Today on our 2011 GMC Sierra well be test
fitting the Convert-a-ball cushioned ball mount for 2-inch hitches with a 3/4-inch rise
or a 2-inch drop rated at 10,000 pounds, part number amsc2. Before we begin our test fit we will first
need to obtain the hitch height of our vehicle. The hitch height is the measurement from the
ground to the inside top of the receiver tube. The hitch height on our vehicle is 17 inches. Keep in mind this measurement may vary due
to hitch style, tire size, or aftermarket accessories. Well now begin our test fit by sliding the
shank of the ball mount into the opening of the hitch.
