A CURT front trailer hitch allows you to use the front end of your vehicle for a variety of towing applications. They can be used for mounting a winch, a snow plow, a number of towing accessories and can even be used for some trailering applications.

At the boat ramp, your boat trailer can be hitched up to the front receiver hitch, giving you better control over the trailer as you launch. Some of the other accessories that can be used with a front tow hitch are the CURT winch mount, step pad, license plate holder, spare tire mount, skid shield and tow hooks.
