ENGINEERING

For 2014, Ram engineers have enhanced the 3500 Chassis Cab model with a new three-link front suspension that provides greater load-carrying capability and best-in-class towing.

Ram 4500 and 5500 Chassis Cabs have received upgrades as well. Both models are now rated for up to 7,000 pounds of front Gross Axle Weight Rating (GAWR) on 6.4-liter gas engine-equipped models and up to 7,250 pounds GAWR on 6.7-liter Cummins Turbo Diesel models.

Gross Vehicle Weight Ratings (GVWR) for Ram 3500 models equipped with single rear wheels have been raised, now ranging from 10,500 to 12,000 pounds. A 10,000-lb. GVWR model that falls below certain truck-weight restrictions is also available.

To handle the best-in-class towing and unsurpassed GVWR capability of the Ram Chassis Cab, robust front suspension springs handle heavier loads while maintaining front ride height and improving overall roll stiffness. Greater roll stiffness, also known as body roll, is an important characteristic in taller vehicles, especially trucks with heavy payloads. An advanced five-link front suspension on Class 4 and 5 Ram 4500 and 5500 Chassis Cab trucks ensures excellent ride and handling for a higher GVWR and for use with heavy front loads, including snow plows. The Hotchkiss rear leaf spring suspension not only provides a minimum of zero degrees rake angle at max load, it also maintains objectives for ride and handling.

With upfits in mind, the 2014 Ram Chassis Cab trucks feature frames built with high-strength 50,000 psi steel, including eight separate cross-member construction. Designing the frames for upfits creates a competitive advantage, improves durability and reduces warranty costs from unapproved modifications. Ram Chassis Cab trucks have no components or lines above the rear frame rails. For example, the diesel exhaust fluid tank (DEF) is located under the cab and out of the upfit zones. The feature reduces the need for modification and relocation that is sometimes required in competitive trucks. One piece, C-channel rear frame rails, and through-the-frame plumbing and electrical provide a flat plane for ease of mounting application bodies and accessories.

Steering

The drag link is positioned over the track bar to reduce roll oversteer and to improve tracking at highway speeds. Also, the drag link is attached directly to the knuckle, offering improved efficiency for driver input. The caster and track are engineered for more wheel-aligning torque, which improves return-to-center at the steering wheel. A ball joint alignment feature and sealing method improves alignment and service for lower total cost of ownership. This design results in enhanced and precise on-center feel, despite the vehicle’s impressive towing and payload capacities.

Body

The 2014 Ram Chassis Cab comes equipped with engine, transmission and body mounts for class-leading noise, vibration and harshness (NVH) characteristics.

Ram 3500, 4500 and 5500 Chassis Cab commercial trucks are available with an engineering-approved, upfitter-friendly solution for customers who require back panel removal on regular cab trucks. Because the instructions were created and approved by Ram Commercial truck engineers, the cutaway design retains the structural integrity of the truck.

Electrical

As the Ram Chassis Cab continues to offer more featured content, it created the need for a technology that allows more information to be electronically communicated within the truck. The Powernet system allows both high- and low-speed data networks to be equipped with as many as 40 individual modules, all designed to improve vehicle performance and enhance the comfort and safety of driver and passengers.

A majority of the commercial truck customers need to tie into the electrical system, and certain fleet customers require access to vehicle information. A best-in-class VSIM is capable of communicating between aftermarket modules and various Chassis Cab control modules. The class-exclusive module acts as a secure gateway to the vehicle’s electrical systems and data bus architecture to enable safe, secure plug-and-play connectivity for up-fitter use.

An optional dual 220-amp alternator system (440 amps total) on the diesel-equipped Ram Chassis Cab provides best-in-class electrical capability for the higher electrical loads required in select upfits such as emergency lighting and electric clutch pumps. The new 6.4-liter gas powertrain gets a dual-alternator option, pairing a 220-amp unit with a 160-amp, for a total of 380 amps.

A segment exclusive selective tire pressure display is standard for both single- and dual-rear-wheel 3500 models.

Total cost of ownership and unsurpassed powertrain warranty - five years/100,000 miles

Operating costs are of great consideration for owners who use their trucks for work. The 2014 Ram Chassis Cab claims class-leading features in:

Extended maintenance cycle (15,000-mile oil change, fuel filter life)

Brake life with advanced engine exhaust brake

Upfit integration

The 2014 Ram Chassis Cab is backed with a unsurpassed, five-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 is transferable allowing customers who sell their truck during the warranty period to pass the coverage on to the new owner. The standard three-year/36,000-mile Basic Limited Warranty provides bumper-to-bumper coverage for the Ram Chassis Cab, from the body to the electrical system.

