I put the HD Low Profile shocks on my 09 Road Glide and the ride is somewhat harsher. I haven't tried more air pressure (currently have 16 lbs). I weigh 180 and wife is 110. I had previously tried the Progressive 412 shocks and experience a harsh ride. I believe this low profile shock is the same shock configuration as the Street Glides and the new Road Glides. Can't believe Harley would use a shock that is so rough. Am I the only guy experiencing this?? Another question --- how does lowering only the rear affect the steering? I'm sure I read somewhere on this forum that it affected the steering but can't finds that thread. Thanks BTW: I love the ROad Glide and the sharky fairing!!
