Curt Manufacturing 11037 Trailer Hitch 1-1/4" Receiver Class 1

CURT 11037 Class 1 Trailer Hitch

The CURT 11037 is a Class 1 trailer hitch with a 1-1/4 inch receiver tube designed for light-duty towing. It suits drivers who need a basic hitch for small trailers, bike racks or cargo carriers. Buyers who require a larger receiver opening for heavier accessories or weight-distribution systems cannot use this hitch. The black finish provides corrosion resistance for daily exposure.

Class 1 towing capacity limits

A Class 1 rating restricts gross trailer weight and tongue weight to the lowest standard category. The 1-1/4 inch receiver accepts only accessories built for that specific tube size. Adapters cannot increase the hitch's rated capacity or convert it to a Class 2 or higher rating. Installation must follow the vehicle manufacturer's specified mounting points and torque values.

1-1/4 inch receiver tube size

The receiver opening measures 1-1/4 inches square and determines every accessory that will fit this hitch. Ball mounts, bike racks and cargo carriers must match this exact dimension to install securely. No other receiver size is compatible with the 11037 model. Verify the receiver measurement before purchasing any add-on equipment.
