Detailed item info Model OverviewRam's powerful 2500 and 3500 Heavy-Duty (HD) trucks return for 2014 with even more to like. Across the HD range. there's now a choice between gasoline engines in the standard 5. 7L Hemi V8 and a new 6. 4L Hemi V8. while three versions of the 6. 7L Cummins inline 6-cylinder diesel top the range. All engines include a 6-speed automatic transmission. although a 6-speed manual transmission is offered with the diesel engine. The 5. 7L Hemi is rated at 383 horsepower and 400 ft-lb of torque. The new 6. 4L Hemi V8 makes 410 horsepower and 429 pound-feet of torque. With the 6-speed manual. the Cummins is rated at 350 horsepower and 660 pound-feet of torque at just 1. 00 rpm. When mated to the 6-speed automatic transmission. output jumps to 370 hp and 800 lb-ft. In Ram 3500 trucks with the top-duty Aisin automatic. it makes 385 hp and a staggering 850 lb-ft. High-pressure common-rail fuel injection helps aid refinement and clean up emissions and the Cummins is B20 biodiesel-blend compatible. Diesel Rams employ a Ram Active Air intake system that draws more cool air from the front of the truck for more power in hot temperatures or at high altitude. Also thanks to a variable-geometry turbocharger. Ram HD trucks have good responsiveness and drivability no matter what the load. Ram HDs can be ordered with either rear-wheel drive or 4-wheel drive. In 4-wheel-drive models. a front-axle disconnect system can help improve fuel economy by up to 1 mpg. The Ram 3500 utilizes a Hotchkiss leaf-spring rear suspension. while 2500s have replaced leaf springs with a 5-link coil spring setup. Front suspension is now courtesy of a 3-link system. 2500s can be optioned with heavy-duty air suspension in place of the coil springs. which allow for driver-controlled load leveling with precise. individual adjustment. Leaf-sprung 3500 dually trucks with maximum tow packages also feature the air suspension system in conjunction with the rear leaf springs. Ram 2500 trucks benefit from a larger rear axle. 11. 5 inches for 2014. while the high-output Cummins includes an 11. 8-inch axle. The result is best-in-class towing and payload ratings for the 3500 (up to 30. 00 lb and 7. 20 lb. respectively). and best-in-class towing for the 2500 -- up to 17. 40 lb. For the first time. Ram offers an optional fifth-wheel tow package. Ram understands that its trucks must last a lifetime. As a start. the company offers a 5-year. 100. 00-mile warranty on all of its powertrains. Each truck also has extended maintenance cycles for fuel filters and oil changes. including a 15. 00-mile interval on the Cummins diesel. Inside.
