Mustang GT 3V 4.6L V8
Steeda Underdrive Pulleys
Underdrive pulleys are a great way to regain horsepower lost to your Mustang GT's belt-driven accessories. But, you have to be careful. Poorly manufactured underdrive pulleys can cause problems big and small, from dips in alternator voltage to engine damage. Steeda's underdrive pulleys allow you to safely return up to 10 horsepower to its rightful place under your right foot.
Steeda's 2005-2010 Mustang GT underdrive pulleys improve fuel economy and boost power by slowing down accessory speed by about 25%, reducing parasitic drag on the engine.
Steeda is the industry leader in underdrive pulley design for Ford's 4.6L V8. Steeda engineers their underdrive pulleys with insight gained from their technology transfer program with Ford. Steeda's Mustang underdrive pulleys have the proper torsional vibration dampening characteristics for the 2005-2010 Mustang GT's 4.6L engine, ensuring safe operation. These Mustang underdrive pulleys are SFI certified.
Steeda's crank pulley is a one piece nodular iron, injection molded rubber design. It is not a cheap "piggyback" design like many other manufacturers offer. Steeda's special rubber materials were chosen for their ability to absorb the torsional vibrations and withstand under hood temperatures.
Keep in mind:
Underdrive pulleys are for naturally aspirated Mustangs only. They will actually decrease power on supercharged Mustangs. If you have a supercharged Mustang check out an Overdrive pulley.
