Today, on our 2011 GMC Sierra, well be test
fitting the Rapid Hitch Adjustable Aluminum Ball Mount Kit with two chrome balls, with
the 5 inch drop, part number AM3410. Before we begin our test fit, we will firstly
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 has 17 inches. Keep in mind this measurement may vary due
to the hitch style, tire size, or aftermarket accessories. Well now begin our test fit in the drop position
by sliding the shank of the ball mount into the opening of
the hitch, we can then secure it with the pin and clip.
