Decent quality. Nice fit
I'm giving this product 4 of 5 based solely on the fact that they can't be bothered to include THREE nuts needed (two different thread sizes). It's just dumb that you buy something like this and then have to count on already having, or needing to go out and purchase these essential pieces of hardware to install the product.
Less than half an hour to install fit my Fatboy perfectly.
