We do have adapters that will allow you to use your 5th wheel hitch in your 2018 GMC Sierra 2500 with the puck system, and the correct adapter is going to depend on if you have a short bed or a long bed (the pucks have slightly different spacing depending on the size of the bed).

- 6-1/2' Bed: Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package # DM6194

- 8' Bed: Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package # DM6206

These adapters will work with any 5th wheel hitch that fits standard, above-bed base rails, including your hitch from Curt.
