What gears?
So after doing some research (what i could find) it looks like i can swap my LS2 automatics 2.92 gears by going with an LT carrier and installing a 3.55 set.
Is there anyone making a 3.73 or 3.91 set for the LT automatic carrier? Really, really want 3.91s.

I don’t believe so. Isn’t Richmond the only company making 3.55s? I’ve seen a lot of complaints that those gears make a lot of noise. I don’t have the LS2 (RS that had 3.27s) but swapped in a 3.91 carriers, axles, and hubs from a 1LE. Absolutely love it and wouldn’t go back. Even with the supercharger that I just added.

Ive heard they were noisy but never any updates on if they grew quieter once they wore in.
My goal of running 3.91s might be dying.

I had both 3.73 and 3.91 in my 2012. The 3.91 felt better! Best bet is to try to find a used 1LE rear. Look on LKQonline.com

The 3.91 would be a good match for the 2013 L99 automatic set up?

I added them prior to my cam and TC upgrade. Definitely worth the upgrade and you'll notice a difference in the get up and go. With a big cam and high stall TC, it's hard to get traction and launch it.

I’ll also vouch for the 3.91s and put in a plug for the member in florida(?) that’s selling the entire 1LE cradle for a smoking price. Axles, better bushings, better suspension parts all in one! If I was to do it all over again, I’d seriously consider replacing the entire cradle. Much less work that swapping diffs, axles, bushings, etc.

If you can find a 1le rear that should have the stock 3.91 gears, go that route and save yourself the headaches i went thru.
