Top 10 Hitch Accessories and Their Importance

Just as the perfect tie or scarf can elevate a dull outfit to a stunning look, the ideal trailer hitch accessories can determine the success of your towing experience.

It's not just about aesthetics. Many hitch accessories are engineered to ensure the safety of you, your passengers, your cargo, and others on the road. Safety should be your top priority, especially considering U.S. Department of Transportation statistics. The National Highway Traffic Safety Administration reports nearly 59,000 annual crashes involving passenger vehicles towing trailers, leading to injuries for over 28,000 individuals.

Fortunately, the majority of popular hitch accessories are both affordable and simple to install. Those few additional dollars and minutes can make a significant difference when transporting 5,000 pounds over 3,000 miles (or 2,268 kilograms across 4,828 kilometers). Let’s dive in.

Before exploring the Top 10 Hitch Accessories, a quick clarification is needed. Some towing experts might argue that certain items, like top-wind and swing-away jacks, should be categorized as trailer accessories. While this may be technically accurate, since a trailer and hitch function as one unit when connected, we believe this categorization is reasonable.

Now, let’s get started with ball mounts.

Hitch Accessory 10: Ball Mounts

Preparing to tow a trailer often centers on the hitch, but the hitch alone isn't enough. Essential accessories are crucial, as most factory-installed towing packages only include a hitch receiver attached to the vehicle. The hitch receiver, typically sized at 1.25 inches, 2 inches, or 2.5 inches, requires a separate ball mount that slides into it and is secured with a locking pin.

It's essential to ensure the ball mount aligns with your hitch's class, as this determines its towing capacity. Hitch classes are categorized into five levels, each with a specific weight limit.

Class I: 2,000 pounds (907 kilograms)

Class II: 3,500 pounds (1,588 kilograms)

Class III: 5,000 pounds (2,268 kilograms)

Class IV: 10,000 pounds (4,536 kilograms)

Class V: Greater than 10,000 pounds

Towing safely requires adhering to the lowest-rated weight capacity of any component. Purchasing a Class III ball mount for a Class II hitch is ineffective and unsafe.

Next, we'll explore what attaches to the ball mount.

Hitch Accessory 9: Hitch Balls

The hitch ball is another essential accessory, typically coated with stainless steel, chrome, or zinc, and often safeguarded by a rubber cover when not in use. The shank of the hitch ball inserts into a hole on the ball mount and is fastened with a nut and washer. Since ball mounts have varying hole sizes, it's crucial to ensure the shank diameter matches the mount's specifications. Similarly, the coupler, which connects the trailer to the tow vehicle, must align with the hitch ball's diameter for a proper fit.

Several towing product manufacturers provide interchangeable hitch ball sets, typically including two or three balls of different diameters. These sets allow users to tow various trailers with different couplers. Most interchangeable hitch balls feature a tool-free, quick-release mechanism, simplifying the process of switching between balls.

But how exactly do the hitch ball and ball mount link to the trailer?

Hitch Accessory 8: Couplers

Technically, the coupler is a trailer component, situated at the end of the tongue. However, it's considered a hitch accessory because it's essential for connecting the trailer to the vehicle. Couplers, like hitch balls and ball mounts, are rated by their weight capacity and must handle the gross trailer weight (GTW), which includes the trailer and its contents.

Couplers are available in two main types: A-frame and straight-tongue. A-frame couplers are designed for trailers with A-shaped tongues, while straight-tongue couplers fit trailers with straight tongues. Both types feature a hollow cup that fits over the hitch ball, so matching the coupler's diameter to the ball's is crucial. A spring-loaded latch secures the coupler to the hitch ball once connected.

The more mechanisms ensuring the tow vehicle and payload remain secure, the better. This principle underpins the next hitch accessory on our list.

Hitch Accessory 7: Pins, Clips and Locks

Though small, the pin and clip are indispensable hitch accessories. Together, they secure the ball mount to the hitch receiver. The pin is inserted through aligned holes in the receiver and ball mount, while the clip is placed over the pin's head to prevent it from slipping out.

Some trailer owners opt for a hitch lock, which combines the functions of a pin and clip while also deterring theft of the ball mount. Similarly, a coupler lock with a shank that fits into the coupler handle's locking hole safeguards the trailer from theft or tampering.

