Custom hitchesA 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 wiringThe 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 mountsWith 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 managementTo 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. |
