For newcomers, towing can be a bit intimidating. The awkwardness of the trailer’s added length, the increased acceleration and braking distances, and other new sensations and handling dynamics are a lot to think about. Then, there’s all the new equipment.

Selecting a trailer hitch ball may seem like a relief compared to navigating the rest of the hitch component market, but unfortunately, buying a hitch ball isn’t quite as straightforward as it seems. That said, a little bit of patience and knowledge can go a long way toward keeping everyone safe, secure, and stress-free. We designed this buying guide to help get you on the road as quickly and as smoothly as possible.

Contrary to what one might think, trailer hitch balls exist in more than one form, but when driving down the highway, most people rarely notice what type of ball is keeping that trailer in front of them from flying loose and smashing their bumper to smithereens. Fair enough, but when it comes to buying a trailer hitch ball, the type of ball suddenly becomes a significant consideration.

By and large, people looking for a “trailer hitch ball” are seeking a ball designed for use with a receiver hitch. Receiver hitch balls usually consist of a solid piece of steel formed into a ball and a threaded shank with a retention flare and a nut (and washer) to snug the ball onto the ball mount which then connects the ball to the receiver.

Receiver hitch balls usually fall into one of five rating categories which designate what trailer maximum weight a ball can safely handle. The majority of receiver hitch balls will fall within SAE Classes I through IV, especially for passenger vehicles and light duty trucks (like your F-150). Non-SAE “Class V” balls are much less common but are compatible with medium duty trucks, such as a dually pickup. Some Class V receiver hitch balls are designed specifically for pintle hitch setups, pulling double duty as both a hitch ball and a lunette ring hook.

When installed on a vehicle, gooseneck hitch balls bear a remarkable resemblance to the more common receiver hitch ball, but when compared side by side, these hitch ball types display distinct differences from one another. While receiver balls include a threaded shank and other smaller features, a gooseneck hitch ball features a smooth, solid metal shank (either round or square, depending on the particular hitch manufacturer) with a pin hole, detent-style retention system, or some other locking system to secure the ball to the hitch frame.

Without exception, these balls are rated for some pretty serious towing, usually falling with the Class V category of hitch ball weight ratings. As such, gooseneck hitch balls usually measure a wide 2 5/16 inches in diameter, and they can always be found mounted directly over the host vehicle’s rear axle.

Buying a trailer hitch ball isn’t quite as simple as picking up a half gallon of your favorite ice cream. Unless you have no regard for the life of your vehicle and towing equipment (or your life), then selecting a hitch ball takes some serious consideration. Make sure to pay attention to the details before spending that hard-earned cash.

When selecting a trailer hitch ball, ALWAYS learn about your vehicle’s towing capacity and the weight class rating of your hitch. There is no point in purchasing a Class V ball for your second hand Honda Accord. If, however, you goofed and installed a tiny Class II hitch on your brand-new Ram, buying a ball with a Class III or higher rating, you are setting yourself up for disaster.

Years ago, SAE International (“SAE” for short) established a weight class rating system for trailer hitches and their associated components. SAE’s rating system includes four classes, and hitch manufacturers have developed a fifth class for heavy duty towing parts. Every hitch ball comes with a maximum weight rating, each based on factors like the ball diameter, shank length, and shank diameter. Class I towing components tap out at a mere 2,000 pounds (including trailer, cargo, and accessories) or less, while Class IV components boast a limit of up to 10,000 pounds. Also, watch out for components marked “Class III/IV” which can only handle Class IV loads with the help of weight distribution equipment.

Receiver and pintle hitch balls feature a threaded shank that slides through the hole in the ball mount or lunette hook mount. Purchasing a trailer hitch ball with the proper shank diameter is critical to a successful tow job. While a shank that is too large obviously will not fit into a smaller mount hole, a shank that is too small for the mount hole is just as problematic. Besides the obvious geometric issues, a mismatched shank and mount hole indicate differing component weight class ratings, a recipe for a towing disaster.

Most trailer hitch balls spend plenty of time exposed to the elements, and without the proper ball finish, keeping your hitch ball in tip-top condition can require quite a bit of upkeep. The majority of trailer hitch balls include a corrosion-resistant finish to minimize rust over time. The most common finishes include chrome plating, far and away the top choice, stainless steel plating, and zinc plating (usually gold zinc). On occasion, a manufacturer will take a different approach and use an odd-ball finish, such as black nickel plating. For heavy-duty applications, some balls skip the finish all-together, opting for a raw, forged steel surface.

A trailer hitch ball isn’t just for towing your camper. With one of these balls installed on your hitch, you’ll discover there are plenty of different products and other kinds of trailers that are compatible. You’ll enjoy plenty of towing versatility, and you’ll be able to hook up plenty of different vehicles to haul or carry whatever you need behind your car. Plus, you can easily swap out your hitch ball for a newer model as needed or when you’re ready for an upgrade.

A trailer hitch ball is easy to install and easy to use. Compatible with your receiver and shank needs, a ball (once it’s in place) will enable you to easily haul the weight of your trailer and gear behind your car. These components are designed to be weighed down, exposed to the elements, and work seamlessly with your existing hitch. All of this ensures towing isn’t a hassle, especially when you’re hooking up your trailer and securing it to your hitch.

While trailer hitch balls are versatile in the sense that one ball can often work for different towing situations, these hitch additions can also be more specialized. If you’re working with a heavier weight class, unique towing situation, or even just a different kind of receiver, there’s a hitch ball that’ll have you covered. You can shop for specialized hitch balls to suit different towing needs and never have to worry about whether or not the ball is up for the job at hand.

On average, you can expect to spend between $10 and $25 for a trailer hitch ball. If you’re looking for an extra heavy-duty ball, or you need a higher class for what you’re towing, you may find yourself spending more than $25. Additionally, if you’re opting for a trailer hitch ball and other components sold together as a starter kit or comprehensive towing setup, you may spend upwards of $35.

As with something you do for decades upon decades, you pick up a few tips and tricks along the way in terms of selecting the right product, and/or using it. That’s the case with us and trailer hitch balls. To help you bridge the information gap, here’s a selection of what we’ve learned along the way.

You’ve got questions. The Drive has answers!

While not every hitch style requires a ball, many do, and receiver hitches, the most common hitch type found on passenger vehicles and light duty trucks, always require a ball.

Standard trailer hitch balls come in at a two-inch diameter, although maximum weight ratings may vary from ball to ball.

While ball sizing may be standardized, each ball’s maximum trailering weight will vary according to its weight class rating (Classes I through V) which is based on gross towing weight (GTW) and tongue weight (TW) ratings.

Theoretically, yes, but we strongly recommend against doing so. Your vehicle will still only be able to handle Class I loads. For safety reasons, NEVER use towing accessories with a different rating than your hitch. Samesies means safety.

If you tow often or store your trailer hitch ball in a location that is regularly exposed to the elements, then greasing your hitch ball is a wise idea.
