Steeda Mustang Underdrive Pulleys | 2001-2004 Ford Mustang GT (701-0003)

Steeda’s crank pulley is a one piece nodular iron, injection molded rubber design. Special rubber materials were chosen for their ability to absorb the torsional vibrations and their ability to withstand underhood temperatures. Steeda’s underdrive pulleys slow down accessory speed by about 25% reducing parasitic accessory drag on the engine. This drag reduction results in an increase of up to 10 horsepower and increased gas mileage! Get back the horsepower and torque your belt driven accessories steal and start enjoying better performance and gas mileage today!

Please Note:

• Midway through the production run for the 2001 model year Ford changed the design of the water pump on the 4.6L engine. The older style pump produced from 1996 to mid 2001 had a longer shaft. In January of 2001 the design of the pump was changed to a shorter shaft. This necessitated a change in the design of the pump pulley.
• 2003 Mach 1 DOES NOT use alternator pulley.
