Today we're going to show you how to measure for a weight distribution shank. It looks kind of confusing with the different lengths and amount of holes on it and different measurements. We're going to keep it basic and simple so you can pick out the right one the first time and we'll show the steps that are needed to do that. First thing we do is get two measurements, we need to measure from the bottom of the coupler down to the ground. Also we need to measure from the top of the hitch opening down to the ground. The difference between the two measurements will tell us what size shank to get. We'll make that 13 1/2 inches and looks like we have a measurement of 21 inches. With some simple math, the difference will be 7 1/2 inches, so we need to find a drop that is close to that. The closest one we have is part # 3344. That part will have a eight inch drop total so that will be as close as we can get. We'll check that out to make sure it works. With our measurements in hand, lets go ahead and test it. As you can see the ball height is the same as the coupler so it looks like a perfect match.
