January 7, 2025 , Auburn Hills, Mich. – Today, Ram unveiled the new 2025 Ram Chassis Cab trucks, featuring a new 6.7-liter Cummins Turbo Diesel engine with power take-off (PTO) capability for left- and right-side operation. Ram’s heaviest haulers relentlessly give maximum effort with a unique combination of upfitter-friendly innovation, durability and capability.

“The Ram Chassis Cab line represents our hardest working trucks — designed and engineered to run at maximum capability all day, every day,” says Ram Brand CEO Tim Kuniskis. “In this segment, durability, low cost of ownership and innovative upfitter solutions are top of mind for our customers and our engineering and planning teams.”

Powertrain
The 2025 Ram Chassis Cab offers customers two engine options — the new 6.7-liter Cummins Turbo Diesel engine and the standard 6.4-liter HEMI® V-8 engine. A new electronic column shifter and TorqueFlite HD eight-speed automatic transmission are standard equipment on both engines.

The all-new 6.7-liter Turbo Diesel engine is rated at 360 horsepower and 800 lb.-ft. of torque, while the 6.4-liter HEMI V-8 is rated at 375 horsepower and 429 lb.-ft. of torque.

Working closely with Cummins, the 6.7-liter inline-6-cylinder Turbo Diesel engine boasts several improvements in drivability, fuel economy, durability, startability, serviceability and noise, vibration and harshness (NVH).

A redesigned block and head, robust heavy-duty pistons, new performance intake manifold, a new turbo, larger intake/exhaust valves for improved port flow and a higher-pressure fuel system enhance the diesel’s hallmark durability and efficiency.

To make service easier, and improve air flow and performance, the new Cummins engine utilizes improved intake port geometry for top feed injectors, top load lubrication and integrated fuel filters. Helping customers in extremely cold environments, Ram Chassis Cab trucks equipped with the Cummins Turbo Diesel utilize glow plugs. Additionally, noise, vibration and harshness were improved using helical transmission gears.

Also new for 2025, the selectable oil change interval allows customers to elect B20 biodiesel for notification on proper oil change timing:

B20 biodiesel oil change interval – 12,000 miles
Regular diesel oil change interval – 15,000 miles

The new 2025 Ram Chassis Cab trucks integrate the TorqueFlite HD eight-speed automatic transmission that features a lower cruise engine rpm and improved performance on graded roads.

Wide gear ratios allow for a reduction in rear axle ratio without compromising capability. The TorqueFlite HD eight-speed automatic transmission and new electronic column shifter are now standard on both engine options.

Capability includes a maximum towing capacity of 34,540 pounds (5500) and a maximum payload of 11,960 pounds (5500).

For 2025, Ram Chassis Cab trucks feature updated grilles with a unique design, depending on the selected trim level. New premium LED headlamps, including twin bi-functional projectors, are available, while LEDs are now standard.

Upfitter Friendly
Ram’s heaviest haulers are built for unforgiving duty cycles while achieving new levels of efficiency and upfitter friendliness. They are classified as medium-duty vehicles and offer higher payload and towing ratings than Class 2-3 heavy duty pickups.

Chassis Cab trucks are sold without a conventional pickup bed but include a third-party manufactured and installed vocation-specific upfit prior to customer delivery. Customers benefit from Ram’s relationships with body manufacturers and upfitters contributing to the most upfitter friendly Ram Chassis Cab ever.

Industry standard cab-to-axle lengths of 60, 84, 108 and 120 inches
No components or lines above the rear frame rails
Through-the-frame plumbing and electrical
Diesel exhaust fluid (DEF) tank refill port located at the rear of the cab on the driver’s side
New for 2025, power take-off (PTO) capability for left- and right-side operation

All Ram Chassis Cab trucks equipped with the Cummins Turbo Diesel option come standard with power take-off (PTO) capability with improved use parameters for left- and right-side components and a dedicated switch. It works in more situations to provide minimum split-shaft PTO horsepower while stationary through a remote throttle. The new offering also provides protection to engine and PTO equipment with fail-safe by allowing aerial lifts to be lowered without engine power.

An on-board power inverter offers up to 2.4 kilowatts with relocatable point of service for ease of upfit. With the engine running and while the truck is in park, customers can turn the inverter on via the touchscreen and with a switch located to the left of the outlets. The engine will then ramp up revolutions per minute (rpm) to support the on-board power inverter.

A best-in-class vehicle system interface module (VSIM) can communicate between aftermarket modules and various factory control modules. The VSIM features more than 70 inputs and outputs, including lighting controls, door position, and throttle and transmission position.

Details are important when installing an upfit. Ram created a digital rearview mirror (DRVM) relocation kit featuring connection points for adding a camera that replaces the DRVM camera that could be blocked by an upfit. The new 2025 Ram Chassis Cab also features a standard upfitter electrical connector and an integrated cab configuration for easy upfitter/conversion solutions.

It also reverts to a traditional reflective mirror by toggling the switch underneath.

Telescoping trailer tow mirrors allow the driver to move the mirrors away from the truck to enhance sightlines while towing.

Trailer-Tow Pages gives customers the ability to view comprehensive trailer monitoring information including Trailer Light Check-out, Trailer Brake Status and auxiliary camera shortcuts, all in one application accessible through the Uconnect touchscreen.
