Whoever set those gears up did a good job. Nice contact pattern in both directions.
I wouldn't use it a poster pic for Amsoil though. I've seen plenty of clean diffs with just as many hard miles running store-brand oil. The cleanest are the ones with no limited slip clutches, but the 3.73 LS in my F-250 was pretty nice looking running the O'Reilly's synthetic lube with their friction modifier.
The worst looking diffs are the ones that get water in them because the vent tube gets pulled off for some reason or another...
I know that is not enough miles to prove anything but I was showing the people that said I would ruin my running gear towing that heavy with the 3:42's. I wish I had a pic of my 98 with 300K using AMZ/OIL the gears looked very nice!
Closer pic. I still think it looks pretty darn good Fish!
