I am new to the whole shock thing but I know my 2011 Street Glide is leaking air. I know I can fix it easily by tracking the leak and either fixing a line or a shrader valve but my question is this: if I want to get rid of the air shocks altogether, are these progressive shocks the way to go? If so, I would assume someone makes a direct replacement? What about lower the bike just a tad? is that recommended. I rarely have a passenger as the girl friend has her own. Can someone give me some direction here. I think I would like to get this done before Sturgis. Thanks in advance!
