Question:

Can you share the dimensions of the hitch please.

Great question. Since the Curt hitch part # C36CR is a custom-fit hitch, it doesn’t have standard overall dimensions listed like a universal hitch would. It’s designed to bolt directly to specific trucks using factory mounting points, so the shape and size vary to match the frame of those vehicles rather than having one set of measurements.

On a 2026 Sierra 3500, most trucks come with a factory hitch already integrated, so when someone is looking at this hitch, it’s usually because they’re replacing an existing one or trying to work around something like a flatbed or aftermarket bumper. If that’s the case, I can definitely help make sure this will fit your setup or point you in the right direction.

If you’re trying to match something by size or looking for a more flexible option, I’d be happy to help you find a universal-style hitch as well. Just let me know what you’re working with.
