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 1996 to Mid 2001 4.6L V8 GT Mustangs and reuse the stock belt.

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.

crank pulley bolt do u need to get a new one.

Bell Year: 1999 Model: GT

  • No you do not as long as you have the stock one still. It comes with a long one for install but do not put it all the way in. Go by the instructions for that. Just make sure to get the bolt torqued to spec and you should be good.

    Good pulleys

    these pullies are much better then the BBK option, go with this if your considering this mod. Steeda pullies come with a calibrated counterwieght where the bbk cheaper ones do not, they have you bolt up your old counterweight to the bbk pullies = old + new parts that don't mesh wel and don't put down as much power as the steeda, spend the extra 50 buck and do it right.

    steeda pulleys

    these underdrive pulleys are the way to go!! they are by far the best pulleys available for your mustang. only downfall of these pulleys is if you have a big amp and subs in your car you will need a bigger alternator. but other wise i give these pulleys a thumbs up!

    A Must-Have product for your automatic

    I was skeptical before purchase thinking there wouldn't be an improvement in power or fuel economy. But after purchase and install, I immediately "felt" the horsepower difference and now my buddy is jealous. Fuel economy is not hurting my wallet anymore. Removal & installation was easier and in minutes with an impact gun for the alt and crank. I would rate this Steeda product 10 stars and would not recommend other brand pulleys! Thanks AM, for the timely delivery!

    WOW

    I replaced my stock pulleys with some Steeda under drive pulleys and OMG you can't imagine how it feels after the install. Runs great and feels like a gave it life again.. good performance gain and i paid $75 for the install took over 2hrs but well worth the wait.

    easy install

    i think it took me more time renting the tools i needed than installing them. did it by myself in like 40mins (no breaks). i watched the video about 100 times. lol you can tell a little HP gain but revs way more freely. can wait to go to the track.
