The Different Types of Trailer Couplers

As part of a trailer hitch, trailer couplers are used to secure your fifth wheel or travel trailer in place while towing it on the road. You can securely pull and maneuver the trailer with your car due to its distinctive design.

The most common trailer coupler types are the A-shaped tongue and the straight tongue. In addition, trailer couplers come with a variety of mounting options, and you can even select the locking mechanism you like best.

Mounting Styles for Trailer Couplers

The right trailer tongue style can be the difference between a safe trip and an accident, so it's essential to know the different types on offer.

The three mounting styles for straight tongue couplers are:

Straight channel type

Straight-tongue style is the simplest and most common trailer coupler. Despite this, it does an excellent job and has a towing capacity ranging from 2,000 to 21,000 lbs.

The distinctive foldaway style

Straight tongues can also be used in this style. All you have to do to use this style is detach the pins and clip them in. You may also save some storage space by folding the tongue of the trailer. There is a weight limit of 5,000 to 9,000 lbs. It's one of the more common trailer hitch coupler types.

Round tongue style

The round shank tongue of this mounting style coupler is slipped into and welded onto, allowing it to lock into place. It has a spring-loaded collar to ensure a perfect fit. Ideal for utility trailers with lightweight generators, it can tow anywhere from 5,000 to 12,500 lbs.

Next, the five most common A-frame coupler types are:

Best for heavy loads: Flat mount style

A-shaped tongues can also be attached to the flat mount. They cater mainly to boat trailers and are heavy-duty trailer couplers, with a towing capability of between 14,000 and 25,000 lbs.

Best for versatility: Adjustable tongue mount

Towing trucks of varying heights can be accommodated by this sort of coupler. To place it on your trailer jack, you'll need an extra bracket, which is often offered separately.

Anywhere from 6,000 and 21,000 lbs is the towing capacity, meaning adjustable trailer couplers perfectly cater to individuals requiring both lighter and heavier loads. The weight capacity of these trailers is superior to most others.

Best for large trailers: Lunette ring mount

When it comes to A-frame trailers, the lunette ring mount makes things easier. Regarding bigger trailers or 5th wheels with a lot of overall weight, this mount is perfect. It has a towing capacity of 12,000 to 45,000 lbs.

If you're the owner of a larger trailer, you should strongly consider researching the characteristics of Lunette ring mounts.

Best for heavy trailers: Gooseneck coupler

This gooseneck trailer coupler is ideal for really hefty trailers since it is specifically designed for such use. It's used primarily on agricultural towing, as it has a towing capacity ranging from 20,000 to 40,000 lbs.

As the name might suggest, this coupler type is intended for use with gooseneck trailers only.

Best for enhancing braking features: Brake actuator

Because it features a connector that improves the braking capabilities activated on the tow vehicle, this sort of coupler is specifically designed to aid hydraulic brakes. It's an excellent choice since it gives your car more braking power. It has a towing capacity of 5,000–20,000 lbs.

The Different Trailer Hitch Ball Sizes

Trailer hitch balls have four typical sizes: 1-7/8", 2", 2-5/16", and 3". The size is determined by the hitch ball's diameter.

Choosing the right trailer ball

Towing capacity, receiver tube size, and the amount of rising and drop required to maintain a safe driving position are all factors to consider when choosing a ball mount. Finding out the size of trailer ball you need is easier once you know what you're working with, so be sure to check the manufacturer's advice.

A Hitch Explained

The towing vehicle's chassis is where a hitch is mounted. The trailer coupler connects to the hitch so that you can securely tow a fifth wheel. When towing your trailer, the hitch is designed to allow the trailer to swivel so that it is safe and secure.

Weight Carrying vs. Weight Distributing Hitches

These hitches are meant to carry the trailer's tongue weight on the rear of your vehicle. As a result, they're ideally suited for small to medium-sized trailers and fifth wheels.

Towing big trailers typically requires the use of weight-distribution hitches, which distribute the load evenly between both the towing vehicle and the large trailer. This results in better steering and braking control over the towing vehicle. Therefore, it's essential to choose a hitch that helps optimize both efficiency and safety on the road - take some time to really understand the differences before making your final decision.

Categories of Trailer Hitches

There are six distinct classifications of hitch types to differentiate between weight-carrying and weight-distribution hitch types. First, let's look at the various weight-bearing capacities.

The popular receiver hitch

Depending on the amount of weight they can tow, these hitches are already mounted on most tow vehicles. In the rear, they're mounted and might range in size from one inch by one inch up to two inches by two inches.

Durability, safety, and strength are all integrated into the receiver hitches. Five kinds of hitches are further subdivided depending on the quantity of weight they are capable of towing.

Best for camping: Front-mount hitch

This hitch is an excellent tool for boat owners needing to get their boats into or out of the water. You'll have a much better view of what you're doing when the boat is in front of you rather than behind!

The front-mount hitch is perfectly catered to individuals who enjoy spending time in nature and the outdoors. If you've got a 4x4 and do a lot of off-road adventures and camping, then you should probably look into getting a front-mouth hitch.

Best for flexibility: Bumper-mount hitch

Attaching this hitch to the vehicle is not necessary; instead, it's connected to the bumper rather than being freestanding. You may pull various things with this sort of hitch, such as camping trailers.

Best for heavy-duty towing: 5th wheel hitch

Heavy-duty towing necessitates a hitch with this kind of strength. It has a towing capacity between about 15,000 and 30,000 lbs, making it excellent for huge RVs.

The 5th wheel hitch utilizes a kingpin link rather than a ball and a coupler connection, which is essential to remember.

Ideal for heavy loads: Gooseneck hitch

Primarily comparable to a 5th wheel hitch is the gooseneck hitch. It uses a ball and coupler link, which is superior to the kingpin connection in terms of ease of usage.

The less obtrusive technique lets you utilize the whole truck bed when your vehicle isn't being towed. They can easily haul enormous trailers and are commonly used for heavy loads.

This is most commonly used in industries that deal with abnormal loads and require a hitch that won't buckle under extreme weight and pressure.

Best for construction: Pintle hitch

A lunette is required to connect your trailer to a pintle hitch, which is an entirely different system. Towing a large travel trailer with this sort of hitch can be done, but it's mainly primarily used in the construction sector due to its high noise level.

Ideal for large travel trailers: Weight distribution hitch

Your vehicle's rear receiver is outfitted with a weight-distribution hitch designed to distribute the trailer's weight equally. Your ability to control and steer can be significantly improved by the use of a weight distribution hitch. Since this hitch may boost your vehicle's towing capability, it's ideal for large trailer owners.

Optional extra: Trailer coupler lock

This is a lock you can put on your trailer's hitch when it isn't being towed in order to protect it from theft.

Final Thoughts

When deciding on trailer hitch couplers for your trailer or 5th wheel, understanding the differences between various types of couplers and hitches available can be helpful. Road safety will be significantly improved if you select the right hitch for your needs and your tow vehicle, especially if your gross trailer weight is considerably heavier than average.
