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.
Maximum towing capacity is 17,980 lb; payload is 3990 lb. Choose a six-speed manual or a six-speed automatic transmission and a 383-hp 5.7-liter V-8; a 410-hp 6.4-liter V-8; or a 6.7-liter turbodiesel inline-six with 350 or 370 hp, depending on transmission.
