Weighing in at just 10lbs, this revised crankshaft pulley will remove over 12lbs of rotating mass over the factory 22lb 2007 GT500 crankshaft pulley.
Designed by Ford engineers, it has the proper harmonic characteristics for the engine as well providing all the benefits of reduced rotating mass such as slightly improved throttle response and less stress on the front end of the crankshaft.
Highly recommended for all 2007 GT500 owners. This pulley is O.E. on 2008-09 GT500 models. It is an upgrade from stock on 2007 models only. For 2008-09 models it is a perfect service replacement for the O.E. pulley on high mileage cars as well as new engine builds.
