The 2025 Ram 2500 gains about 1,000 lbs. in maximum towing capacity over the previous model with the new Cummins engine. (Laramie trim shown.)
After the light-duty Ram 1500 was updated in 2024, the Ram Heavy Duty lineup gets its turn with added towing capabilities, quicker 0-to-60 times, and more tech for 2025.
The 2025 Ram 2500 and 3500 Heavy Duty models feature two engines — the standard 6.4-liter HEMI V-8 engine and a new 6.7-liter Cummins Turbo Diesel engine that produces 430 hp and 1,075 lb.-ft. of torque.
The new 8-Speed TorqueFlite HD Transmission replaces the 6-speed automatic transmission from 2024 models.
2025 Ram Heavy Duty: More Efficient Towing
With the new Cummins engine, the latest 2500 gains about 1,000 lbs. in maximum towing capacity over the previous model. Max towing for the 3500 stays about the same but has moved from the 4.10 axle ratio to a more efficient 3.42 axle ratio for better fuel efficiency without sacrificing performance.
The 2025 Ram 2500 shaves a full 1.1 seconds off its 0 to 60 time (6.9 seconds vs 8.0 seconds).
The new 6.7-liter Cummins Turbo Diesel engine upgrades to 430 hp and 1,075 lb.-ft. of torque.
2025 Ram Heavy Duty: Exterior, Interior Upgrades
On the outside, the 2025 Ram Heavy Duty hasn’t strayed too far from its roots, but a new grille and split-LED headlamps give it a more modern look.
Inside, the new Uconnect 5 infotainment system goes big with a new 14.5-inch driver’s screen, 10.25-inch passenger screen, and 12.3-inch digital instrument cluster.
The passenger screen offers an HDMI plug to connect a device that turns the touchscreen into a projected extension of the device that allows internet searches, music and app use through the Uconnect 5 system.
The layout is completed with a digital rearview mirror and a dual wireless phone charging pad. The dial shifter moves to the column to free up dash space.
The new Ram Heavy Duty models feature bigger screens and a shifter that has moved from a dial to the stalk.
