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!
