2019 GMC Sierra 3500 HD Towing Products

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.

Product Features:

• Mounts the Double Lock gooseneck hitch on specific pickup truck models
• Vehicle-specific design optimizes strength and installation time
• Constructed from high-strength steel
• Protected by a rust-resistant liquid A-coat
• Includes grade-8 mounting hardware
• Rated to vehicle’s maximum gross weight rating

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).

Product Features:

• Double locking pins for superior trailer and trailer ball security
• Flip-and-store ball keeps truck bed free of obstructions
• Removable chrome-plated 2-5/16″ trailer ball fits most gooseneck trailers
• Installation requires no welding or truck bed removal
• Heavy-duty handle can be positioned on either side of the vehicle
• Chrome-plated trim ring provides a finished look
• Rubber hole cover helps prevent corrosion in trailer ball hole
• Includes spring-loaded safety chain loops and grade-8 hardware
• Protected by a durable A-coat finish

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

Product Features:

• Carquest Premium electrical connectors meet or exceed OE wire gauge, insulation, and terminal material requirements.

There is nothing like the luxury and power that go along with heavy-duty towing. 5th wheel RVs offer a deluxe, home-away-from-home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, 5th wheels and goosenecks must be equipped with the proper lighting and electrical systems, and tend to require even more complex connectors than a standard receiver-type trailer setup. Make things simple with a CURT 5th wheel / gooseneck extension harness. 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. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your 5th wheel or gooseneck trailer. This CURT extension harness is designed to work with 7-way RV blade connectors and comes in a length of 10′. It is compatible with certain models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota (see application to verify fitment). When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, CURT gets you plugged in.

Product Features:

• Routes a 7-way RV blade socket into truck bed while retaining use of rear socket
• Simple plug-and-play design eliminates the need for cutting or splicing
• Allows for easy connection of 5th wheel or gooseneck wiring
• 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power
• 10′ extension with right-angle plug for easy installation
• Spring-loaded dust cover keeps connector clean when not in use
• Slit loom keeps wires contained and well protected

The CURT OEM puck system 5th wheel roller adapter for GM pickups combines the functionality of a CURT 5th wheel roller with the strength and convenience of GM’s truck bed puck system. The adapter is designed to securely mount a CURT 5th wheel roller and hitch head into the bed of your Chevy or GMC truck, using the OEM puck system. It is designed to fit the puck system in select model years of the Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD with 6.5-foot bed (see application info to verify fitment) (compatible with CURT 5th wheel hitches only). It features a set of adjustable, quarter-turn anchors to quickly and easily drop into the pucks and provide a moveable platform for the 5th wheel coupling point. It features a capacity of 20,000 lbs. and is compatible with most CURT 5th wheel heads (weight capacities are limited to the lowest-rated towing component). Like our OEM puck system 5th wheel legs, the key feature of the GM 5th wheel roller adapter is its quarter-turn anchors. With the hitch head and roller initially bolted onto the adapter, the adapter can easily be dropped into place whenever needed and secured with the quarter-turn anchors. The anchors can also be adjusted to help eliminate chucking noises between the adapter and under-bed platform while towing. When you are finished towing, simply turn the anchors to remove the entire assembly within seconds. The CURT 5th wheel roller adapter for select Chevrolet and GMC pickup trucks provides the ultimate in versatility for the CURT 5th wheel line. With a gross trailer weight capacity of 20,000 lbs., it is able to accept most CURT 5th wheel rollers, including the R16 and R20. It tested for safety in accordance with SAE J2638 and is coated in a highly durable carbide black powder coat finish to protect against scratches and rust.

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 USCAR connector and offers a 4-way flat and 6-way round connector (see application info to verify fitment with your vehicle). It also comes with a mounting bracket for easy installation. 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.

• Plugs into USCAR socket to provide 4-way and 6-way trailer wiring connectors
