Sorry, this item has become obsolete.
Includes new alternator, water pump, and crankshaft pulleys. Made specifically for the '91-93 5.0L Tbirds and Cougars.
An easy bolt on that yields 12 to 15 HP. Less parasitic drag from your accessories means more power can go to the rear wheels. Note that Mustang pulley sets will NOT work on your Tbird. The pulleys are different!
These are no gimmick...they work like a charm!
