2025 Ram Heavy Duty: What to Expect
The 2025 Ram Heavy Duty (HD) trucks continue the tradition of offering extensive customization options. Buyers can choose from various cab sizes, bed lengths, trim levels, and powertrains to fit their specific needs. This overview details the engine choices, cab configurations, and features available across the HD lineup.
Engine Options and Powertrain
The 2025 Ram HD offers two engine choices: a gasoline-powered V8 and a reworked Cummins turbo-diesel.
- Standard Engine: The standard engine is a 6.4-liter Hemi V-8, producing 405 horsepower and 429 pound-feet of torque.
- Available Diesel Engine: The available 6.7-liter inline-six Cummins turbo-diesel receives significant updates for the 2025 model year. These updates include a revised block, head, and a new turbocharger. Importantly, all diesel options are the high-output version, rated at 430 horsepower and a substantial 1,075 pound-feet of torque. The diesel engine is now exclusively paired with an eight-speed automatic transmission, replacing the previous six-speed option.
Rear-wheel drive (RWD) is standard on most models, with four-wheel drive (4WD) available. However, the 2500 Power Wagon and Rebel models come standard with 4WD.
Configuration Options
The Ram HD is available in a dizzying array of configurations, including:
- Cab Sizes: Regular (two-door), Crew Cab and Mega Cab.
- Bed Lengths: 6-foot-4-inch and 8-foot beds.
- Dually: Dual rear wheels are available on the 3500 models, but only with the 8-foot bed.
- Trim Levels: Tradesman, Big Horn, Power Wagon, Rebel, Laramie, Limited, and Limited Longhorn. (Five levels on the 3500).
The regular cab with an 8-foot bed is exclusive to the Tradesman and Big Horn trims. The crew cab with a 6-foot-4-inch bed is standard for most of the lineup. The crew cab with the 8-foot bed is available on all trims except the Power Wagon and Rebel. The Mega Cab option, which offers extended rear-seat legroom, is found on the Laramie, Limited, and Limited Longhorn trims. It is only available with the shorter bed, 4WD, and the diesel engine.
Safety and Technology Features
Standard safety features for the 2025 Ram HD include forward collision warning with pedestrian detection, automatic emergency braking, adaptive cruise control, and an integrated trailer brake controller. Available safety equipment includes lane departure warning, lane departure steering assist, a 360-degree camera system, road-sign recognition, a driver attention monitor, automatic high beams, and trailer tire-pressure monitors.

Each trim level offers a unique blend of features and styling:
