Does the Curt 5th Wheel Rail Kit fit a 2018 GMC Sierra 3500 Dually?  


Can Curt fifth Wheel Rail Kit work on a GMC 2018 3500HD Dually


Expert Reply:

Yes, it will. The Curt Custom 5th Wheel Installation Kit item # C16411-204 is confirmed to fit the 2018 Sierra 3500 dually. It fits both the 6-1/2' and 8' bed lengths.

To make towing with a 5th wheel easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C56000. This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel trailer easier and more convenient.
