Mustang Steeda Underdrive Pulleys GT 2005-2010

Part Number: UP31

Steeda Part Number: 701-0005-A

STEEDA Underdrive Pulleys for all 2005-2010 GT Mustangs.

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. Steeda's 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!

Dont 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!

Product Benefits:
- Tuned to the Proper Frequency of the 4.6L Engine
- Reduced Accessory Parasitic Drag
- Increased Rear Wheel Horsepower
- Increased Gas Mileage
- Smooths Out Engine Vibration

The steeda UDPs are the closets to OEM quality. No other brand can match the attention to detail. Challenging to install if you do not have air tools. Only worth 8rwhp on manuals and 6rwhp on automatics with same torque gains on dyno. Noticed gas mileage improvement of almost 1 mpg.

Thank you CJ Pony for your great pricing and excellent service. I installed these pulleys on my 2010 GT 5 speed and gained an average of 3.8 miles per gallon and by far the most noticeable power gain. The engine revs much quicker and plants you in the seat like a jet fighter.

GREAT PRODUCT

When I bought these, CJ had special pricing on it and I got them for cheaper than I've seen anywhere else!! Shipping was fast! Now about when I had them installed... Felt a noticeable difference in power. Really woke the low end torque up too! I definitely recommend these :)

Feel the gain

Easy to install. Only had to remove CAI tube. A Chrysler style harmonic puller is a must. Noticeable power increase. Acceleration stronger and snappier. Quality, simple, inexpensive and good performance mod. Should increase MPG, too!
