How to Measure Trailer Hitch Drop

A level trailer tracks straighter, brakes more evenly and keeps weight where the trailer maker intended. Getting there starts with one number: your hitch drop.

What you need

• A tape measure
• Level ground, with the truck loaded the way you normally tow
• The trailer sitting level on its jack

Step 1: Measure receiver height

Measure from the ground to the top inside edge of your receiver opening. Write it down as measurement A.

Step 2: Measure coupler height

With the trailer level, measure from the ground to the bottom of the trailer coupler. This is measurement B.

Step 3: Subtract

Drop = A − B. If the answer is positive, you need that much drop. If it is negative, you need rise.

Choosing a Rhino Hitch maximum drop

Rhino Hitch models are listed with a 7" or 10" maximum drop, measured from the top of the receiver. Pick a model whose maximum is at least your measured drop, with some room for a change in load or trailer.

Common mistakes

• Measuring with an empty truck when you normally tow loaded.
• Measuring to the center of the receiver instead of the top edge.
• Measuring a trailer that is nose-high or nose-low on its jack.
