Get back the power and torque your belt-driven accessories steal. Bolt on 8-10 "free" horsepower with Steeda's underdrive pulleys. These pulleys slow down your accessories about 25%, reducing the drag on your engine. They even bump up gas mileage. Our pulleys are manufactured from billet steel, exceeding factory quality. They're also SFI race approved. The one-piece crankshaft pulley uses a high-tech injection molded bonded rubber damper, making it far more durable than "piggyback style" underdrive pulleys.
Fits 2001 Cobra Mustangs and 03 - 04 Mach 1 (Mach1 does not use Alt. Pulley)
