They are an awesome shock, dunno if I'd use them on a softail again though, mine failed due to a combination of factors but after having it happen I'm gun-shy.
They work awesome, can be a bit of a chore to set up on a softail as the rear valves are awkward to access but once you have your sweet spot sorted they are top notch, many will say you can set them on the bench and they are spot on but with my time with them both on dynas and softails I beg to differ.
