#4424 Horse/Gooseneck Trailer Adapter

PullRite's Horse/Gooseneck Trailer Adapter helps you avoid moving your hitch from a gooseneck to a fifth wheel hitch system.  By swapping out your trailer's coupler with the #4424, you can easily go back and forth between fifth wheel and gooseneck trailer quickly.

This Horse Trailer Adapter fits a standard 4" diameter, round gooseneck coupler of horse, cargo, stock or gooseneck trailers.  Works with all OEX Series Super 5thISR Series Super 5th and #3900 Single Point Super 5th (any PullRite hitch equipped with a hitch plate).

Features a removable wedge for use with all SuperGlide hitches too!  When used with your SuperGlide hitch, it can slide back on its rails to give you up to a 90° turn.  SuperGlide and this adapter is an especially great application for horse trailers with RV-style living quarters.

A towing system includes each vehicle and component involved in towing. Each item in your towing system has a capacity or weight rating.  You trailer has a Gross Vehicle Weight Rating, or GVWR.  Your truck has a tow capacity, payload capacity, and possibly more. In addition, your fifth wheel hitch has a weight rating.  This weight rating must be at, or above, the GVWR of your trailer for you to tow safely.  In addition, if your truck can tow larger loads (has a larger capacity) than the rating of your hitch, your system is only safe to tow loads at the lower rating, that of the hitch.

Your mounting kit also has a weight rating, just like your fifth wheel hitch. Many times, these rating are designed to match. But, this is not always the case. Your mounting kit may be higher rated then your fifth wheel hitch, but it also could be lower depending on the components involved.  The lowest rating of any one component in the system becomes the rating of the entire system. If your mounting kit is rated to 18,000 lbs., and your hitch is rated at 24,000 lbs., the weight rating of the entire system will not be above 18,000 lbs.  Other components in the system could lower the actual system rating further.

It is the end users responsibility to ensure a safe towing experience. To this end, it is your responsibility to ensure that the truck, trailer, hitching components, and all other items involved are rated or have a capacity sufficient for the loads involved.
