ENGINEERING
For 2013, Ram Heavy Duty trucks feature new frames built with high-strength 50 KSI steel, including eight separate cross-members, hydroformed main rails and fully boxed rear rails for optimal strength and mass efficiency. Wider front frame rails (approximately one inch per side; two inches overall) enable front suspension springs to be positioned slightly outboard, an enabler for generating more positive roll stiffness. A new front suspension cross member is now a two-piece welded component between the front axle and oil pan.
Center frame rail sections are roll-formed, an efficient means for maintaining consistent strength in less complex longitudinal sections. In the rear portion of the new frame, the structure includes fully boxed rear rails and a factory-installed rear axle cross member with provisions for 5th wheel and gooseneck hitches. A new conventional trailer hitch system is upgraded to Class 5 with a 17,000-lb. load capability and 1,800 pounds of tongue weight for use with 2-inch or 2.5-inch receiver hitches.
Suspension
To handle the best-in-class towing and payload capability of the new Ram Heavy Duty, a new front and rear suspension system with advanced geometry builds upon the chassis improvements and greatly improves overall roll stiffness. An advanced three-link front suspension on the Ram 3500 is necessary for the vehicle's higher GVWR and for use with heavy front loads, including snow plows. Additionally, a newly designed Hotchkiss leaf spring rear suspension on the Ram 3500 offers improved ride and handling while delivering higher towing and payload capability.
Steering
The new premium reciprocating ball steering gear, redesigned steering knuckles, ball joints and more robust steering linkages deliver enhanced and precise on-center feel despite the vehicles higher towing and payload capacities.
Body
A number of body improvements have been made to enhance overall noise, vibration and harshness (NVH) and to align with the best-in-class capabilities of the 2013 Ram Heavy Duty. The new truck comes equipped with an updated engine, transmission and body mounts, including pioneering hydro-mounts at C-pillar positions for class-leading NVH characteristics despite the truck's aptitude for higher payloads and towing.
A new capless fuel filler on diesel applications is a space-saving initiative that enables side-by-side fuel and diesel exhaust fluid (DEF) port configuration. The result is more convenient fuel and DEF re-fill at pump stations.
The Ram 3500 features a factory-installed trailer tow connector in the truck bed, included with the optional 5th wheel or gooseneck tow prep package. New structural support is designed into the body to support the payload increase and improve durability performance. Additionally, new reinforced tie-down points with enhanced strength are designed for heavier loads.
Electrical
A majority of the commercial truck customers need to tie into the electrical system. A new best-in-class, vehicle system interface module (VSIM) is capable of communicating between aftermarket modules and various factory control modules. The VSIM up-fitter interface module features a total of 72 inputs and outputs, including lighting controls, door position and throttle and transmission position. The class exclusive module acts as a secure gateway to the vehicles' electrical system.
Additional new features
New for 2013, central locking includes the RamBox cargo management system and tailgate power locks, creating a convenient solution for locking all exterior doors and storage with one push of a button. Auto rain-sensing wipers and SmartBeam headlamps also find their way into the feature availability list of the new 2013 Ram Heavy Duty.
Total cost of ownership and unsurpassed powertrain warranty - 5 years/ 100,000 Miles
Operating costs are of great consideration for owners who use their trucks for work. The 2013 Ram Heavy Duty holds class-leading features in:
Fuel economy with introduction of a new DEF system
Extended maintenance cycle (oil change, fuel filter life)
Brake life with advanced engine exhaust brake and largest brakes in the segment
The 2013 Ram Heavy Duty is backed with an unsurpassed 5-year/100,000-mile Powertrain Limited Warranty. The powertrain-limited warranty covers the cost of all parts and labor needed to repair a covered powertrain component - engine, transmission and drive system. Coverage also includes free towing to the nearest Ram Truck dealer, if necessary. The warranty also is transferable allowing customers who sell their truck during the warranty period to pass the coverage onto the new owner. The standard 3-year/36,000-mile Basic Limited Warranty provides bumper-to-bumper coverage for the Ram Heavy Duty, from the body to the electrical system.
