Been folloewing the rear gear talk for years and am still confised. Can some one enlighten me.


1 - who makes 4.11 gears - where to buy?

2. are 4.11 stronger than 4.10?

3. if the more teeth the weaker the gear then are 3.42's weaker than 4.11 based on the facts below?

3.42s - 41 teeth on ring gear, 12 on pinion
4.11s - 37 teeth on ring gear, 9 on pinion <--

if not why?



Confused in Canada

 

If you compared the two pinons side by side, the 9 tooth would be a smaller diameter. That is why a two series carrier has the ring gear mount offset father from the pinion, 2.73 has a large pinion diameter

 

What Steve above said.One pertains to Ford and the GM. You can call them what you want. I belive, don't qoute my on this but, GM=4.11's and ford=4.10's. I always called them 4.10's

I just swiched over to a currie 9", and by doing that did not have the option of running 3.73's any more. They are 3.70's now, but I still call them 3.73's. Hope this all makes since???

Of course I could be wrong altogether.

Just my 2 cents.
