They've made the truck said to turn the world under its tires and the trailer that moves mountains in a day. But what about the hitch powerful enough to connect the two? The Curt Manufacturing Double Lock EZr gooseneck hitch boasts easier installation, easier operation and 30,000 lbs. of towing capacity to make towing that oversize gooseneck trailer look easy. To make things even easier, this gooseneck hitch kit includes both the under-bed gooseneck hitch and the vehicle-specific installation brackets. The combined kit makes it simple to get your truck ready for towing by eliminating the need to purchase two different parts. It includes the #60619 gooseneck hitch and the #60648 installation brackets to fit certain years of the Chevy Silverado or GMC Sierra 2500, 2500 HD, 3500 and 3500 HD (for a complete listing of compatibility, see the Curt Manufacturing application guide). Installation of the Double Lock EZr requires only one person, using retainer clips to keep bolts secure and the center section fully supported while mounting it into place. It also uses our patented center locator to eliminate meticulous measuring and ensure error-free drilling. The EZr also uses carriage bolts whenever possible for one-wrench tightening. Operation of the Double Lock EZr is simple and safe. It uses two locking pins and a 3/8" diameter handle to keep the gooseneck ball locked into the center section. The ball features a flip-over design that allows you to store it inside the receiver hole when not in use, keeping your truck bed completely free of obstructions. With a fortified center section, this hitch offers a gross trailer weight capacity up to 30,000 lbs. and a vertical load limit of 7,500 lbs., giving you the power you need to get the job done right. This Curt Manufacturing Double Lock EZr gooseneck hitch kit features a durable carbide powder coat finish and includes a limited lifetime warranty. For safe, reliable towing you can count on, it is tested to meet proposed SAE J2638 standards.
