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 custom wiring connector provides a 4-way flat connector socket and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). 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.

A CURT gooseneck hitch is more than a necessary tool for towing; it is an integrated extension of your truck that allows you turn your 4×4 into the workhorse it was designed to be. Gooseneck hitches are stronger, tougher and more subtle than any other, and when quality craftsmanship and intelligent design become the fuel that drives a gooseneck hitch, you get a towing solution that leaves others lost for words. The CURT under-bed Double Lock gooseneck hitch is strong, fast and easy to operate. It gets its name from the two locking pins that engage the trailer ball and hold it in place, giving you twice the security when towing especially heavy trailers. The Double Lock mounts underneath your truck bed with compatible gooseneck installation brackets and provides a removable 2-5/16″ gooseneck trailer ball with a gross trailer weight capacity up to 30,000 lbs. and a tongue weight capacity of 7,500 lbs.

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).
