Custom hitches

A trailer hitch receiver is the starting point for most people looking to tow with their vehicle. CURT offers over 1,000 different custom hitch models to provide a perfect, factory-like fit on most vehicles on the road today. Our custom hitches provide a standard hitch receiver to mount a variety of towing accessories.

Vehicle-trailer wiring

The next step in equipping your vehicle for towing is to add a trailer wiring harness. Like our hitches, CURT custom wiring is made vehicle-specific for each make and model. Virtually all of our custom vehicle-trailer wiring harnesses install using existing factory connectors on the vehicle for a plug-and-play connection. No splicing necessary!

Ball mounts

With a custom trailer hitch receiver installed on your vehicle, a variety of ball mount options can be installed as needed. We offer loaded ball mounts with a trailer ball already torqued in place, as well as adjustable ball mounts, multi-ball mounts, tow hooks and more. A ball mount can be secured into the receiver using one of our hitch pins or hitch locks.

Cargo management

To add cargo space to your vehicle, CURT offers a number of cargo management accessories. Our cargo carriers are available in a convenient, use-as-needed hitch-mounted design, as well as a roof rack option. We also offer bike racks, cargo bags, cargo nets and ratchet straps for additional item security.

Product Description

Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 7-way round RV blade connector is designed to supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It features rust-free black plastic construction and comes with a spring-loaded cover to keep out dust and water. This 7-way round connector is a female-end socket, specifically designed for the vehicle side of the connection. 7-way RV blades are typically used on RV travel trailers, and this particular connector can be easily interchanges with other 7-way RV connectors.

    Cheap materials, could be better
    Feels cheap, is cheap.I needed something rather quick and didn't have time to spend searching for a better option.Yes, this is inexpensive but the plastic is thin and brittle, the wire clamps are thin and bend way to easily, and the middle wiring post is jank.My lift tab broke rather easily during installation before I even used it (see photo).This will get you out of a jam but I would not recommend this for someone that uses this connection a lot or really depends on this being rock solid for hauling trailers long distance.

    Reviewed in the United States on October 24, 2023
    I mounted this on my trailer (not vehicle as intended) to use as a “parking spot” for my trailer cable. The electrical contracts slow down oxidation on the trailer cable during trailer storage because they are connected instead of being exposed. It works perfectly. However it is all plastic (except the electrical contracts) and looks like it could break pretty easily. It’s perfect for my use but I would buy a sturdier one for my vehicle if I intended to use it for the vehicle connection. It will work but seems lightweight.
