How Much Can a Class 4 Truck Tow?

Class 4 trucks are some of the most popular mid-size commercial vehicles on the market, and for good reason. Not only are they powerful and reliable, but they also offer a lot of towing capacity. In fact, depending on the model, a class 4 truck can tow up to 20,000 pounds.

Class 4 trucks typically have GVWRs (Gross Vehicle Weight Ratings) between 14,000 and 16,500 pounds. That being said, the actual towing capacity of these vehicles can vary greatly depending on several factors such as engine type and size, transmission type and size, frame strength, suspension configuration and load carrying capacity.

Class 4 trucks can be equipped with either gasoline or diesel engines. Gasoline engines typically range in size from 5-8 liters while diesel engines are usually 7-10 liters in size. Generally speaking, the larger the engine size is, the higher the towing capacity will be.

The transmission type will also play a role in determining how much a class 4 truck can tow. Most class 4 trucks will come standard with manual transmissions but there are also some models that offer automatic transmissions as well. Again, generally speaking, manual transmissions tend to be more efficient when it comes to towing weight than automatic transmissions.

The frame strength is another important factor when it comes to determining how much a class 4 truck can tow. Frames that are made from heavy duty steel or aluminum will be able to handle more weight than frames made from lighter materials such as fiberglass or plastic composite materials.

Finally, suspension configuration and load carrying capacity play an important role in how much weight a class 4 truck can tow safely and efficiently. A vehicle with an independent front suspension system is better able to handle bumps in the road which helps reduce stress on the chassis when hauling heavy loads.

Conclusion:

All things considered, a class 4 truck can tow up to 20,000 pounds depending on its engine type and size, transmission type and size; frame strength; suspension configuration; and load carrying capacity. As always it’s important to remember that even if your vehicle has enough power for hauling heavy loads you should never exceed its recommended maximum payload rating.
