2025 RAM 2500: Engines, Configurations, and How to Spec One

The RAM 2500 is the three-quarter-ton truck for work a half-ton can’t take on — heavy trailers, real payload, and the kind of daily use that wears out a lighter truck early.

Getting the configuration right matters more here than almost anywhere else. Here’s how the 2025 lineup breaks down.

The Engines

The 6.4L HEMI V8 costs less up front and per service interval, with no emissions-system complexity. If your towing is heavy but occasional, it’s often the smarter financial choice — and gas engines generally deliver higher payload ratings, since the diesel itself weighs more.

The 6.7L Cummins is why most people buy a 2500. Ten seventy-five lb-ft of torque launches a loaded gooseneck and holds grade without drama, and the exhaust brake matters as much as the power on the way back down.

New for 2025: diesel models get an eight-speed automatic, replacing the previous six-speed. Smoother shifts, better gear spacing, and improved towing behavior. If you’ve driven an older Cummins truck, this is a noticeable change.

Towing and Payload

Up to 20,000 pounds of towing and roughly 3,150 pounds of payload, depending on configuration.

Those figures belong to specific builds. Engine, cab, bed, axle ratio, and drivetrain all move them, and options eat into payload.

Bring us three numbers — your trailer’s loaded weight, its pin or tongue weight, and the payload you’ll carry in the bed. We’ll check them against the door-jamb sticker on specific trucks. That conversation takes ten minutes and prevents the most expensive mistake in this segment.

Cab Configurations

Regular Cab, Crew Cab, and Mega Cab.

The Mega Cab deserves specific mention: substantially more rear-seat room than a Crew Cab, with reclining rear seats. If your crew rides with you daily, or if you spend long days in the truck, it’s the one to look at. The trade is bed length.

Power Wagon and Rebel

Two off-road-oriented trims, and they’re not interchangeable.

Power Wagon — the serious one, and the only three-quarter-ton with a factory-installed winch. It also brings front and rear locking differentials, an electronic disconnecting front sway bar for articulation, Bilstein shocks, and skid plates.

One important constraint: the Power Wagon comes with the 6.4L HEMI V8 only. You can’t order one with the Cummins. If you need diesel torque and off-road hardware in the same truck, that’s a conversation worth having before you fall for a specific configuration.

Rebel — off-road styling and capability upgrades with broader powertrain availability.

Exterior

An aggressive grille and fascia with LED adaptive headlights that pivot to illuminate through turns — genuinely useful on unlit desert roads.

Available RamBox Cargo Management System with lockable, drainable bed-side bins. Tools stay secure and out of the weather, and the drains mean they double as coolers.

Power-deployable running boards, a dampened tailgate, and LED lighting throughout the bed and hitch area so you’re not working by phone light when you’re hooking up after dark.

Interior

The 2500 spans work truck to genuinely luxurious.

Up to a 14-inch touchscreen, wireless phone charging, remote start, and memory settings for the driver’s seat and mirrors.

Premium materials on higher trims including leather-trimmed seating, real wood accents, and soft-touch surfaces.

Heated and ventilated front seats, dual-zone climate control, and a heated steering wheel. On a ten-hour tow day, none of those are luxuries.

Storage including a large center console, rear in-floor bins, and fold-flat rear seats.

Safety and Driver Assistance

• Adaptive Cruise Control with Stop
• Automatic Emergency Braking
• Lane Keep Assist
• 360-degree surround-view camera and trailer reverse guidance — the combination that makes backing a long trailer manageable
• Blind-spot monitoring with rear cross-path detection
• Drowsy driver alerts and traffic sign recognition
• High-strength steel frame, multistage airbags, and side-impact beams

Is the 2500 the Right Truck?

If you tow above roughly 20,000 pounds or need maximum payload, step up to the RAM 3500, which offers dual-rear-wheel configurations.

If you tow under about 12,000 pounds and don’t carry heavy payload, a RAM 1500 will do the job for less money, better fuel economy, and a much easier daily drive.

The 2500 sits between them, and for a lot of buyers around El Paso and Las Cruces, it’s exactly the right amount of truck.

Frequently Asked Questions

What engines does the 2025 RAM 2500 offer? A standard 6.4L HEMI V8 producing 405 horsepower and 429 lb-ft of torque, and an available 6.7L Cummins Turbo Diesel inline-six producing up to 430 horsepower and 1,075 lb-ft.

How much can the 2025 RAM 2500 tow? Up to 20,000 pounds depending on configuration, with payload around 3,150 pounds. Check the door-jamb sticker on the specific truck before matching it to a trailer.

Do diesel RAM 2500 models have a new transmission for 2025? Yes. Diesel models moved to an eight-speed automatic, replacing the previous six-speed, for smoother shifts and improved towing behavior.

Can you get a RAM 2500 Power Wagon with the Cummins diesel? No. The Power Wagon comes with the 6.4L HEMI V8 only.

What makes the Power Wagon different? A factory-installed winch, front and rear locking differentials, an electronic disconnecting front sway bar, Bilstein shocks, and skid plates. It’s the only three-quarter-ton pickup that comes with a winch from the factory.

What cab styles does the RAM 2500 offer? Regular Cab, Crew Cab, and Mega Cab. The Mega Cab offers substantially more rear-seat room with reclining rear seats, trading bed length for it.

Should I get gas or diesel in a RAM 2500? It depends on how often you tow heavy. The Cummins costs more up front and per service and pays it back through capability, fuel economy under load, and resale. If you tow near capacity most weeks, diesel makes sense. If you tow heavy occasionally, the 6.4L HEMI is usually the better financial choice and offers higher payload.
