Trailer Hitch that Fits 2021 Mercedes GLS450
Updated 10/30/2025 | Published 02/04/2025
Question:
I have a 2021 GLS 450 which didn’t have a factory installed hitch. Is there any difference, except for cosmetic, between the Curt and the stealth packages? It seems that the curt has more “take” on the frame than the stealth, but I see great reviews of the stealth as well! Also, my installer told me that with the Stealth packages car won’t need reprogramming for the hitch. Is it true? Thank you

Hey George, for your 2021 Mercedes GLS we only have an EcoHitch part # EH55SR which is a really cool design but I would say that it looks like it has more brackets and gussets than similar Curt hitches. It also really cool that the hitch opening is removable for a totally invisible look. Do you need wiring too? What will you be doing with the hitch?
