This hitch is stringently tested in accordance with SAE J684 to ensure a weight carrying capacity of 3,500 lbs. GTW and 525 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. Once installed, the connector can also be conveniently mounted on the vehicle's trailer hitch receiver tube, using a CURT Easy-Mount connector bracket. The bracket mounts onto the trailer hitch with no drilling required, and its powder-coated steel construction provides a solid attachment point for plugging in the trailer wiring.
