Sprocket with the built in spacer. 

For those using the TFS Adjustable Crankshaft Gears, we highly recommend using this Trigger Wheel. The supplied spacer from Trick Flow will be installed between the front of the Crankshaft Sprockets and the Trigger Wheel.
