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 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.
