Curt EZr Double Lock Gooseneck Hitch Operation

Curt EZr Double Lock Gooseneck Trailer Hitch Operation

The Curt EZr Double Lock underbed gooseneck trailer hitch provides a sturdy, secure connection for towing your gooseneck trailer and also allows for a clean, unobtrusive look for your truck bed when you aren't towing. To tow, simply pull the included handle out to unlock the hitch. Then insert the chrome-plated hitch ball into the ball hole. You may need to rotate the ball to line it up with the dual locking pins. When the ball drops into place, rotate the handle counterclockwise until the locking pins snap into position. Because there are 2 locking pins instead of 1, you get extra security for your towing setup.


Get full bed access when you're not towing. Just remove the ball, flip it upside down, drop it back into the ball hole of the hitch, and use the handle to lock the ball in place. A rubber cover is included with the EZr Double Lock. When the ball is stowed upside down in the hitch, place this cover over the ball hole to keep out dirt and grime and create a clean look for your vehicle.


Curt Center Locator Tool

Curt Center Locator for Double Lock Gooseneck Trailer Hitch

The innovative center locator tool included with this gooseneck trailer hitch is designed to make installation fast and easy by eliminating the need to measure where the ball hole must be cut into your truck bed. Once you have the custom installation kit in place and the gooseneck hitch is properly attached to the rails, the bright orange locator will help you to finish installation.


Curt Center Locator for Drilling Pilot Hole

Use the hole at the center of the locator to line up your 3/16" drill bit, and drill up from beneath the bed to create a pilot hole. This pilot hole will be your guide as you cut the 4" diameter ball hole into your truck bed.


Curt Center Locator for Drilling Ball Hole in Truck Bed

When you begin cutting through your bed, the locator will act as a trim shield, ensuring that you don't drill too deep. Continue cutting from the top of your truck bed until orange shavings appear. Once you see these shavings, you've gone far enough. The center locator can be easily removed from the hitch once installation is complete.

  • Recommended Gooseneck Hitch For A 2022 GMC Sierra 2500 HD Short Bed Double cab
    The OEM Prep Package on your 2022 GMC Sierra 2500HD will appear as 5 holes in the bed. Four going around in a rectangle with one in the middle (see the included picture). If you have this in your bed, you do have the prep package and actually already have a gooseneck hitch, so you will need the Curt Ball and Safety Chain Loop Kit # C60692. This will use the center hole for the goose ball and the back two holes for the safety chain loops. However, if you do not have the 5 holes in your...

  • Offset Gooseneck Ball Hitch Options For a 2020 Chevrolet Silverado 2500HD
    The Curt Custom Underbed OEM-Style Gooseneck Trailer Hitch # C60642 on your 2020 Chevrolet Silverado 2500HD will not allow for a offset ball. This is due to it not having a locking pin that travels through the shank of the ball like the Curt EZr Double Lock # C65HR or B&W Turnoverball # BWGNRK1020. Of these systems I recommend the B&W Turnoverball # BWGNRK1020 as the best option. You are able to store the ball in the same hole by simply turning it over to get a flat bed. And you can drop...

  • Reocmmended Curt Gooseneck Hitch for a 2025 GMC Sierra Short Bed
    Richard, I'm going to assume there was a typo with the bed length, and you meant to put 61" or 6'1" making this a short bed. If that's the case, then unfortunately the Curt RockerBall Multi-Fit Ball Kit w/ 4" Offset for Factory Gooseneck Hitches # C78ZV is not going to work. Instead, for the short bed you are going to need Curt Ball and Safety Chain Loop Kit for GM/Chevy/Ford/Nissan Underbed Gooseneck Trailer Hitch # C60692 if you have the prep package, or the Curt EZr Double Lock Underbed...
