its cuz my truck has bags in the rear. I let the air out last week and doest sit so high now but i need it when i pull the bobcat or a shit load of rock or scrap. So they stayed filled most of the time. Its made to tow. if i had a leveling kit and tried to tow something it would ride bull dog and i hate that. IMO, a truck that rides bull dog, is like a dog with his tail in between his legs .
