MotoBlue Underdrive Pulley Kit


for your 1994-2004 Mustang V6


What's an underdrive pulley?
An underdrive pulley is a replacement pulley that bolts up the same as stock, but has a different size (ratio) and material specifications intended to free up lost horsepower. By increasing the diameter of each accessory pulley and decreasing the size of the crank pulley, the speed at which the accessories are turning relative to engine RPM decreases.


No more power total, but more power sent to the wheels. As an additional benefit, the reduction in wear (less usage) on the accessories due to the lower duty cycles can extend the life of these parts.


For example, the alternator, power steering, water pump and air compressor rob horsepower from the engine. By replacing factory-sized crank balancer / pulley with a resized pulley, the accessories are slowed, resulting in more horsepower available to the drive wheels.


MOTOBLUE™ H.O. Series pulleys will increase horsepower up to 10 RWHP, and increase mileage by 2 to 3 MPG. MOTOBLUE H.O Pulleys are manufactured from billet steel, exceeding factory quality and are the only Pulley system available on the market today that use a new replacement balancer.


Installation: The kit includes all required components and hardware for a complete installation.
Tech Notes: Use of Harmonic Balancer Puller tool required for factory Harmonic Balancer removal.
