What Is a Ball Hitch? Hitch vs. Ball Mount Explained

Category How To's
Quick answer

A trailer hitch receiver is the vehicle-mounted structure with a receiver opening. A ball mount is the removable part that slides into that receiver and holds the hitch ball. For heavier trailers, a weight distribution hitch adds spring arms and built-in or add-on sway control instead of placing all tongue weight directly on a standard ball mount.

Hitch vs. ball mount: what is the difference?

People often say “ball hitch” when they mean the complete towing connection. That shorthand is understandable, but the parts are not interchangeable. Your receiver hitch is attached to the tow vehicle. Your ball mount slides into the receiver tube. The hitch ball bolts to or is built into the ball mount, and the trailer coupler locks over the ball.

Trailer hitch receiver

The structural assembly attached to the tow vehicle. Its square receiver tube accepts compatible towing accessories. The receiver’s class, opening size and rating must support the complete setup.

Ball mount

The removable drawbar that fits the receiver and positions the hitch ball at the correct height. Fixed and adjustable ball mounts are available for different tow vehicles, trailers and rise/drop needs.

Hitch ball

The round connection point that matches the trailer coupler. Common ball diameters are 1-7/8, 2 and 2-5/16 inches, but the stamped coupler size—not a guess—determines the match.

Weight distribution hitch

A complete towing system that uses a hitch head and spring arms to distribute tongue weight across the tow vehicle and trailer axles. Some systems, including the Fastway e2™, also build sway control into the hitch.

Fastway tip: A bike rack, cargo carrier or mobility carrier may use a receiver, but it is not a ball mount. A ball mount is specifically designed to position a hitch ball for trailer towing.

How do hitch parts connect?

Reading the connection from the vehicle toward the trailer makes the system easier to understand:

Receiver hitch: mounted to the tow vehicle.
Ball-mount shank: inserted into the receiver opening.
Hitch pin or lock: secures the shank in the receiver.
Hitch ball: provides the connection point for the coupler.
Trailer coupler: closes and latches over the matching ball.
Safety equipment: chains, electrical connection and the breakaway cable complete the hookup where required.

Do you need a receiver, ball mount or weight distribution hitch?

Your situationWhat you likely needWhat to verify
Your vehicle has no receiver openingA vehicle-specific receiver hitch installationVehicle fitment, receiver class and towing ratings
You have a receiver and tow a conventional bumper-pull trailer within all ratingsA correctly sized fixed or adjustable ball mount and matching hitch ballReceiver size, rise/drop, ball size, GTW and tongue-weight ratings
You tow more than one trailer or switch tow vehiclesAn adjustable ball mount can make height changes fasterRequired drop/rise, receiver size and the rating of every component
Your loaded trailer creates rear sag, light steering or requires weight distributionA properly selected weight distribution hitchTow-vehicle, receiver and trailer instructions plus loaded tongue weight

No single chart replaces the tow-vehicle owner’s manual, receiver label, trailer ratings and equipment instructions. The lowest-rated component sets the limit for the complete system.

How do you choose the correct ball mount?

The right ball mount does more than fit the receiver. It must also place the trailer close to level and carry the actual load without exceeding any rating.

Confirm the receiver opening: commonly 2 or 2-1/2 inches.
Measure the rise or drop needed with the tow vehicle and trailer on level ground.
Match the hitch-ball diameter to the size stamped on the coupler.
Check gross trailer weight and tongue-weight ratings on every part.
Use a compatible hitch pin or locking system.
Recheck clearance through turns and over driveway transitions.

If trailer height varies, an adjustable setup can make it easier to match different vehicle-and-trailer combinations. Compare receiver sizes, drop ranges and ratings across the Fastway FLASH™ ball mount family.

When is a standard ball mount not enough?

A standard ball mount carries the trailer’s tongue weight at the rear of the tow vehicle. A weight distribution hitch uses spring arms to transfer a portion of that load across the axles, helping restore a more balanced towing stance. It does not increase the ratings of the tow vehicle, receiver or trailer.

You should investigate weight distribution when the tow-vehicle or receiver instructions require it, when the loaded trailer approaches the weight threshold listed by the manufacturer, or when the setup shows symptoms such as excessive rear squat or reduced front-axle loading. The Fastway e2™ Hitch combines weight distribution with built-in 2-point sway control in round-bar and trunnion styles.

Important: Select a weight distribution hitch from the trailer’s loaded tongue weight and gross trailer weight—not dry weight alone. Include cargo loaded behind the tow vehicle’s rear axle when the hitch manufacturer tells you to.

Build the right connection—not just one that fits

Choose a Fastway adjustable ball mount for correctly leveled conventional towing, or compare the e2™ Hitch when your setup calls for weight distribution and built-in sway control.

Hitch and ball mount FAQs

Is a ball mount the same as a hitch?

No. The hitch receiver is mounted to the vehicle; the ball mount is the removable component that slides into the receiver and carries the hitch ball.

What is a ball hitch?

“Ball hitch” is common shorthand for the towing connection made by a hitch ball and trailer coupler. When buying parts, identify the receiver, ball mount, hitch ball and coupler separately so their sizes and ratings match.

Can any ball mount fit any receiver?

No. The shank must match the receiver opening, and the ball mount must provide the required rise or drop while meeting or exceeding the actual gross trailer and tongue weights.

Can I use a ball mount upside down for rise?

Some ball mounts are rated for both drop and rise orientations; others are not. Follow the markings and manufacturer instructions for the exact model.

Does a weight distribution hitch replace a ball mount?

A weight distribution hitch uses its own shank and hitch-head assembly instead of a conventional stand-alone ball mount. It adds spring arms for load distribution and may include sway control.

Does a ball mount control trailer sway?

A conventional ball mount does not provide weight distribution or active sway control. If your towing setup calls for those functions, use equipment designed and rated for them.

Always follow the tow-vehicle, receiver, trailer and component manufacturers’ instructions. Verify current local requirements before towing.
