Superior Materials. Steeda underdrive pulleys are manufactured from nodular iron, and far exceed the quality of the stock factory pulleys. The one-piece crankshaft pulley uses a high-tech injection molded bonded rubber damper, making it far more durable than other manufactures "piggyback style" underdrive pulleys.
SFI Approved. Steeda underdrive pulleys are SFI approved for use by all major race sanctioning bodies.
Application. These Steeda Underdrive Pulleys are specifically designed for use on the 2001 SVT Cobra and 2003 to 2004 Mach 1 Mustangs equipped with the DOHC 4.6L V8.
Technical 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.