To streamline the purchase of hitch accessories, many manufacturers provide a towing starter kit. These kits typically include a hitch ball, ball mount, pin, and clip. Some versions replace the pin and clip with a lock and key system.

Hitch Accessory 6: Safety Chains

Safety chains are attached to each side of the trailer's tongue, each ending with an S-hook that connects to the hitch. In the event of a coupler or hitch ball failure, these chains keep the trailer tethered to the vehicle. Many trailer owners cross the chains beneath the tongue to prevent it from hitting the road during emergencies. They also ensure the chains have enough slack for turning but not so much that they drag on the ground.

Properly securing safety chains is a must every time you tow. Most states mandate this practice and also require that the chains and hooks be rated to support the gross trailer weight. Consult your local motor vehicle administration to understand the specific regulations that apply to you.

Next, we’ll explore a hitch accessory that offers customization and a touch of personal flair.

Hitch Accessory 5: Hitch Tube Covers

When not in use, your hitch receiver can collect dirt and be exposed to the elements. A hitch tube cover can protect it by fitting into the ball mount hole. These covers come in materials like plastic or forged steel, with steel offering a wide range of colors to match your vehicle. Branded covers also let you showcase your personality or support for a team, school, or organization. For more details, check out How Hitch Covers Work.

Another versatile option is the hitch step, which fits into the hitch receiver like a tube cover. It serves dual purposes: protecting the ball mount hole and providing a stable step to reach roof racks or truck beds.

Hitch Accessory 4: Cargo Carriers

While hitches are typically used for towing trailers, they can also be utilized for other purposes when not in use. A hitch-mounted cargo carrier is a versatile accessory that fits into the hitch receiver and offers a flat platform capable of holding up to 600 pounds (272 kilograms). It’s perfect for transporting items like camping gear, hunting equipment, lumber, or gardening tools.

Cargo carriers come in two main types. Open-style carriers may feature side rails to secure cargo and often include attachment holes for bungee cords or straps. They are made from materials like polypropylene or steel. Enclosed carriers, on the other hand, have lockable lids for added security and are available in stationary or swing-away designs.

Hitch Accessory 3: Adapters and Extenders

Many hitch-mounted accessories need extra equipment to function properly. For instance, if the shank of a ball mount or accessory doesn’t match the hitch receiver’s size, an adapter can bridge the gap. Adapters can either increase (e.g., 1.25-inch to 2-inch or 3.2 cm to 5.1 cm) or decrease (e.g., 2-inch to 1.25-inch) the receiver size to ensure compatibility.

A hitch extender provides additional clearance for hitch-mounted accessories. This is particularly useful for vehicles with a rear-mounted spare tire or a camper shell extending beyond the bumper. Even without these features, an extender may be needed if the hitch is positioned far beneath the bumper. Essentially, it shifts the hitch receiver forward by 6 to 12 inches (15 cm to 31 cm), allowing the use of accessories like a bike rack or cargo carrier.

Only two hitch accessories remain. What’s next on the list?

Hitch Accessory 2: Weight Distribution Systems

For towing loads exceeding 3,500 pounds (1,588 kilograms), consider installing a weight distribution system. These systems are often sold as kits containing a hitch head, shank, and spring bars. The hitch head serves as the main connection point, attaching to the shank on one side and the spring bars on the other. The spring bars connect to the trailer, while the hitch ball is mounted on top of the hitch head and fits into the coupler.

The system works by leveraging the trailer tongue and tow vehicle to distribute the trailer's weight across both axles. This enhances stability, improves braking and steering control, and ensures a safer towing experience—benefits every driver can appreciate.

And now, moving on to the number one accessory.

Hitch Accessory 1: Trailer Jacks

A trailer jack, though mounted to the trailer rather than the hitch, plays a crucial role in making hitching easier and safer. Trailer jacks are positioned on the tongue near the coupler and come in top-wind or side-wind styles. They can be cranked to adjust the trailer's height relative to the hitch ball during loading or unloading. Most jacks offer up to 25 inches (64 centimeters) of lift and support up to 800 pounds (363 kilograms). Additionally, many feature a swing-away design, allowing the jack to be stored above the road while towing.

For those who prefer not to manually crank their trailer, electric trailer jacks are an excellent alternative. These jacks are powered by DC motors and can handle loads of up to 3,500 pounds (1,588 kilograms).
