2013 Sierra HD, is a gear change worth it?
Hi everyone, I'm new to this forum and have a question about my 2013 Sierra 2500 HD with a 6.0L and 3.73 gear ratio. It has a tow rating of 9400 lbs and in the manual it says if I had 4.10 it goes...

I'd stick with the 3.73, as you have a "modern" 6-speed gearbox.
IF you ever go to a larger, heavier trailer you can always consider deeper gearing at that point.
If you had the older 4-speed, I'd have recommended the gear change. I went from 3.73 to 4.30 in my 2008 5.4L gas F250 (heavy truck, XLT crew cab 4x4) and it made a great deal of difference.
I think gearing swaps are very vehicle-specific, and my heavy truck with a small-block gas engine benefitted greatly. In other cases it's a waste of money.
