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.
Although Chevy pickups are rated with a maximum tow capacity of 10,500 lbs., the 2500HD equipped with an Allison 6.6-liter Duramax diesel engine, six-speed automatic transmission, standard trailer hitch and a 4.10 axle ratio is capable of hauling up to 13,000 lbs., according to trucktrend.com.