POWERTRAIN

The 2014 Ram Chassis Cab 3500, 4500 and 5500 come standard with the new 6.4-HEMI® V-8 gasoline engine — the first implementation of a gasoline engine for the Ram 4500 and 5500 Chassis Cab models. The Chassis Cab version of the 6.4 HEMI is similar by design but is engineered for a different duty cycle, when compared to the version offered in the Ram 2500 and 3500. The all-new powerplant provides a worthy gas-powered option to the segment’s overall standard-bearer – the 6.7-liter Cummins Turbo Diesel.

Compelling numbers tell the story of the new 16-valve engine: estimated up to 410 horsepower (302 kW) at 4,600 rpm (4,600 rpm for Aisin in 4500/5500) and a peak torque rating of 429 lb.-ft. (582 N•m) at 4,000 rpm. Ram’s new 6.4-liter V-8 gasoline engine is the first of its kind for Class 4 and 5 Ram 4500 and 5500 Chassis Cab trucks.

The new, big gasoline engine offers a number of features important to the hard, working, heavy- and medium-duty segments, including the dual-alternator option and a programmable idle shut-down timer. Additionally, the engine features Fuel Saver cylinder deactivation operation under normal driving conditions (66RFE transmission) and during PTO mode (Aisin transmissions) to improve efficiency.

The new 6.4-liter HEMI is available with the 66RFE six-speed automatic transmission or the AS66RC six-speed automatic transmission with segment exclusive, gasoline engine left- or right-side PTO capability.

The 3500 Chassis Cab also is available with the legendary 5.7-liter HEMI V-8 gasoline engine. The engine produces 383 horsepower at 5,600 rpm and generates peak torque of 400 lb.-ft. of torque at 4,000 rpm. Mated to the 66RFE six-speed automatic transmission, the HEMI features enhanced fuel efficiency and power output, thanks to the incorporation of variable-valve timing (VVT) and a compression ratio of 9.6:1. Refinements and other applied technologies provide the latest-generation HEMI with performance and fuel economy improvements to rival multi-valve V-8 offerings.

Unlike the competition, Ram offers two engine variants based on the 6.7-liter Cummins for diesel supremacy in the segment.

The first version features 320 horsepower at 2,800 rpm and 650 lb.-ft. of torque at 1,400 rpm. The engine is paired with Ram’s segment-exclusive six-speed manual transmission, which features a wear-compensating clutch for consistent performance and a dual-trunion shift tower to accommodate a compact shift pattern.

A second high-output diesel delivers 325 horsepower at 2,400 rpm and generates best-in-class torque of 750 lb.-ft. at 1,600 rpm. The engine is paired with an Aisin six-speed automatic transmission (AS69RC).

The Aisin AS69RC transmission features robust components and impressive shift performance, transmission efficiency and drivability when compared to the competition. The transmission is designed for high engine ratings and enables a left- and right-side PTO option, as well as allowing for a split shaft PTO configuration (diesel). Fire pumpers, dump beds, aerial buckets, cranes and onboard compressor/generators are typical PTO based upfits.

New for 2014, Ram 3500 Chassis Cab trucks are equipped with a front-axle disconnect for greater fuel efficiency.

All Ram Chassis Cab diesels benefit from an advanced cooling system. A high-efficiency fan, dual radiators, dual transmission coolers and charge air cooler provide impressive heat-rejection capacity to align with best-in-class GCWR. Lower operating temperatures deliver unsurpassed performance, durability and lower operating costs.

Best-in-class GCWRs also facilitated by the industry-exclusive Ram Active Air intake system, activated by monitoring capabilities in the engine controller. When the exclusive intake system senses extreme heat, it draws cooler 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 under- hood inlet, clear from snow packing and water ingestion.

A new, dual fuel tank option combines 52-gallon and 22-gallon tanks for 74 gallons of extended, integrated onboard fuel range for lower operating costs. Additionally, a mid-ship 22-gallon tank is now an option for gasoline- and diesel-powered Chassis Cabs.

Emissions performance

The Cummins power plants utilize a large exhaust-gas recirculation cooler, which complements the selective catalytic reduction (SCR) and accommodates a best-in-class oil-change interval of 15,000 miles. Oil life is longer by reducing soot production and reducing fuel dilution of the oil.

When needed, the diesel exhaust fluid (DEF) is injected into the exhaust to reduce NOx (Nitrogen Oxides) emissions coming out of the tail pipe. Unlike the competition, the Ram Chassis Cab maintains full power when fluid is low. The state-of-the art DEF system applied on the Ram Chassis Cab features an electric heater in the DEF tank to ensure the fluid is available in a liquid state regardless of climate. The DEF refill port is conveniently located at the rear of the cab on the driver’s side of the vehicle, and clear of upfit zones, a configuration that ensures easy access at fuel stations when compared to the competition.

Combined with an improvement in fuel economy, due in part to the engines’ high-pressure common-rail fuel system, SCR provides a net reduction in Ram Chassis Cab operating costs.

The SCR-equipped Cummins engines also operate cleaner by lowering greenhouse-gas emissions and better managing soot production than Lean NOx Trap (LNT) technology.
