Difference Between Underslung and Overslung Coupler For Weight Distribution System
Question:
Is there an easy way to tell the difference between an under vs over slung hitch heads? Is there a measurement that can be taken to verify what model head I have?

An underslung trailer coupler is one that attaches to the bottom of the trailer frame and an overslung one is one that attaches to the top of the frame. Measuring is not required if you just take a look at your coupler and see where it attaches to the frame.
The Blue Ox SwayPro Weight Distribution w/ Sway Control - Clamp On - Underslung - 10K GTW, 1K TW part # BXW1003 is for weight distribution systems that have coupler that attach to the bottom of the frame. While the Blue Ox SwayPro Weight Distribution w/ Sway Control - Clamp On - 10,000 lbs GTW, 1,000 lbs part # BXW1006 work on standard overslung couplers.
The Blue Ox weight distribution systems are a good choice for your trailer if the loaded tongue weight is between 750 lbs and 1,000 lbs. The system also helps to prevent sway before it happens with the optimal points of tension in the system.
