I don't have one, and I'd PM the folks Dino mentioned for insight into that particular frame setup before doing anything else. Remember that this can be a problem with any shock that doesn't have a way to make the compression dampening progressive. Depending on the year of Reign, there may not be many shock options that will fit in the hole. If you're stuck with shocks that don't run resevoirs due to space constraints, you might want to look into the Marzocchi Rocco R air(if it will fit). It's a pretty basic shock with no platform, but you can adjust it's bottom out resistance which might help in your situation. Another option would be to call the guys at Garageworks suspension, or Push and see if they have any recommendations/solutions for your application. Chris
what year and model do you have? rocco r would not be a good choice as no platform and high volume will only increase how linear the rear suspension already is. If you're running a fox shock, switch out the air can to the smallest size. Push Industries sells the small air can and new bottom out bumper as options for their tunes.
