Double Lock EZr Gooseneck Installation Brackets

from

$383.99
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 under-bed Double Lock EZr gooseneck hitch features a gross trailer weight capacity up to 30,000 lbs., a vertical load limit of 7,500 lbs. and easier, more secure towing for your gooseneck trailer. Providing a solid foundation for the Double Lock EZr, this set of gooseneck installation brackets is designed for a vehicle-specific fit to maximize your pickup’s towing potential and integrate with the frame seamlessly. Installation with the CURT Double Lock EZr is fast and easy. Because the installation brackets are made vehicle-specific, they use pre-existing holes in the vehicle’s frame and require less drilling. The Double Lock EZr requires only one person during installation, using retainer clips to keep bolts secure and the center section fully supported while mounting it into place. It also uses carriage bolts whenever possible for one-wrench tightening and does not require the exhaust to be lowered during installation. This particular set of gooseneck installation brackets is specifically designed to mount the CURT Double Lock EZr gooseneck hitch #60619 on certain years of the Chevy Silverado and GMC Sierra 2500HD or 3500 (see application info to verify fitment). It features a laser-cut construction for a precise fit and is rated to the vehicle’s maximum gross trailer weight capacity. With each gooseneck installation bracket sub kit, we provide the necessary hardware for an easier installation, and we coat our gooseneck brackets in a liquid A-coat to make sure rust and other potential threats are not a problem.

Product Features:
  • Mounts the Double Lock EZr gooseneck hitch on specific pickup truck models
  • Vehicle-specific design optimizes strength and installation time
  • Constructed from high-strength, laser-cut steel for a precise fit
  • Protected by a rust-resistant liquid A-coat

CURT – Dual-Output 7/4-Way Connector (Plugs into USCAR) (Part No.55774)

Dual-Output 7/4-Way Connector (Plugs into USCAR)

from

$31.49
A CURT custom wiring connector (sometimes called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT’s custom wiring connectors come into play. A custom wiring connector uses a single original equipment plug to plug into a special socket provided by your vehicle. Though this option is not available on every vehicle, some automotive manufacturers design their vehicles to be easily equipped for towing by supplying a socket, integrated into the vehicle’s electrical system, to readily accept a custom wiring connector. With a CURT custom wiring connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom wiring connector actually provides two connector sockets for a multipurpose option. It plugs into an OEM connector and offers a 4-way flat and 7-way RV blade connector. It comes with a mounting bracket for easy installation and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment). CURT custom wiring connectors are designed to be long-lasting and simple to install. They come with dust covers to keep your connector clean when not in use.

Product Features:
  • Plugs into USCAR socket to provide 4-way and 7-way trailer wiring connectors
  • Fits USCAR-equipped vehicles with factory tow plugs only
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • 7-way RV blade socket adds reverse lights, electric brakes and auxiliary power
  • Dust covers included to keep connectors clean when not in use
  • Slit loom keeps wires contained and well protected
  • Metal bracket securely mounts wiring to the vehicle or trailer hitch
