What’s New With the Commercial Ram Chassis Cab for 2019?

Long the third place finisher behind commercial trucks from Ford and General Motors, the new 2019 Ram Heavy Duty and Ram Chassis Cab line makes massive improvements upon the outgoing model in all of the areas that count, leaving many to wonder whether this isn’t the new leader in the full-size truck segment. While the new Ram Heavy Duty is still unlikely to outsell the Ford Super Duty or the Chevrolet Silverado HD, it’s still worth strong consideration, as the new Ram Heavy Duty line is a winner all around. Here, we’ll take a look at some of the most notable features of the new Ram Chassis Cab.


The Ram Chassis Cab’s standard engine is a 6.4-liter HEMI V8 that puts out 410 horsepower and 429 lb-ft of torque in 3500 models and 370 hp and 429 lb-ft in the 4500 and 5500. With the gas engine, the 3500 comes standard with a new 8-speed automatic, while the 4500 and 5500 offer a 6-speed automatic that offers a power take off for use with a snow plow or other accessories. The 6-speed auto is optional on the 3500.

An inline 6-cylinder Cummins turbo-diesel is optional, and puts out 360 hp and 800 lb-ft of torque. Slightly modified over the iteration found in the outgoing model, the updated diesel features a new cylinder block, new cylinder heads, new rocker arms, and new oil and water pumps. Paired with the diesel is a 6-speed automatic.

The 6-speed automatic comes with power take off capability from either its left or right side. Six-speed chassis cabs still come with an old-school column shifter, while 8-speed-equipped Chassis Cabs come with a rotary dial gear selector.


3500, 4500 and 5500 versions of the Chassis Cab are available, covering GVWR classes 3, 4, and 5. A Class 2 version is also available, offering a gross vehicle weight rating of 10,000lbs.

Buyers can choose between Single and Crew Cab designs.

The 2019 Ram Chassis Cab is available in four different trim levels; Tradesman, SLT, Laramie and Limited. That the Chassis Cab is available in Limited trim is noteworthy, as it means Ram is the only manufacturer to offer its chassis cab models in its top-of-the-line pickup trim. Buyers looking for a luxury dump truck should take note.


As the Chassis Cab is available in the rest of the Ram truck lineup’s luxurious Limited trim, the Chassis cab offers a variety of luxury features not offered by the competition. Buyers can choose from 5.0-, 8.4- and 12.0-in center infotainment screens, either a 3.5- or 7.5-in gauge cluster screen, and a Harmon Kardon 17-speaker audio system. Navigation and a Wi-Fi hot spot system are also available.


Ram’s Chassis Cab is available with a variety of great active safety features. Forward-collision warning, automatic emergency braking with trailer brake integration, adaptive cruise control, front and rear parking sensors and a rear-view camera system with trailer assistance are optional on all trim levels — from Limited down to Tradesman. A trailer tire pressure monitoring system is available as well.


Altogether, the new Ram Chassis Cab offers respectable performance via an available HEMI V8 or Cummins turbodiesel, the latter of which puts out a respectable 800 lb-ft of torque. As the new Ram pickup line is generally regarded as offering the best interior in the segment, buyers looking for a little extra refinement will find much to enjoy about the Ram Chassis Cab, especially given that it can be had in the Ram pickup’s top-of-the line Limited trim. Find a Ram 3500 for sale or Find a Ram 4500 for sale or Find a Ram 5500 for sale
