I have 58k on mine now and still have the stockers, I have never been happy with the ride though. I am planning on changing them this spring when its warmer (-15° is too cold to work in an unheated pole barn, changed my exhaust at that temp, Never again).
I was looking at the Monroe Reflex shocks. Anyone have any experience w/ these? I know monroe generally makes a nice product, but I have no experience with the Reflex shocks. They are much cheaper than bilstiens as well (~$40 ea. from rock auto)
