I hate that they all tear and don't stay in place.I have the PRP neoprene shock covers they fit tight and look good but tear a little easier than I had expected. I have run covers for at least 30 years and feel they protect the shaft and seals from damage and have never found a down side. I guess the worst thing is pulling them off and checking for anything that got by and you definitely don't have to do it every time you wash.
