What Size Drop Hitch Should I Buy: All About Draw Bars

Hitching up your trailer requires a secure connection. This entails selecting the correct trailer hitch ball mount for your towing rig. Moreover, you need to make sure that the drawbar you purchase is of the proper size and weight capacity for your trailer.

What is a drop hitch?

As a driver, you should know that there are different types of hitches. A drop hitch is necessary when you need to tow a trailer that sits higher than your vehicle. This type of hitch provides extra clearance between the two vehicles. If your trailer tongue is higher than your vehicle's receiver, then you will need a drop hitch. This type of hitch will provide the necessary clearance to avoid any interference between the two vehicles.

A drop hitch receiver promises stability for your trailer-vehicle connection, so you won't have to worry about the possible loss of control due to an unbalanced load. You've probably spotted a car or truck struggling under the weight of an overloaded trailer, its rear end sagging like a burdened animal. Besides, a drop hitch will make it easier to back up your trailer.

A drawbar is the part of the hitch that extends from the trailer tongue to the vehicle's receiver. The drawbar supports the trailer tongue and provides a connection point for the safety chains. Drawbars come in different sizes, so it's important to select one that is compatible with your vehicle's receiver. There are two types of drawbars: fixed and removable. A fixed drawbar is welded or bolted to the trailer tongue, while a removable drawbar can be removed when not in use. If you have a large trailer, you may need a heavy-duty drawbar to provide sufficient support.

Does a drop hitch affect tongue weight?

In a nutshell, yes, tongue height has an impact on tongue weight. That is because the higher the trailer tongue, the more weight is transferred to the front of the vehicle. This can cause problems when braking and make the vehicle harder to control.

It is important to note that not all vehicles are able to handle increased tongue weight. Check your vehicle's owner manual to see what the maximum tongue weight rating is for your particular make and model. If you exceed this rating, you could damage your vehicle or cause an accident.

Do I need a drop hitch for my trailer?

The main reason you'll need a drop hitch is to keep the trailer level while it's connected to your tow truck. When towing, having a level trailer configuration is critical. Thus, if your trailer tongue is higher than the receiver on your truck, you will need a drop hitch to make up for the height difference.

Not only does a drop hitch keep your trailer level, but it also provides extra clearance between the two vehicles. This is important because it prevents the trailer tongue from hitting the back of your vehicle while you're driving.

What size drop hitch should I buy?

This is a question that we get asked a lot, and it's not always an easy one to answer. It depends on a few factors, including the type of vehicle you have, the type of trailer you're using, and your personal preferences.

If you're wondering what size draw bar/drop length is best for your tow vehicle, we recommend 11” of clearance from the bottom of your LOADED trailer hitch ball to the ground. You can find out how to achieve that by checking our blog which walks you through a step-by-step process.

The size of the drop hitch also depends on the width of your vehicle's receiver tube. Most receivers are either 2" or 2-1/2" wide. If you have a 2" receiver, you'll need a drop hitch that is also 2" wide. If you have a 2-1/2" receiver, you'll need a drop hitch that is 2-1/2" wide.

Moreover, when choosing a drop hitch, you'll need to decide if you want a fixed length or an adjustable length. A fixed length is just what it sounds like - it's one solid piece with no moving parts. An adjustable drop hitch has a telescoping feature that allows you to adjust the length of the bar. Both have their pros and cons. Fixed-length drop hitches are more affordable and easier to install. Adjustable drop hitches are more versatile and can be used with different vehicles and trailers.

At the end of the day, it's up to you to decide what size drop hitch is best for your needs.

What size drop length do I currently have?

If you don't want to make an expensive mistake, you should measure the draw bar with a tape measure or count the number of holes in the drop portion when the slider is not connected to figure out whether your roller has a ten-inch drop. You'll need to keep track of how many holes there are and then subtract three, which will tell you how long your roller has a 10" drop (13-3=10). Also, be sure to account for the thickness of your receiver.

For example, if you have a 2" receiver, the thickness of the receiver will add two inches to the length of the drop hitch. So, if you have a 10" drop hitch with a 2" receiver, the total length will be 12".

The only way to know for sure which size shank you need is to measure the inside opening of the receiver on your tow vehicle. Always take this measurement yourself, and never rely on someone else's estimation. Getting an accurate measurement is critical to ensure you get the right-sized shank.

How would I know that the drop hitch is compatible with my car?

A motorist must know the towing capacity of their vehicle before they can purchase the appropriate size drop hitch. The towing capacity is usually listed in the owner’s manual. If you no longer have your owner’s manual, you can find this information online or by contacting your local dealership.

You will also need to know the tongue weight of your trailer. The tongue weight is the amount of downward force exerted on the ball mounted by the trailer coupler. The following formula can be used to calculate the tongue weight:

  • Tongue Weight (TW) = Gross Trailer Weight (GTW) x 0.15
  • For example, if the GTW of your trailer is 4,000 lbs, the TW would be 600 lbs (4,000 x 0.15 = 600).

The TW should never exceed the maximum tongue weight capacity of your vehicle, which is typically between 10-15% of the total towing capacity.

What's the difference between a fixed length and an adjustable length drop hitch?

A fixed-length drop hitch is one solid piece with no moving parts. An adjustable drop hitch has a telescoping feature that allows you to adjust the length of the bar. Both have their pros and cons. Fixed-length drop hitches are more affordable and easier to install. Adjustable drop hitches are more versatile and can be used with different vehicles and trailers.

Conclusion

Picking the right size drop hitch can be a bit of a challenge. But with this guide, you should have all the information you need to make the best decision for your needs. Just remember to measure your receiver tube, know your vehicle's towing capacity, and tongue weight capacity, and you'll be good to go.
