So last month on the Grandville Trailer blog we posted about the Weigh Safe Hitch that has tons of adjustable features, including, adjustable height. Now you may be asking yourself, ” How do I know the right tongue height for the trailer I am towing?” You may also be asking yourself, “What’s wrong with towing something with the trailer not level?” Well, I’m here to answer those questions for you.
Let’s start with learning what the right ball mount height is needed for the trailer you are towing. It’s no secret that both trailers and vehicles have different heights. The goal, when determining the height of the ball mount, is trying to keep the trailer as level as possible when driving down the road. First, you need to determine if you need our ball mount to have a rise or a drop. If the trailer coupler (the spot that rests on the ball mount), is taller than the receiving tube (the opening that the ball mount goes into on your vehicle), than you need your ball mount in the rise position. If the opposite is true than you need your ball mount in the drop position.
Now you are asking, “How much rise or drop do I need?” Well you can figure this out with a level and a measuring tape. First, make sure that your trailer is level, then measure from the ground to the bottom of the coupler. Next measure from the ground to the top of the receiving tube on your vehicle. The difference is the amount of drop or rise that you need.
Check out this video for a nice visual to walk you through the steps.
Now to answer the question about why the height of your trailer is important. The short answer is that it is easier to tow something at the right height. The longer answer is, if the tongue of the trailer is low, it puts stress on the suspension of the vehicle, along with making it more likely that you will feel the trailer sway. If the tongue of the trailer is too high, then it also puts stress on the suspension. I’ve heard that the trick is to have the tongue of the trailer slightly higher when it is empty so that it sits level when it is loaded.
I hope that this answers all the questions that you have about ball height!
