Steeda is the leader in underdrive pulley design for the 4.6L engines. Steeda was the first to achieve SFI approval on our underdrive pulleys for all 4.6L engines. Our underdrive pulleys are the only pulleys engineered through our unique partnership in Ford's technology transfer program to have the proper torsional vibration dampening characteristics for your 4.6L engine. No other manufacturer can make this claim.

Don't be fooled by other manufacturer's and their "state of the art" process claims. Steeda uses the latest technology directly from O.E. sources. Steeda's crank pulley is a one piece nodular iron, injection molded rubber design. Not a cheap "piggyback" design like many of our competitors use. 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 acccessory 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!

Notes: 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.


Mid-2001 thru 2004 Pulley
Use Part #701-0003 for GT, 701-0004 for Cobra/Mach1

1996 thru Mid-2001 Pulley
Use Part #701-0001 for GT, 701-0002 for Cobra/Bullit


2003 Mach 1 DOES NOT use alternator pulley. Crankshaft U/D pulleys in very limited surplus, order now while supplies last.

Nice Bang for the Buck!
This was the 2nd Mod I did to my stock 99 Cobra in 2008 when I bought it. Right after CAI. Nice bang for the buck. I've put about 100K on them and they have performed flawlessly. Quality is Top-Notch. I would not trust any other Underdrive Pulleys.
