2015 Ram 2500, 3500 HD Revised for Higher Payload Rating

The 2015 Ram 2500 HD and 2015 Ram 3500 HD pickup trucks are now even more capable, as the trucks’ optional 6.7-liter turbodiesel High-Output inline-six engine makes more power. In addition, a revision to the Ram 3500 equipped with a 6.4-liter V-8 has increased its payload capacity by 70 pounds.

Ram Trucks worked with engine supplier Cummins to program “more aggressive” turbocharger boost and fuel injection patterns, pumping up the High Output diesel’s torque output by 15 lb-ft , to a total of 865 lb-ft at 1700 rpm. Horsepower remains unchanged at 385 hp at 2800 rpm; a six-speed automatic transmission is standard.

Other chassis revisions mean that versions of the 2015 Ram 3500 HD with the standard 410-hp, 6.4-liter V-8 engine now have a maximum payload rating of 7390 pounds, an increase of 70 pounds compared to the peak figure for 2014 Ram heavy duty trucks. Maximum towing, which is achieved by the 2015 Ram 3500 HD with the aforementioned 6.7-liter High Output turbodiesel, is unchanged at 30,000 pounds.

Ram Trucks notes that its heavy duty towing and payload numbers conform to the new, more stringent SAE J2807 test criteria. While Ford and General Motors have released ratings for light-duty pickup trucks according to the new standard, Ram Trucks is the only company to apply SAE J2807 to its heavy duty models at this time.
