Hey gang, if anyone is looking for 12" 440 Progressive shocks I found these;
http://underbid.com/action/display/item/780-1057850812/sku/28130.htmlI'm not sure if they are the H/D model but for $299 you could send them in to Progressive for the spring upgrade and still save quite a bit of cash. The manufacturer #4404240 says it will fit a Valkyrie but do your due diligence.
Update: I checked avaialblity of the part and they (mawonline) have all sizes from 11" to 13.5" in black (the fastest shocks) and chrome.
