Dodge introduces the new 2005 Dodge Ram 3500 Box-Off 4x2 dual-rear-wheel model, according to a statement released May 16 from Dodge. Dodge Ram 3500 Box-Off 4x2 Dually is available in regular and Quad Cab models and is packaged with full-size Ram capability. The truck offers commercial work-truck customers easy upfit capability thanks to frame rail rear spacing of 42 inches, according to Dodge. Offered in ST, SLT and Laramie models, the newest Box-Off 4x2 Dually provides heavy-duty towing and payload capability with a maximum 11,000 lb. Gross Vehicle Weight Rating (GVWR), maximum payload capability of 5,550 lbs., and best-in-class maximum Gross Combined Weight Rating (GCWR) of 23,000 lbs, Dodge says. The Dually is available with the 5.7-liter HEMI V-8 or the 5.9-liter Cummins Turbo Diesel. The standard 5.7-liter HEMI V-8 engine produces 345 horsepower and 375 lb.-ft. of torque at 4,400 rpm. Generating 325 horsepower and a class-dominating 610 lb.-ft. of torque--the most torque available in a production heavy-duty box-off model, according to Dodge-—the Cummins Turbo Diesel has overhaul intervals of 350,000 miles, providing more than a 100,000-mile advantage over the competition. Other features include 17-inch wheels and tires, a large 35-gallon fuel tank, cab-to-axle dimensions of 57 inches and an adjustable fuel filler kit allowing upfitters flexibility in locating the fuel fill to meet end-users' needs. Oil change intervals are 15,000 miles versus 7,500 for the competition. The Dodge Ram 3500 Box-Off 4x2 Dually is built at the Saltillo Assembly Plant in Mexico.
