Each CURT class 3 hitch is engineered to fit on a specific vehicle. This provides the best possible fit and easiest installation. This particular custom class 3 hitch fits specific years of the Subaru Outback (to verify vehicle compatibility, see the CURT application guide or use the Vehicle Lookup tool). It is designed to integrate with the vehicle's existing features and offer a reliable connection to your trailer. This Subaru Outback hitch is stringently tested in accordance with SAE J684 to ensure a weight carrying capacity of 4,000 lbs. GTW and 600 lbs. TW. It also features a 2" receiver tube opening to accept ball mount or other hitch accessory with a 2" x 2" shank. CURT custom wiring provides everything you need to connect your vehicle's electrical system to a trailer. With a plug-and-play connector, a custom wiring connector easily integrates with your vehicle to provide a standard trailer wiring connector, typically in the form of a 4-way flat. To complete this custom wiring connector, it comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use.
