Fiat Chrysler Automobiles unveiled at the Chicago Auto Show the 2019 Ram 3500, 4500 and 5500 Chassis Cab work trucks, which leads the segment in capability with a segment-leading towing capacity up to 35,220 pounds, the highest Gross Combined Weight Rating of 43,000 pounds and payload up to 12,510 pounds.

The 2019 Ram Chassis Cab now features never-before-offered comfort and technology, including the class-exclusive 12-inch reconfigurable touchscreen display with SiriusXM featuring the new 360L system. 

The new generation of Ram Chassis Cab is the only truck in the segment to offer adaptive cruise control, Forward Collision Warning, Automatic Emergency Braking (AEB) and AEB with trailer brakes on all trim levels.

The standard engine in the 2019 Ram 3500/4500/5500 Chassis Cab is a 6.4-liter HEMI V-8 with up to 410 horsepower and 429 lb.-ft. of torque.

The Ram 3500 Chassis Cab now employs exclusive Fuel Saver Technology cylinder deactivation to increase fuel economy. When the engine is paired with the optional Aisin AS66RC six-speed automatic transmission with Power Take-Off (PTO), Fuel Saver Technology functions under light load while in stationary PTO mode to reduce fuel consumption.

In the Ram 4500 and 5500 Chassis Cab, the 6.4-liter HEMI V-8, paired with the Aisin AS66RC electronically controlled 6-speed automatic transmission with optional Power Take-Off (PTO) capability, delivers 370 horsepower and 429 lb.-ft. of torque.

In all Ram 3500/4500/5500 Chassis Cab applications, the 6.4-liter HEMI V-8 uses interactive Deceleration Fuel Shut-Off, which stops fuel flow to the cylinders when decelerating, to improve fuel economy.

A significantly revised Cummins 6.7-liter inline-six turbo diesel is optional on the 2019 Ram 3500/4500/5500 Chassis Cab. Paired with the Aisin AS69RC electronically controlled six-speed automatic transmission with optional PTO capability, the Cummins engine delivers 360 horsepower and the highest available torque in Class 4 and 5 at 800 lb.-ft.

Changes to the Cummins engine include a cylinder block made from compacted graphite iron. Using compacted graphite iron produces a block that is stronger and better able to dampen vibrations. Overall, the new Cummins Turbo Diesel weighs 60 pounds less than the previous-generation engine.

A new cast-iron cylinder head builds on the new block with changes that include new exhaust valves and springs, and new rocker arms driven by a hollow camshaft, contributing to the weight savings. Changes to the Cummins Turbo Diesel also include a new oil pump and water pump with lightweight-aluminum housing.

The 2019 Ram 3500/4500/5500 Chassis Cab offers customers a trio of automatic transmissions. The TorqueFlite 8HP75 eight-speed automatic is the standard transmission with the 6.4-liter HEMI V-8 in the 2019 Ram 3500 Chassis Cab. It's also the first time an eight-speed transmission is offered in the segment.

The electronically controlled Aisin AS66RC six-speed automatic is the standard transmission for 2019 Ram 4500/5500 Chassis Cabs equipped with the 6.4-liter HEMI V-8, and optional on the Ram 3500 Chassis Cab with the 6.4-liter HEMI V-8. This transmission offers the option of PTO capability on the left or right side.

New 2019 Ram 3500/4500/5500 Chassis Cab trucks equipped with the Cummins 6.7-liter Turbo Diesel use an Aisin AS69RC six-speed automatic transmission also featuring PTO capability on the left or right side in 4x2 configurations.

The fully electronically controlled Aisin AS69RC uses a new transmission controller with double the memory of the previous controller for faster, more precise shifts under all driving and loading conditions.

Ram offers two different dual alternator systems on the 2019 Ram Chassis Cab. Models equipped with the Cummins 6.7-liter diesel engine offer dual 220-amp alternators (best-in-class 440 amps). Trucks equipped with the 6.4-liter HEMI V-8 gas engine offer a first-and-only application of its kind by combining 220- and 160-amp units for 380-amps of total best-in-class output.

The new 2019 Ram Chassis Cab is the only truck in the segment to offer an array of active AND passive systems to assist the driver and passengers. In the cab chassis segment, only the 2019 Ram Chassis Cab features Adaptive Cruise Control, Forward Collision Warning, Automatic Emergency Braking (AEB) and AEB with trailer brakes available on all trim levels.

Class-exclusive ParkSense Park Assist system provides visual and audible indications and a class-exclusive 270-degree camera system with trailer reverse-guidance view gives greater field of vision. Ram Chassis Cab offers a class-exclusive cargo-view camera allowing owners to monitor the upfit and/or payload in the rear of the truck. The system also aids hookup with fifth-wheel and gooseneck hitches.

Additional safety and security systems are geared toward a truck that will spend most of its life at the maximum duty cycle. Many of the technologies are enhanced, making the 2019 Ram Chassis Cab the most technologically advanced in the segment. The new 2019 Chassis Cab also can monitor up to six tires on the truck plus trailer tire pressure monitoring for up to 12 trailer tires.

Four trim levels are offered on the 2019 Ram Chassis Cab: Tradesman, SLT, Laramie and the new Limited. 

Three head lamp variations are available delivering the best lighting in the segment. All three configurations offer up twice the lumen output when compared to previous lighting. 

On the premium set, an Adaptive Front Lighting System (AFS) pushes beams up to 15 degrees in the expected direction of vehicle travel. LED systems come with lifetime warranty for lower total cost of ownership.

All navigation, Wi-Fi, radio and SiriusXM 360L tasks are handled by a new shark fin antenna – making the new 2019 Ram Chassis Cab the first-in-segment without a mast antenna. The new antenna reduces wind noise, improves signal reception and simplifies select upfits.

The 2019 Ram Chassis Cab is built at the Saltillo Truck Assembly Plant in Coahuila. Availability is second quarter of 2019. Pricing will be announced at a later date.
