If you’re purchasing a new trailer hitch, you may be wondering what the difference is between a Class 3 and Class 4 hitch.
Both are designed for towing trailers, but they have different weight capacities.
Here’s a breakdown of how each class Hitch works and how much it can tow.
Class 3 vs Class 4 hitch
The main differences between a Class 3 and Class 4 trailer hitch are weight and tongue weight capacity.
A Class 3 hitch has a maximum weight capacity of 8,000 pounds and a maximum tongue weight of 800 pounds.
A Class 4 hitch has a maximum weight capacity of 10,000 pounds and a maximum tongue weight of 1,000 pounds.
| Class III | Class IV |
|---|---|
| Weight capacity of up to 8,000 pounds (3,629 kg) | Weight capacity of up to 10,000 pounds (4,536 kg) |
| Tongue weight capacity of up to 800 pounds (363 kg) | Tongue weight capacity of up to 1,000 pounds (554 kg) |
Comparison: Class 3 vs Class 4 hitch
First thing first, class 4 hitches are not nearly as common as class 3.
Yet, they are larger and they have their tasks to pull. So, let’s figure out which tasks require which hitch.
Receiver size:
If you have been in towing for some time now, you probably know that the receiver size doesn’t really matter in most types of hitches.
Yet, for the sake of comparison, we tell you that, both these hitches have the same size receiver. It is 2 inches.
So, it won’t make any difference in terms of receiver size. The real distinguishing factors are to be discussed ahead.
The towing capacity:
Now, you get to decide what you are going to pull. Once you have bought any of the hitches, you cannot really pull anything than their maximum limit permits.
You can pull a maximum of 8, 000 pounds using a category 3 hitch, the overall capacity being 3,500 to 8,000 lbs.
On the other hand, you can effortlessly pull up to 10, 000 pounds using a category 4 hitch.
So, based on this towing capacity, what you can pull using the hitches also vary.
The specifications of each hitch determine how much weight it can bear and how it may be distributed.
So, before making a purchase, you should always examine the characteristics of each individual hitch.
What you can pull:
Now that you cannot go beyond the prescribed maximum pulling capacity, you cannot pull a heavy-duty and large full-sized vehicle with a category 3 hitch.
When you have to pull large recreational vehicles or boats, the weight goes beyond 8, 000 pounds.
The same goes for heavy-duty full-sized vehicles. They stand firmly over 8, 000 pounds. So, in this case, you will need a class 4 hitch to do the job effortlessly.
So, what about the class 3 hitches? Well, they can pretty much pull most of the full-sized pickup trucks and passenger vehicles with the weight in consideration.
The standard, ordinary-sized vans, crossovers, and SUVs can easily match with a category 3 hitch.
Let’s put this another way, whatever you want to pull, keep the towing capacity as the first consideration.
Remember never to overburden the hitch and risk property and life.
Tongue weight capacity:
Tongue weight capacity is another factor that reveals how much stronger the hitches get with each developed category.
Compared to the category 2 hitches, a category 3 hitch offers 350 and 800 lbs. more tongue weight capacity.
But, compared to a category 3 hitch, a category 4 hitch offer nearly 1000 lbs. more tongue weight capacity.
Weight distribution:
Never mix up the towing capacity of the hitch with the overall distribution efficiency.
No matter which type of hitch you use, adding a drawbar with a higher class will not boost the hitch’s capacity to pull a trailer.
Always be sure to make use of a weight-distributing hitch if you need to evenly disperse weight.
Which type of trailer hitch is best Between Class 3 And Class 4?
If you’re looking to tow a small to medium-sized trailer, a Class 3 hitch will likely suffice.
However, if you’re looking to tow a large or heavy trailer, you’ll need to go with a Class 4 hitch.
- Class 3 hitches are typically smaller and lighter duty than Class 4 hitches, making them better suited for lighter trailers such as popup campers or small utility trailers.
- Class 4 hitches, on the other hand, are larger and heavier duty, making them better suited for bigger trailers such as RVs or boat trailers.
