Not any more. If the rules allow you to run your stock belts (full body vehicle, slower then 11.49in the 1/4), then you are exempt from the 2 year rule for aftermarket belts. The rule was changed sometime between the 2007 rule book,(I don't have the books in between) and the 2010 rule book. So the two year belt rule has been obsolete for at least 8 years. This is why you need to READ the current rule book.
