Description
Regain Lost Power. Get back the power and torque your belt-driven accessories steal. As hard as it may be to believe, you can regain from 8 to 10 “free” horsepower with Steeda’s underdrive pulleys. These pulleys reduce engine parasitic drag from your accessories by about 25% and even improve fuel economy. 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.

Pretty good

Easy to install, nice product, I didn't see a big improvement in performance, but it does make the car run smoother, my engine vibrates way less all the way to the tranny, I can feel it thru the shifter. All

    Not recommend. Too expensive for a money.

    February 15, 2013

    Well you can fell something but... you'd better save some money for a supercharger or turbo kit Fitting quite easy but I had to crush my old alternator pulley teeth to dismantle it. I not recommend it. It's too expensive for a money.

    STEEDA U/D PULLEYS

    March 23, 2012

    When you buy this, I mean c'mon.. It's Steeda! Installed it on the Naval base I'm stationed at using the auto hobby shop. Very easy to install, but definitely had to pay close attention to the bolt installation and torque limits. Once installed it felt like my accessories were running lighter, but not much of a gain in HP, probably maybe 1 or 2 HP that's about it, but then again, I don't have a Super Charger to actually feel the difference. But still a good product to have!
