The tool used to determine the necessary height adjustment for a trailer hitch receiver is critical for safe and level towing. This instrument considers the height difference between the vehicle’s hitch receiver and the trailer’s coupler to calculate the optimal drop or rise needed in the hitch. For instance, if a truck’s receiver sits higher than the trailer’s coupler, the calculation will indicate the required drop length.
Proper hitch alignment is paramount for stable towing, preventing issues like trailer sway and uneven tire wear. Historically, achieving the correct alignment involved manual measurement and estimation, leading to potential inaccuracies. This calculation provides a precise and repeatable method, increasing safety and reducing the risk of equipment damage. It helps ensure the trailer rides level, maximizing aerodynamic efficiency and improving fuel economy.
