If you've ever changed a tire with a stubborn wheel nut. What the first thing you do? You put an extension on the lug wrench. Boom, it gives. The wheel nut didn't magical loosen while you were looking for an extension. You increased your leverage point by extending the handle of the lug wrench. It's the same principle just applied differently.
To my other post. Companies don't have different molds for longer shafts. They use a standard shaft and add an extension. So while it does feel different it's not a different shaft.
