The Replacement Inner Slide for Demco DA91 Actuators # DM12808-97 replaces the inner slide for your Demco DA91 brake actuator and would allow you to use the Demco Trailer Coupler # DM14976-52 for a 2" coupler or the Demco Trailer Coupler # DM14040-52 for a 2-5/16" coupler.

The Slide Repair Kit for Demco Hydraulic Brake Actuators # DM5942 is the correct slide for your DA-91 if you are needing that.
