Ford 4.6L 
Harmonic Damper

Professional Products 80011 PowerForce harmonic damper balancer.

Fits 2005-2009 Ford 4.6L engines.

The dimensional duplicate of the O.E. damper used on the 2 valve engine.

If used on a 4 valve engine, the accessories (alternator, A/C, etc.) will rotate 3% slower than stock. Normally this is not a significant amount. This is due to a slightly different diameter of the damper.



These dampers do not have timing marks on them but they do have a notch in the back rim of the damper indicating TDC.

Made of nodular iron.

Painted semi-gloss black.

Damper has less than .005" runout.

Weights in at 6.10 pounds.

Great for high performance street engines or stock replacement applications.
