Hey William! It looks like the GVWR of your 2024 Brinkley Model Z 3100 is 14,995 lbs. Are you looking for the standard king pin? If so, the correct pin box is the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY78GR. If you want the gooseneck pin box you need the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY33GR.
