Hey Gus! Yes, the Curt Front Mount Trailer Hitch # C52NR will fit your 2026 Sierra Denali with the Duramax engine. I noticed you had 2026 in the fitguide, it will fit the 2026 model as well if that is what you have.

What will you be using the hitch for?

I recall using an extra spacer washer on my 2020 GMC 2500 AT4. Also required my wife’s second set of hands, but install was fairly straightforward. Use it all the time for front mounted bike rack.
