How to Measure for a Drop Hitch
Accurately measuring for a drop hitch is crucial for safe and level towing. An improper hitch height can lead to excessive trailer sway, uneven weight distribution, and potential damage to both your vehicle and trailer. This guide outlines the correct procedure for determining the necessary drop or rise for your towing setup.
Begin by parking your tow vehicle and trailer on a level surface. This ensures accurate measurements and eliminates variables introduced by uneven terrain. With the trailer coupled to the tow vehicle, measure from the ground to the top inside edge of the receiver tube opening. Next, measure from the ground to the bottom of the coupler on the trailer tongue.
Subtract the receiver height measurement from the coupler height measurement. A positive result indicates the need for a drop hitch, with the number representing the required drop in inches. A negative result indicates the need for a rise hitch, and the absolute value of the number represents the required rise in inches. For example, a coupler height of 18 inches and a receiver height of 14 inches indicates a need for a 4-inch drop (18 - 14 = 4). Conversely, a coupler height of 14 inches and a receiver height of 18 inches signifies a 4-inch rise is needed (14 - 18 = -4).
When selecting a drop hitch, consider the manufacturer’s recommendations for your specific vehicle and trailer combination. It’s generally advisable to choose a hitch with a slightly longer drop or rise than calculated to allow for variations in terrain and loading. Finally, after installing the hitch, re-measure to confirm that the trailer is level. Minor adjustments may be needed to achieve optimal towing performance.
People Also Ask About How to Measure for a Drop Hitch
What if my trailer isn’t level after installing the drop hitch?
If your trailer isn’t level after installing the drop hitch, double-check your initial measurements and ensure you’re using the correct drop/rise. Small discrepancies can sometimes be corrected by adjusting the trailer’s coupler height, if possible. If significant adjustments are required, you may need a different drop/rise hitch. Consider consulting with a towing specialist for expert advice if you’re unsure.
Can I use a drop hitch with a weight distribution hitch?
Yes, you can generally use a drop hitch with a weight distribution hitch. Ensure the shank of the weight distribution hitch is compatible with the drop hitch. Measure for the drop/rise after the weight distribution hitch is installed on the tow vehicle but before connecting the trailer. This accounts for any change in receiver height caused by the weight distribution hitch.
What is the difference between a drop hitch and a rise hitch?
A drop hitch lowers the connection point of the trailer, while a rise hitch raises it. A drop hitch is used when the trailer coupler is lower than the receiver hitch, whereas a rise hitch is necessary when the coupler sits higher than the receiver hitch.
How do I know what size shank I need for my drop hitch?
The shank size refers to the diameter and length of the portion that inserts into the receiver tube. Your receiver tube has a specific size (e.g., 2 inches), and the shank must match this diameter. The required shank length depends on the drop/rise you need and the clearance between your vehicle and trailer. Ensure adequate clearance to avoid contact between the trailer and your vehicle during turns.
