Unlike other manufacturers and their claims of state-of-the-art processes, Steeda uses the latest technology directly from OE sources. Steeda doesn't use a cheap piggyback design like their competitors. The Steeda crank pulley features a one-piece nodular iron, injection molded rubber design. Special rubber materials were used for their ability to absorb the torsional vibrations and their ability to withstand underhood temperatures. Steeda has tested all their competitors underdrive pulleys and none are as precisely tuned as Steeda's underdrive pulleys.
Steeda underdrive pulleys are manufactured under ISO/TS16949, QS-9000 and ISO 9001 manufacturing certifications. Steeda worked directly with Ford to properly develop the best underdrive pulley set available. When you buy Steeda, you know you're getting high quality parts that will deliver maximum performance and durability. Order your 2005-2010 Mustang GT Steeda Underdrive Pulleys today.
added to hci/header/suspension project, high quality items, when you look at balancer beside oem, you wonder what ford was thinking...
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.
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 :)
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.
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!
