Are you sure your shocks are bottoming out, and not topping out? I had a set of lowered shock on my '09 Street Glide that I couldn't stand until I tracked down the actual cause. I kept adjusting firmer, but was only making the ride harsher. What I found (with the help of a Flip video camera and time) was the shock was topping out, not bottoming out (feels/sounds the same) There is no replacement for shock travel!!! I went back to the factory length shock and all was well. They were Progressive 440's and they swapped them out no problem after about 45 days of ride time. I don't really have a height issue, so it was a no brainer for me. I did end up with the Heavy Duty versions, because Im 265lbs, by my self and 400-420 with BSR and TP. Just something to check before you lay out more cash.
