5th Wheel Hitch Adapter For Puck System of 2021 GMC Sierra


Do you guys have a 21 GM Puck adapter for my Reese 20k hitch? Part# 58293


Expert Reply:

We do indeed have an adapter that fits the factory puck system of your 2021 GMC Sierra (both the 2500 and 3500 long bed or short bed) that will allow you to use a standard 5th wheel hitch like your Reese. The correct part is the following:

- Adapter Rails for Curt 5th Wheel Hitch - Ford and Chevy/GMC Towing Prep Package # C88KR

And just a note, even though the title of the adapter says "for Curt 5th Wheel Hitch" it is compatible with any 5th wheel hitch that fits above-bed base rails, not just the Curt brand, so your Reese hitch will fit the Adapter Rails # C88KR perfectly.
