Get back the horsepower and torque your belt driven accessories steal and start enjoying better performance and gas mileage today!
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!
Steeda 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.

These are very nice quality units, I've only used Steeda on any of my cars and recommended them to my customers for years.
Don't buy the no name junk some places sell, these are the best and at very good price!!
This is the balancer and pulley setup I recently used on a FR500S Mustang Challenge car, of course not in the challenge anymore but a different NASA class. We built a forged 302ci 3-valve with Stage 3 heads,FRPP manifold, TB and cams, C&L racer air intake, and Steeda underdrives.
The entire assembly was balanced at Hesco's machine shop using these UDP's and everything was right on the money. This car spins to 7300 rpm's and I could tell you the horsepower but its hush hush due to his class, I will say that its ATLEAST 370 N/A rwhp
Thanks, Doug