POWERTRAIN
For 2013, the 5.7-liter HEMI® V-8 makes its debut in Ram 3500 Heavy Duty pickup as standard equipment (single rear wheel). Also standard in the Ram 2500 Heavy Duty, the engine produces 383 horsepower at 5,600 rpm and generates peak torque of 400 lb.-ft. at 3,950 rpm. The HEMI V-8 is mated to a 66RFE six-speed automatic transmission.
Dominating the power charts, the renowned 6.7-liter Cummins High-Output Turbo Diesel I-6 is now available in three versions. The first version is paired with Ram's segment exclusive six-speed manual transmission, which features a wear-compensating clutch for lifetime "like-new" performance and a dual-trunion shift tower to accommodate a compact shift pattern. This combination delivers 350 horsepower at 2,800 rpm and 660 lb.-ft. of torque at 1,500 rpm - a significant boost from the 2012 model-year maximum of 600 lb.-ft.
The second option matches the Cummins to the 68RFE six-speed automatic transmission. The diesel engine cranks out 370 horsepower at 2,800 rpm with an unsurpassed in ¾-ton trucks 800 lb.-ft. of torque at 1,600 rpm.
For 2013, all Ram Heavy Duty diesels benefit from an all-new cooling system. A high-efficiency fan, dual radiators, dual transmission coolers and charge air cooler afford 25 percent more heat-rejection capacity. Lower operating temperatures deliver improved performance, durability and lower operating costs.
Diesel-equipped Ram Heavy Duty pickups feature an industry-exclusive Ram Active Air intake system, activated by new monitoring capabilities added to the engine controller. When the intake system senses extreme heat, it draws cool air from the front of the vehicle - a function that also engages at high altitudes for superior throttle response in low oxygen environments. When conditions are wet from snow, ice or water-fording, the system pulls air from an underhood inlet clear from snow packing and water ingestion.
The list of 2013 diesel-engine features does not end there. The Cummins powerplants benefit from a larger exhaust-gas recirculation (EGR) cooler, which complements the debut of selective catalytic reduction (SCR) and accommodates a best-in-class oil-change interval of 15,000 miles. Oil life is increased by reducing soot production and reducing fuel dilution of the oil.
Combined with a 10 percent improvement in fuel economy due in part to the engines' high-pressure common-rail fuel system, SCR promises a net reduction in Ram Heavy Duty operating costs. The SCR-equipped diesels, which can run on B-20 biofuel, also operate cleaner by lowering greenhouse-gas emissions and better managing soot production than Lean NOx Trap (LNT) technology.From behind the wheel, the diesels deliver improved cold-start performance and superior refinement from innovations such as the new smart exhaust brake system. Enabled by Cummins' unique, proprietary sliding-nozzle turbine design, the feature electronically manages best-in-class exhaust braking for smoother downhill driving, regardless of vehicle load.
Cummins' variable-geometry turbocharger also affords more effortless operation at higher altitudes, greater management of EGR flow rates and improved control over exhaust temperatures to accommodate de-sooting.
For the 2013 Ram Heavy Duty, no detail was too small to consider - an approach that inspired the design of a new fuel filter/water separator. The frame-mounted unit delivers best-in-class, 3 micron particulate filtration and water stripping for improved engine performance and durability.
Capability is high on the priority list for Ram engineers, evidenced by axle upgrades for 2013.
The 2013 Ram 3500 boasts a best-in-class GCWR. A contributor is the 11.8-inch rear axle matched with the diesel engine boasting a 300-mm hypoid gear set, a 4-pinion helical differential and an aluminum ring-gear cover for optimal cooling - and improved aesthetics.
The Ram Heavy Duty also features a segment-exclusive front axle disconnecting system. When conditions warrant, select drivetrain components are disconnected, improving overall efficiency and enabling a gain in fuel efficiency of up to 1 mpg.
