Default 410 or 411 gears ?

Gentlemen,

I'm considering upgrading my m6 car gears. I've read a lot that upgrade to 410's, some others mention 411's. Is this accurate, that both are available for f-bodies, and if so is 410 better than 411 or vice a versa ?

My car came with 4.10's upon purchase, and with a M6 running a heads and cam setup its the perfect gear IMO

OK, is there any appreciable difference from 410 to 411, such as better quality gear, etc ?

I've heard the 4 11 is a tiny bit stronger, but nothing worth speaking of

Look at it this way. 4.10 is 41 x 10. 4.11 is 37x9. So the teeth on the 4.11 are approx 10% thicker. Therefore, slightly stronger

Yup. And the surface on them is so small for a ten bolt. Really I'd stick with 3.9 on a ten bolt. Those are stronger than the 4-series

Your splitting hairs here. They both suck in a 10 bolt. Find a used 12 bolt with the gears you want and a true trac possi. A lot will say it's too expensive but if you beat your car, you will end up there anyway. $500 on gears makes no sense in a rear end that's just gonna take a ****. 12 bolts can be had for around $1500.
