I emailed ron at xr50s he said its better then appplied, doesnt make the rear end just stiffer, it gives it some travel. But not quite as good as say the high end shocks like ishock/works.
id save the extra couple bucks and buy an ishock without a rezzy. atleast you will get the extra travel, lift, and quality of an ishock. im probably going to do that myself :roll:
