Trailer Hitch Ball Mount

What a ball mount is

A ball mount is the steel shank and platform that slides into the receiver and supports the hitch ball. It sets how high the ball sits, and it carries the tongue weight of the trailer. The listings here include classic fixed mounts, adjustable mounts with a set of holes or pivoting channel, loaded mounts that come with a ball, and multi-ball mounts that carry two or three ball sizes.

Choosing the class and size

The mount must match the receiver opening. Class I and II mounts typically use a 1-1/4 inch shank, and class III through V mounts normally use a 2 inch shank. A mount for a larger class is generally heavier and rated for more weight. Look for the class in the product title, and note that the ratings listed are the maximum for that mount, not a license to tow beyond your vehicle's limit.

• Drop or rise: Chosen so the trailer sits level, measured from the ground to the receiver and the coupler.
• Ball hole size: Common sizes like 3/4 inch and 1 inch must match the hitch ball shank diameter.
• Finish: Black powder coat or similar finishes resist rust.

Specs to compare

Compare the gross trailer weight rating and the tongue weight rating, both of which should be above what you plan to tow. Check the shank length and the total length from receiver to ball, because a longer mount can clear a bumper or spare tire but may increase leverage on the receiver. Fixed ball hole designs have a ball already built in, while open-hole mounts need a separate ball. Forged mounts are a strong option for heavier loads.

Safety and installation notes

Set your trailer level for the most stable towing and proper brake performance. Use a locking hitch pin and a clip, and torque the hitch ball nut to the manufacturer's specification. Adjustable mounts add flexibility, but check the hardware regularly for wear and tightness, and make sure the rating covers your trailer.

Your receiver, ball mount, ball and coupler each have a rating, and the lowest one governs your setup. Verify the vehicle's tow rating in the owner's manual, and consult a hitch professional for heavy trailers or weight distribution systems. Confirm that Jeep or vehicle-specific adapters match your exact year, make and model before choosing.

Matching parts and common mistakes

A ball mount works as part of a system, so check each piece before towing. The hitch ball must match the coupler size and have a rating at least equal to the trailer, and the ball must be mounted with the proper shank diameter and the flat washer and lock washer or nut that came with it. The pin must fit the receiver holes, and some mounts need a different pin diameter depending on class.

Frequent mistakes include selecting too much drop, which leaves the coupler too high on the ball, and not enough, which leaves the trailer tilted nose-down. Another is assuming a mount from one brand has the same hole pattern for pins as another. Using a drop mount upside down as a rise mount is possible only when the manufacturer says so, because the markings and hardware may be one-way.

For maintenance, check for cracked welds, bent shanks and rust, particularly where the shank meets the platform. Clean threads and apply a light coat of grease to the ball only where the manufacturer recommends. Replace any mount that has been overloaded or bent, since a damaged mount can fail suddenly.
