The new 2019 Ram 3500, 4500 and 5500 Chassis Cab will usher in a new generation of work trucks — one that leads the segment in capability, but also never-before-offered comfort and technology. Ram Chassis Cab trucks are the most durable, most capable and most confident cab and chassis trucks Ram has ever engineered. With a towing capacity up to 35,220 pounds, the highest Gross Combined Weight Rating of 43,000 pounds and payload up to 12,510 pounds, Ram's heaviest haulers are built for unforgiving duty cycles while achieving new levels of efficiency and upfitter friendliness.
While keeping true to the work truck mission, Ram Chassis Cab designers worked closely with engineering to give Ram's line of halo-capability trucks an optional level of comfort with the new Limited model for those customers who have an enthusiast's passion and want a fitting truck to handle the weight. The 2019 Ram Chassis Cab also offers a 12-inch reconfigurable touchscreen display with SiriusXM with 360L. Adding to its leadership in technology, the new 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, according to the manufacturer.
"Ram Chassis Cab operators work their trucks at maximum capability in the harshest drive cycles every day. By offering 35,220 pounds of towing capacity, 12,510 pounds of payload and a Gross Combined Weight Rating of 43,000 pounds, our 2019 Ram Chassis Cabs take segment leadership in areas most important to customers and upfitters alike," said Reid Bigland, Head of Ram Brand, FCA. "With the Chassis Cab Limited, we've also created something the segment has never seen, surrounding owners in premium materials and technology with the highest quality interiors, active safety systems, and of course, our award-winning Uconnect technology."
The standard engine in the 2019 Ram 3500/4500/5500 Chassis Cab is the proven and potent 6.4-litre 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-litre 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-litre 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-litre 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 efficient, smooth-shifting TorqueFlite 8HP75 eight-speed automatic is the standard transmission with the 6.4-litre 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-litre HEMI V-8, and optional on the Ram 3500 Chassis Cab with the 6.4-litre 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-litre 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.
