Well as they say, "to each his own". As the lowering blocks will drop the rear 2" to 2-1/4", and the fender gets really close to the swingarm especially on the right side, I think some carefull measuring might be in order. I'm sure the drop can be made but you're getting into the area of maxium up-travel on the swingarm at that point. Should it bottom-out or bind up at that really low stance I would think the ridability would be severely compromised.
We engineered the brackets to work with the stock shocks to preclude having to drop $400-$500 large to get our bikes lowered. The stock shocks work quite well, at least for us.
As to the "harley "shocks, they don't know or care what kind of bike they're mounted on. As the TA/SM weigh app. the same as a "Sportster" those should work should you decide to try them.
