Ram 2500: Heavy-Duty Power, Towing Capacity & Complete Specs Guide
Whether you’re hauling a 20,000-pound trailer across state lines or tackling the toughest job site, the Ram 2500 delivers the muscle you need. This heavy-duty truck combines legendary Cummins diesel performance with a remarkably refined interior that makes the workday feel effortless. From its best-in-class torque to its available 50-gallon fuel tank for extended range, the Ram 2500 dominates the three-quarter-ton segment. Let’s explore why this truck remains the top choice for drivers who demand serious capability without sacrificing comfort.
Engine Options: Choosing Your Ram 2500 Powertrain
The heart of any heavy-duty truck lies under the hood, and the Ram 2500 offers two powerful engine choices to match your specific needs. Each engine provides distinct advantages for work, towing, or daily driving.
6.4L HEMI V8 Gas Engine: Proven Power
The standard 6.4L HEMI V8 delivers 405 horsepower and 429 lb-ft of torque. This engine pairs with the TorqueFlite HD eight-speed automatic transmission for smooth, responsive performance. The HEMI features Variable Valve Timing and the Multi-Displacement System, which deactivates cylinders during light load conditions to improve fuel efficiency.
High-Output 6.7L Cummins Turbo Diesel I6: Maximum Torque
For heavy towing, the available High-Output 6.7L Cummins Turbo Diesel I6 stands as one of the most impressive engines in the segment. It produces 430 horsepower and an astounding 1,075 lb-ft of torque—the most of any base diesel in its class. This engine features a new intake system, larger-diameter valves, a quicker-spooling turbocharger, and increased fuel pressure for enhanced performance.
Ram 2500 Towing Capacity: How Much Can It Pull?
Towing capacity ranks as the most critical specification for heavy-duty truck buyers. The Ram 2500 offers impressive numbers regardless of engine choice.
Maximum Towing Capacities:
The Ram 2500 achieves these ratings through a combination of robust frame construction, advanced cooling systems, and the TorqueFlite HD eight-speed transmission. The diesel towing capacity of 20,000 pounds makes the Ram 2500 a formidable choice for heavy trailers, equipment hauling, and commercial applications.
Payload Capacity: Hauling Heavy Loads
Beyond towing, payload capacity determines how much weight you can carry in the bed and cabin. The Ram 2500 delivers best-in-class gas payload numbers.
Maximum Payload Capacities:
- 6.4L HEMI V8: Up to 4,580 pounds (3,930 pounds on certain configurations)
- High-Output Cummins Diesel: Up to 3,600 pounds
The HEMI-powered Ram 2500 offers the highest payload capacity, making it the ideal choice for truck owners who frequently carry heavy materials in the bed. The diesel engine weighs more, which reduces available payload capacity but increases towing capability.
