The 2021 Ram 2500 is a heavy-duty truck designed for serious towing, offering a maximum towing capacity of up to 20,000 pounds when properly equipped.

Quick answer

• Max Tow Capacity: Up to 20,000 lbs (conventional), up to 19,680 lbs (5th-wheel/gooseneck)
• Max Payload: Up to 4,010 lbs
• GVWR: 10,000 lbs (varies by configuration)
• GCWR: Up to 27,500 lbs
• Curb Weight: 6,056 lbs – 7,490 lbs (varies by configuration)
• Hitch Class: Class V (Integrated into bumper structure on some models, often available with both 2-inch and 2.5-inch receivers)

Tow ratings by engine & trim

The 2021 Ram 2500 offers two powerful engine options, each providing impressive towing capabilities. The ratings below represent the maximum capacities and can vary based on specific trim, drivetrain, cab configuration, bed length, and optional equipment. Always refer to your vehicle's door jamb sticker for precise figures.

Note: The Power Wagon model, while off-road focused, has a lower conventional towing capacity due to its specialized suspension and equipment, typically around 10,500 lbs, and does not support 5th-wheel/gooseneck towing.

Tow package contents

Ram understands the needs of serious towers and offers comprehensive towing packages to enhance safety and capability. While specific contents can vary by trim and package, common features include:

• Trailer Tow Group: Often includes features like a Class V receiver hitch and a 4-pin/7-pin wiring harness.
• Integrated Trailer Brake Controller: Allows for in-cab control of trailer brakes, providing smoother and more controlled stopping. This is a highly recommended feature for any trailer with electric brakes.
• Trailer Sway Control (TSC): An electronic stability control system designed to detect and mitigate trailer sway, helping drivers maintain control in adverse conditions.
• Auxiliary Transmission Oil Cooler: Helps maintain optimal transmission fluid temperatures during heavy towing, extending transmission life.
• Trailer Light Check: A feature that allows you to easily check all trailer lights from inside the cab.
• Trailer Tire Pressure Monitoring System (TPMS): An available system that monitors the air pressure in your trailer's tires and displays it in the vehicle's Uconnect system.

5th-wheel & gooseneck

The 2021 Ram 2500, particularly with the 6.7L Cummins Turbo Diesel engine, is well-suited for 5th-wheel and gooseneck towing applications. These methods distribute trailer weight more directly over the truck's rear axle, often allowing for higher towing capacities than conventional bumper-pull hitches.

• Max 5th-Wheel/Gooseneck Towing: Up to 19,680 lbs (with 6.7L Cummins Diesel, when properly configured).

For 5th-wheel and gooseneck towing, Ram offers a factory-installed prep package that includes mounting hardware and a bed-mounted 7-pin wiring connector. This makes the installation of aftermarket hitches much simpler and more secure.

Weight distribution & WDH requirements

For conventional trailers exceeding certain weights, typically around 5,000 lbs, a Weight Distributing Hitch (WDH) is often recommended or required for the 2021 Ram 2500. A WDH helps to distribute the trailer's tongue weight more evenly across all axles of the tow vehicle and trailer, restoring proper steering and braking control, and reducing stress on the rear suspension.

Always consult your owner's manual for specific WDH requirements based on your trailer's loaded weight and tongue weight. Proper setup and adjustment of a WDH are crucial for safe towing.

Real-world towing tips for this vehicle

• Know Your Weights: Always verify the actual weight of your loaded trailer, including cargo, water, and waste. Never exceed your truck's Gross Vehicle Weight Rating (GVWR), Gross Combined Weight Rating (GCWR), or individual axle weight ratings.
• Pre-Trip Inspection: Before every tow, check your tires (truck and trailer) for proper inflation and condition, ensure all lights are working, and confirm hitch connections are secure.
• Load Distribution: Distribute your trailer's cargo to achieve a tongue weight of 10-15% of the total trailer weight for conventional trailers. Too little or too much tongue weight can lead to dangerous sway or reduced handling.
• Brake Controller: If your trailer has electric brakes, ensure your integrated trailer brake controller is properly configured and functioning.
• Drive Safely: Allow for increased stopping distances, accelerate gradually, and anticipate turns and lane changes. Avoid sudden maneuvers.
• Monitor Temperatures: Keep an eye on your engine oil and transmission fluid temperatures, especially on long grades or in hot weather.

Common towing-related issues

Even with a capable truck like the Ram 2500, certain issues can arise during towing:

• Trailer Sway: Can be caused by improper weight distribution, high winds, or passing vehicles. Ensure proper tongue weight and consider using a sway control device if not integrated.
• Overheating: Pushing the truck too hard, especially on inclines, can lead to engine or transmission overheating. Monitor gauges and consider lower gears to prevent strain.
• Brake Wear: Increased weight puts more strain on your truck's braking system. Regularly inspect brake pads and rotors for wear.
• Tire Issues: Under-inflated or overloaded tires on both the truck and trailer can lead to blowouts or reduced stability. Always use tires rated for the load and ensure correct tire pressure.
• Electrical Problems: Trailer lights or brake functionality issues can often be traced back to faulty wiring or corrosion at the connectors. Regular inspection and dielectric grease can help.
