Curt Manufacturing 11181 Trailer Hitch 1-1/4" Receiver Class 1

Curt Manufacturing 11181 Class 1 Receiver

This Curt Manufacturing 11181 trailer hitch provides a 1-1/4 inch receiver built to Class 1 specifications. It is designed for light-duty towing and accessory mounting on compatible vehicles. The black finish offers corrosion resistance for daily exposure. Vehicle-specific fitment must be confirmed before purchase.

Upgrading From No Hitch

Adding this hitch equips a vehicle that currently lacks a factory receiver for bike racks cargo carriers or small trailers. The jump is worth it when the vehicle structure accepts a Class 1 mounting point and the intended load stays within that rating. It does not serve buyers who need higher weight capacity or a larger receiver tube for heavier equipment.

Behaviour Under Continuous Towing

The Class 1 rating defines the maximum gross trailer weight and tongue weight the hitch can sustain during extended trips. Heat and stress accumulate steadily when the load approaches that limit over long distances. The receiver maintains structural integrity as long as the applied load remains within the published Class 1 parameters. Exceeding those limits voids the design margin and risks component fatigue.
