Underdrive Pulley With Overdrive Alternator Pulley

For sale brand new in box motoblue 25% overdrive pulley and 32% overdrive alternator pulley. these are mint condition never installed. I decided i should get ahead on my mortgage for now instead of modding the truck. The crank pulley goes for 250 plus shipping brand new and the alternator pulley goes for 40 plus shipping. I was told with this combo you do not have to change your belt size due to the change in sizes using BOTH pulleys. i will let this go for 220 plus shipping. i will try and post pics tomorrow. These pulleys will increase mpg by reducing drag and also increase hp and torque greatly due to the slowing down of all the overdriven accessories (these trucks have alot of them) but keep your alternator fully charged all the time for the guys with the systems or bose or anything else that would keep you from normally using underdrive pulleys.
