Curt Manufacturing 45023 Ball Mount Class 1 1-1/4 Inch Shank trailer accessory

Product Identity

The Curt Manufacturing 45023 is a Class 1 ball mount built for light-duty towing with a 1-1/4 inch shank. It suits drivers pulling small utility trailers, bike racks or cargo carriers behind passenger cars and crossovers. Buyers needing higher weight ratings or a 2 inch receiver shank should look elsewhere.

Shank Compatibility

The single specification that decides fitment is the 1-1/4 inch shank size, which matches Class 1 receiver tubes only. Verify your vehicle's receiver class before ordering because a Class 2 or larger tube will not accept this mount. The black finish resists corrosion during regular exposure to road salt and moisture.

Sustained Towing Behaviour

Under continuous highway loads the mount maintains a rigid connection between trailer and tow vehicle without developing play at the receiver interface. The fixed shank design eliminates moving parts that could wear during long trips. Heat from braking cycles dissipates through the solid steel body rather than concentrating at a joint.
