Adjustable vs Fixed Ball Mount

This is one of the few decisions in towing where the expensive answer is genuinely wrong for most people. An adjustable ball mount is a better product than a fixed one in almost every dimension that appears on a specification sheet, and it is the wrong buy for a reader with a single trailer. The question is not which is better engineered. It is how many coupler heights you own.

A fixed mount is a single forging with a ball on it. There is no joint, no second pin, no adjustment to creep. It weighs less, which matters because the mount comes out of the receiver and goes back in more often than any other part you own. And the good ones ship with the ball already fitted and torqued, which quietly removes the step owners get wrong most often.

That torque step deserves naming, because it is the strongest practical argument for a fixed mount. Published trailer ball mounting torque runs into the hundreds of ft-lb - CURT publishes 250 ft-lb for its 2 in stainless ball. That is well beyond a wrench and a firm pull, and an under-torqued ball nut works loose in service. The ball sizes reference covers the figure and why it is a specification rather than a suggestion. A loaded mount arrives with the job done.

• Lighter to carry and store. One piece of steel rather than a head, a shank and the hardware joining them.
• Fewer pre-trip checks. Pin and clip, and you are finished.
• Quieter. An adjustment joint is one more interface that can move under load.
• Cheaper, usually by a wide margin, and the money is better spent on sway control or a tongue weight scale.
• No torque job when the ball comes pre-fitted.

An adjustable mount solves one problem completely: more than one coupler height. If you own a boat trailer, a utility trailer and a camper, their couplers almost certainly sit at three different heights, and a fixed mount sized for one of them tows the other two nose-high or nose-low. That is not a comfort issue. A nose-high trailer shifts weight off the tongue and onto the rear trailer axle, which is the exact condition that produces sway.

The second real case is a drop you cannot buy fixed. Lifted trucks need more drop than the fixed catalog generally goes to, and stacking an adapter under a fixed mount is a worse answer than one adjustable mount rated for the job. The drop arithmetic for a lifted truck is worth doing before you shop either way.

• One mount for several trailers, which is the whole point.
• Two ball sizes on one head on most designs, so a 2 in and a 2-5/16 in coupler are both covered.
• Deeper drops available than the fixed catalog typically reaches.
• Some fold or flip so the ball is not at shin height in a parking lot.
• One version weighs the tongue for you, which replaces a separate tool and a trip to a scale.

Keeping to brackets rather than numbers, because prices move: a fixed loaded ball mount sits at the entry end of the hitch aisle, a steel adjustable mount lands in the middle, and an aluminum adjustable mount or one with a built-in scale sits at the top. The spread between the cheapest fixed mount and the most expensive adjustable one is large enough that it is worth asking what else that money could buy - a friction sway control bar, say, or a tongue weight scale, both of which address causes rather than convenience.

The exception is the mount with a scale in it. That one is not really competing with other mounts; it is competing with buying a mount and a scale separately, and against never measuring tongue weight at all. If you would honestly never measure the tongue weight any other way, it is the cheapest route to a number that matters more than anything else on this page.

1. Best fixed mount

CURT Loaded Ball Mount with 2 in Ball (2 in drop, 7,500 lb)

CURT · Best for one trailer at a known height

A one-piece mount with the ball already fitted and torqued, rated to 7,500 lb gross and 750 lb tongue with a 2 in drop. Nothing adjusts, which is exactly why nothing rattles or works loose.

Published specifications

Gross trailer weight

7,500 lb source

Tongue weight

750 lb source

Drop

2 in source

Ball diameter

2 in source

What works

• +Arrives with the ball fitted, so there is no torque step to get wrong
• +One piece means nothing to loosen or rattle
• +Light enough to leave in the receiver or throw in a toolbox

What does not

• −The 2 in drop is the only drop - measure before you buy
• −7,500 lb ceiling rules out heavier trailers

Skip it if

Useless on a lifted truck, where a 2 in drop will still leave the trailer nose-high and the weight on the rear axle of the trailer.

