Unlock the full potential of your 4.6L engine with Steeda, the industry leader in underdrive pulley design. Steeda takes pride in being the first to achieve SFI approval for all 4.6L engines, setting the standard for excellence. Our underdrive pulleys are the result of a unique partnership in Ford's technology transfer program, ensuring they possess the proper torsional vibration dampening characteristics for your 4.6L engine – a claim no other manufacturer can make.
While other manufacturers boast about their "state-of-the-art" processes, Steeda sets itself apart by using the latest technology directly from O.E. sources. Our crank pulley is a one-piece nodular iron, injection-molded rubber design – not a cheap "piggyback" design like some competitors. The selection of special rubber materials is based on their ability to absorb torsional vibrations and withstand underhood temperatures.
Steeda's underdrive pulleys are engineered to slow down accessory speed by approximately 25%, effectively reducing parasitic accessory drag on the engine. This drag reduction translates into a notable increase of up to 10 horsepower and improved gas mileage. Reclaim the horsepower and torque stolen by belt-driven accessories, and experience enhanced performance and fuel efficiency.
Notes: For 2001 model year Ford 4.6L engines, there was a mid-production change in the water pump design. The older style pump, produced from 1996 to mid-2001, had a longer shaft. In January 2001, the design of the pump was changed to a shorter shaft, necessitating a corresponding adjustment in the pump pulley design. Trust Steeda to deliver cutting-edge underdrive pulleys for your 4.6L engine – where innovation meets performance on every drive.
