Maybe the question will mean more to another. I would assume you need to list a year as well since there is nothing in your signature or question for which model. I know that some people change shocks because aftermarket are better all around, some change on the street glide to a 13" vs. the 12" to get more travel.
I ride pretty hard, and just adjusted the rear and rebuilt the forks to my needs for my 14 SGS and my 17 SGCVO. I've never heard of anyone getting the dealer to "fix" the design/operation of the OEM shock.
