When the hardest working truck meets the heaviest duty trailer, the Curt Double Lock EZr gooseneck hitch provides the strength and ease of operation necessary to put the two together. The Double Lock EZr offers the easiest possible installation, requiring only one person for the job. It uses a patented Center Locator to eliminate tedious measuring for the truck bed hole. It uses carriage bolts wherever possible to allow for one wrench tightening. It requires no truck bed removal, no welding, no sheet metal cutting. But the Double Lock EZr isn't just easy to install. Whether you're hauling livestock out to the farm or pulling some heavy-duty machinery to the jobsite, the Double Lock EZr offers safe, reliable towing and thorough SAE J2638 testing. To keep it well protected from rust and the elements, the Double Lock EZr is shielded in a highly durable carbide black powder coat finish. It also comes with a chrome trim ring, a rubber trim ring and a rubber hole cover for the truck bed hole. These components provide a finished look in the truck bed and keep rain, dirt and debris out of the trailer ball hole.