2. Best adjustable mount

B&W Tow & Stow Adjustable Ball Mount

B&W Trailer Hitches · Best for daily drivers that tow occasionally

Two balls on a pivoting head that tucks up under the bumper when nothing is attached, which is the part owners actually rave about - no more shin-height steel bar in a parking lot. Height adjusts in pin increments rather than continuously.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

• +Stows up out of the way instead of projecting behind the bumper
• +Two ball sizes on one head, flipped rather than swapped
• +Solid, heavily built, and quiet when pinned correctly

What does not

• −Heavy to handle and to store
• −Height steps are fixed by the pin holes, so an exact level may not be available

Skip it if

Not the right buy if you need a precise level height - a continuously adjustable channel mount will get closer than pin increments will.

3. Lightest adjustable

Andersen Rapid Hitch Aluminum Adjustable Ball Mount

Andersen Hitches · Best for anyone tired of lifting steel mounts

An aluminum adjustable mount, which is the point: a steel channel mount is genuinely heavy to carry, and this one is not. Balls thread into the stainless pin rather than bolting through a hole, so swapping sizes takes seconds.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

• +Dramatically lighter than a steel adjustable mount of similar capacity
• +Ball changes are a thread-on operation, not a torque-and-nut job
• +Aluminum does not rust streak down a painted bumper

What does not

• −Aluminum marks more easily than powder-coated steel
• −Capacity depends on which ball and pin combination you fit, so read the chart

Skip it if

Not the one if you leave the mount permanently in the receiver through salted winters - the convenience you are paying for is weight, and you would never be lifting it.

4. Cheapest adjustable

CURT Adjustable Channel Mount with Dual Ball (2 in shank, 6 in drop)

CURT · Best for garages with several trailers

One mount that covers two ball sizes and a range of heights, which is the answer when the garage contains a boat trailer, a utility trailer and a camper that all sit at different heights. Capacity drops to the lower-rated ball you are actually using.

Published specifications

Gross trailer weight

14,000 lb source

Ball capacities

2 in ball to 10,000 lb; 2-5/16 in ball to 14,000 lb source

Adjustment range

6 in maximum drop, 5-1/4 in maximum rise source

Receiver size

2 in source

What works

• +Two ball sizes and a height range in a single mount
• +Flipping it gives rise as well as drop
• +Rated to 14,000 lb on the larger ball

What does not

• −Heavy, and more joints means more places for rattle to start
• −The pins and bolts need checking for torque, unlike a one-piece mount

Skip it if

Pointless if you own one trailer and tow it with one truck - a fixed mount at the right height is lighter, quieter and cheaper.

5. Adjustable with a scale

Weigh Safe Adjustable Drop Hitch with Built-in Tongue Weight Scale

Weigh Safe · Best for owners who will never visit a scale

An adjustable drop hitch with a hydraulic gauge in the shank, so the tongue weight reads out as you lower the trailer onto the ball. It turns the single most-skipped step in towing into something that happens automatically, which is worth more than the hardware itself.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

• +Reads tongue weight every time you hitch, with no extra step
• +Adjustable height and reversible for rise as well as drop
• +Makes the 10-15 percent rule checkable instead of theoretical

What does not

• −The gauge reads at the ball, so it is sensitive to being parked on a slope
• −Heavier and considerably more expensive than a plain mount

Skip it if

Not needed if you already weigh at a public scale - the gauge is convenience, and a certified scale is still the more accurate number.

1. 1Buying adjustable for one trailer. You pay for range you will set once, carry the extra weight at every hitch-up, and add a joint to your pre-trip checks. A fixed mount in the right drop is the better part for that reader.
2. 2Buying fixed without measuring. A fixed mount is only right if the drop is right, and the drop is the measured difference between your trailer's level coupler height and your receiver height. Guessing is how people end up owning two fixed mounts and then an adjustable one.
3. 3Treating the ball size as a preference. Neither type changes this. The stamp on the coupler decides the ball, and a smaller ball will latch in a larger coupler and still come off under load.

If you are still unsure which camp you are in, the mechanism side of adjustable mounts - how the adjustment carries load, and what wears - is covered separately in the adjustable ball mount explainer, and the full field of mounts worth owning is in the ball mount roundup.

Two follow-ons. Among adjustable mounts, the Tow & Stow against the Weigh Safe compares the two designs people most often shortlist, and aluminum against steel decides how much the thing weighs in your hands.
