Questions and answers of the customers

    I have an older horse/stock trailer that has a square outer gooseneck tube measuring approximately 4.5". Is this guaranteed to fit, or would I be better off replacing the outer tube with a weld on as well? Thanks for your help.

    With finding the right hitch you will want to measure the stem on the coupler. Also note that it would be best to remove the stem and measure the top to make sure which size stem you need.

    We are wondering if your gooseneck stem has holes that are straight across OR if it is slightly angled 10-30 degrees, where the stem hitch pin is off set or at an angle. Below is a picture of an angled stem, which we would use a stem with slotted holes to fit this angled pin.
