Dodge underdrive pulley with great condition belt. I purchased this under drive pulley from i think Summit about 2 years ago. The belt is a goodyear gaterback belt sized to compensate for the smaller pulley on a 1999 5.2l, I'm not sure if the belt is correct for other motors. Using this underdrive pulley reduces the speed of all of your engine accessory 25% and was advertised as reducing load on the motor by 15hp on my 5.2l. I sold my pickup and removed all of the aftermarket goodies so now you can pick them up for your vehicle. The manufacturer advertises this pulley as fitting Dakota, Ram and Durango with the 3.9 5.2 or 5.9 motors. Since this product reduces load and is not technically a "power adder" you can use this to increase your fuel economy. Asking $50 shipped to continental USA
