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. Using the heavy-duty operating handle, the trailer ball can be unlocked and flipped over whenever necessary to allow full use of the truck bed. The Double Lock comes with solid safety chain hookups, an attractive chrome trim ring, a durable A-coat finish and a limited lifetime warranty. This particular Double Lock gooseneck hitch is design to fit several models of Chevrolet, GMC, Dodge, Ram, Ford and Toyota (for a complete listing of vehicle and installation bracket compatibility, see application info).

Choosing the right gooseneck hitch is only half the battle in preparing your pickup truck for towing a gooseneck trailer. CURT gooseneck hitches are a premium option in the heavy-duty towing industry, but they are only one of the members in the heavyweight tag team that is CURT gooseneck towing. While a gooseneck hitch gets all the glory above the floor of your truck bed, gooseneck installation brackets provide sure footing and a solid foundation for that oversized gooseneck trailer. Gooseneck installation brackets work by bolting onto the frame of your truck, typically using pre-existing holes. With a set of brackets firmly bolted on, a gooseneck hitch is able to be attached and is given the strength it needs to manage the massive amount of weight of a gooseneck trailer. With so many gooseneck hitch options available from CURT, we wanted to make sure we offered the gooseneck installation products needed to give you a complete towing package. Our installation brackets fit multiple vehicles and hitch heads. This particular set of gooseneck installation brackets is designed to work with CURT Double Lock gooseneck hitches. It is rated to the vehicle’s maximum gross trailer weight capacity and provides a custom fit for certain years of the Chevrolet Silverado and GMC Sierra 2500HD or 3500 (see application info to verify fitment). 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 damages are not a problem.

These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper or trailer hitch.
