Updated 01/13/2026 | Published 01/12/2026

Question:

Can someone confirm that item number DM6166 will fit part DM88XR? I aske because the 2 appears to have a curved shape where bolts mount where the 2 5/16 models are flat.

Hey Richard, yes the hardware kit part # DM6166 is correct hardware kit for the Demco Trailer Coupler # DM88XR. That curve shape in the corners of the coupler are compensated for with the hole design in the coupler. Do you have the channel already welded to your trailer frame.
