Ram has unveiled its 2019 chassis cab models, saying the lineup will boast segment-leading towing capacity and Gross Combined Weight Rating.

The 2019 Ram 3500, 4500 and 5500 chassis cab trucks, which share exterior design elements with the recently unveiled 2019 Ram HD trucks, will be offered in four trim levels: Tradesman, SLT, Laramie and Limited.

They will be available with a 6.4-liter HEMI V8 or a 6.7L inline-six Cummins turbo diesel. Paired with the TorqueFlite 8HP75 eight-speed automatic on the 3500, and the Aisin AS66RC 6-speed transmission on the 4500 and 5500, the HEMI delivers 410 horsepower and 429 lb.ft. of torque.

The Cummins, which Ram says is 60 pounds lighter and is made from a stronger compacted graphite iron block that dampens vibrations, has 360 horsepower and a 800 lb.ft. of torque—the most available toque in Classes 4 and 5—and is paired to the Aisin AS69RC six-speed.

As an available option, the HEMI can also be paired with the AS69RC. Power Take-Off is an available option on both Aisin transmissions, on the left or right side with the AS66RC, and on the left or right side in 4×2 configurations on the AS69RC.

The trucks boast 35,220 pounds of towing capacity, a 43,000-pound GCWR and a payload of 12,510 pounds.

The four-wheel disc braking system on these trucks have been upgraded to deliver more confident braking with less driver effort, Ram says, and also has a larger ratio pedal swing. Stopping distances have decreased as well.

Available in four, cab-to-rear-axle frame lengths (60, 84, 108 and 120 inches), the frames of these trucks are 97 percent high-strength steel and feature eight separate cross members. For upfitters, the rear frame sections feature a C-channel design with a flat mounting surface. The design offers “zero component interference above the rails, making upfit and accessory design/installation easy, cost-effective and reliable. Additionally, pre-drilled holes are designed throughout the structure to route upfit lines or mount hardware related to the upfit,” according to Ram’s press materials.
