This is a brand new 2.8 inch (71.12 mm) 6-rib pulley that I have to take a loss on. I installed it, turned on the engine, threw the belt, and realized that the offset was wrong for my blower (which meant this pulley stuck out too far and misaligned my belt). Oh well, can't dwell over it, just gotta sell it. So yes, this pulley has ZERO miles on it.
If you don't know about GripTec pulleys, here is the link to the one I am selling. Basically, the ribs and grooves are roughed up like sandpaper so there is less belt slip, less knock, and more boost.
