It's no different than say wheels on you truck. If you run aluminum spun wheels then you will need to just keep up on them when it is necessary. If things start looking dull then repolish them with aluminum polish.
I read all over the place on here that you could run the stock shock up to a +4, and if you went to a +6 then you needed to revalve and or re-spring the shock. Because if what you are saying is true then that throws another monkey wrench into my +4 or +6 swinger, cub motored shee (hell-of-a-description ha). I also heard that you can't jump with a +6 or you'll tear it up or break it.
Don't mean to contradict, but what up with that.............? :beer:
