Curt Double Lock, Flip and Store Underbed Gooseneck Hitch and Accessories For a 2018 GMC 3500 Denali


I have installed over 8 Curt Gooseneck hitches and love them. Just need to verify the subkit needed. I have in stock from you a 60607 Gooseneck Hitch. Will this work for this application using the Subkit # 60604 Curt 600? Other than a in bed wire kit, anything more I need for this install? Thanks

Yes, the Center Section # C60607 will bolt to the Curt 600 Series Gooseneck Installation Kit # C60604 and fit your 2018 GMC Sierra 3500HD Denali Diesel. We have both parts listed as the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch # C607-604.

The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 and some White Grease Hitch Ball Lube # 58117 are the other two things that come to mind for Gooseneck towing.

If they are possibly going to 5th wheel tow a Curt X5 5th Wheel Base Rails Adapter # C16210 with a 5th wheel hitch like the Curt A20 5th Wheel Trailer Hitch # C16140.
