Description


Improve performance on your 2005-2010 Mustang GT with Steeda's Underdrive Pulleys. 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 accessory 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!

Hi I'm Gus with Steeda Autosports and today we're gonna talk about one of the most popular parts. Steeda Underdrive Pulleys for the 96-2010 Mustang. Steeda Underdrive Pulleys have two very important benefits. First, they increased rear wheel horsepower for improved performance and second, they also noticeably improved gas mileage. Underdrive pulleys provide an increase of 8 to 10 rear wheel horsepower. They accomplish this feat by reducing parasitic drag from driving the front engine accessories. This reduction in parasitic drag also results in an increase in fuel mileage. Here's how it works. Let's say you have a 300 flywheel horsepower engine and let's say you have 35 horsepower worth of total parasitic drag, so the engine makes 265 horsepower at the wheels. With underdrive pulleys you reduce the parasitic drag on the engine. So for simple math let's say you have freed up 10 horsepower. You still have a 300 flywheel horsepower engine, but the 10 horsepower you're no longer using to drive the accessories ends up going to the wheels, resulting in higher rear wheel horsepower. This improves overall acceleration. Our Steeda Crankshaft Pulley for our underdrive pulley kit was designed in conjunction with Ford Motor Company engineers and is manufactured by the same OE supplier that makes the factory OEM harmonic balancer. We're the only company that can make this kind of claim which results in a crankshaft pulley that properly dampens crankshaft harmonics to the entire rpm range. So if you're looking for improve performance, improve gas mileage or both you can't go wrong with Steeda Underdrive Pulleys.

Great Addition to My Mustang
I could tell these pulleys are a quality product just by how they were packaged. Also had a nice black finish on them. I had them installed by a shop so I wouldn't have to deal with the crank pulley puller. Not huge power gains, but definitely something you can feel. Car is more eager to rev and get in the power band. Also, I had no issues with engine temp in traffic with the a/c on a 90 degree day. Definitely a great addition to my 2010 GT.
