Question:

Inquiry: Rise of Euro Mount Ball Mounts Dear Customer Service: A Curt video How to Choose a Ball Mount and Trailer Ball describes the ball mount /rise as the vertical distance from the top of the receiver tube opening 13 to the bottom of the trailer coupler 17.6. I am looking for a euro mount 2inch ball mount with a rise of approximately 4.6inch 17.6 minus 13. What is the rise for the CURT Euro Mount Ball Mounts #45572 and #C45562? I find it confusing in that for the #45572 I have found 3 different distances published: Ball Heightinch of 4-5/8 http://www.curtmfg.com/part/45572 Riseinch of 2-5/8 https://www.etrailer.com/Ball-Mounts/Curt/C45572.html 3-3/8inch as shown in a dimensioned photograph https://www.etrailer.com/question-148126.html Sincerely, Ben Gardner P.S. I also submitted this inquiry to the curt website but have not received a reply yet.

The nature of the Euro ball mount design, which has a curved shank and a shorter actual ball height than a free-standing hitch ball like # 19258, can allow for multiple interpretations of the actual rise. Not to worry.

What I did for you was go to our warehouse and measure these two items. For the time being please ignore the specs and if you would use the following dimension I took on each ball mount. What I did was measure the distance from the TOP of the square shank to the TOP of the hitch ball.

For part # C45572 this distance is 5-1/2-inches. For part # C45562 this distance is 6-1/2-inches.

Please do note one thing about ball mount selection. A trailer's tongue weight (TW) that pushes down on the hitch ball will naturally cause some degree of "squat" at the rear end of the tow vehicle. This is absolutely normal. Since that amount of squat is often about 1-inch or 1-1/2-inches it is perfectly fine to choose a ball mount whose unhitched top-of-ball height is that same 1-inch or 1-1/2-inches HIGHER than the coupler. It evens out once the two are hitched and the trailer frame will then end up level with the ground.

Trailers tow better and have less sway when their frames are level to the ground when they are hitched.
