What is the towing capacity of the 2024 Chevy 2500 gas engine?

The maximum towing capacity for the 2024 Silverado 2500HD with the 6.6-liter gasoline V8 is about 18,500 pounds when properly equipped; actual capacity varies by configuration and options.

Overview: the gas-engine towing figure

The 6.6L V8 gasoline engine in the Silverado 2500HD delivers 401 horsepower and 464 lb-ft of torque. With the available Max Trailering Package, GM publishes a top towing figure of roughly 18,500 pounds. The exact rating depends on drivetrain (2WD vs. 4WD), rear-axle ratio, cab/bed configuration, and whether the Max Trailering Package and other tow-focused equipment are installed.

Before diving into specifics, note that towing numbers are published for defined configurations. Your truck’s actual towing capability will vary based on how it’s equipped and how you match it to a trailer’s weight and brakes.

With that in mind, the following sections break down the factors that influence the rating and the configurations commonly associated with the higher end of the gas-engine towing figure.

Below is a detailed look at the elements that determine the gas-engine towing capacity and how buyers can interpret the numbers.

Key factors that influence the gas-engine towing rating

The official towing number is not a single static figure; it reflects a combination of powertrain, gearing, and tow-specific equipment. The following factors commonly shape the maximum rating for the 2024 Silverado 2500HD with the gas engine.

• Engine and powertrain: 6.6L V8 gasoline engine provides the core pulling power (401 hp, 464 lb-ft).


• Drivetrain: 2WD or 4WD configuration can affect the published rating; specific numbers are published for each setup.


• Rear axle ratio: A higher numerical ratio (such as 4.10:1) typically supports higher tow capacity.


• Towing package: The Max Trailering Package or equivalent tow-oriented options are often required to reach the top rating.


• Cab/bed configuration: Different body setups (crew cab, extended cab, short/long bed) influence vehicle weight and suspension tuning, impacting the tow rating.


• Trailer equipment: Proper trailer brakes, hitch, and weight-distribution hardware are treated as part of the overall tow system in the rating.

Conclusion: The official maximum (around 18,500 pounds) is achievable only when the truck is built and configured to GM’s high-tow specification. Always check the exact figure on your vehicle’s build sheet and in the owner's manual.

Configurations commonly associated with the maximum rating

The following configurations are typically cited by GM as enabling the higher end of the gas-engine towing capability. Each element matters when interpreting the rating for a specific pickup.

• 6.6L V8 gasoline engine (the gas option in the Silverado 2500HD)


• Max Trailering Package (towing-focused enhancements)


• Rear axle ratio 4.10:1 (where available)


• Two-wheel drive (2WD) configuration in the appropriate cab/bed setup


• Appropriately matched trailer equipment, including trailer brakes and a weight-distribution hitch

In practice, verify the exact rating for your particular build and follow GM’s towing guidelines to ensure safe operation.

Practical guidance for planning to tow with the gas engine

When planning a tow with the 2024 Silverado 2500HD’s gas engine, consider how weight, configuration, and equipment interact to determine safe, legal towing capabilities. Use the following guidelines to plan responsibly.

• Check the official tow rating for your exact build from the window sticker or build sheet.


• Install and use the appropriate towing package and hitch rated for your trailer’s weight.


• Factor in payload and passenger cargo; payload reduces how much trailer you can tow safely.


• Utilize trailer brakes and a weight-distribution hitch for heavier loads to improve control and stopping power.

Bottom line: The gas-engine option can approach around 18,500 pounds of towing capacity in the right configuration, but always rely on the vehicle’s official specification for safe towing.

Summary

The 2024 Chevy Silverado 2500HD with the 6.6-liter gas V8 can tow up to about 18,500 pounds when properly equipped. Real-world towing depends on the exact configuration, including axle ratio, drivetrain, and optional towing packages, so always confirm your truck’s specific rating and follow GM’s guidelines for safe towing.

What is the gas mileage on a Chevy 2500 6.6 gas engine?

A Chevy 2500 with the 6.6L gas engine gets approximately 13 to 16 mpg in mixed driving, but this can vary significantly based on driving conditions and the specific trim level. Some users report lower mileage, especially with heavier loads or after the engine is broken in, while others see slightly better results, especially on the highway.
 
Factors influencing MPG

• Driving conditions: City versus highway driving, speed, and "start and stop" use all affect mileage. 
• Vehicle load: Towing or carrying heavy loads will significantly decrease fuel efficiency. 
• Trim level: Certain trims may have slightly different EPA estimates, though real-world mileage varies. 
• Engine break-in: Early mileage may be lower until the engine is fully broken in. 

Average expected mileage

• Mixed driving: Around 13 to 16 mpg. 
• Highway driving: Closer to 16 to 21 mpg for some trims, but often lower due to the truck's size and weight. 
• Towing: Lower, often in the single digits, depending on the trailer weight and conditions.
