Sometimes a fear of heights can contribute to other fears, like aviophobia. Cognitive behavioral therapy (CBT) is sometimes helpful in treating cases of aviophobia. Aviophobia is a fear of flying.
Re: Increase towing capacity? Postby Z15 Â» Jul 01 2010, 5:59am. With that kind of weight you need to beef up the suspension big time. Air bags are not going to cut it, you need heavier springs, HD shocks, Load range E tires, bigger brakes.
A factory tow package usually includes heavy duty rear shocks/springs and an auxiliary transmission cooler in addition to the tow hardware itself, and sometimes they include a full size spare tire too. When a dealer installs it they just put on the hitch and wiring plug.
