This was brought up in another post. I was under the long term understanding the higher numerical gears had more teeth on the ring, but smaller, therefore weren't as strong.

Another member gave me this info.

2.73s - 41 teeth on ring gear, 15 on pinion
3.23s - 42 teeth on ring gear, 13 on pinion
3.42s - 41 teeth on ring gear, 12 on pinion
3.73s - 41 teeth on ring gear, 11 on pinion
4.10s - 41 teeth on ring gear, 10 on pinion
4.11s - 37 teeth on ring gear, 9 on pinion <--
4.56s - 41 teeth on ring gear, 9 on pinion

He thought that they higher numerical gears were weaker because of the angle the teeth was different, thus making them weaker. Is that the correct reason, or is there something else which makes a lets say 4.10 weaker than the stock 3.42.

My first thought looking at this is that the 4.11 gear would be the strongest.

maybe the problem is that fewer teeth in the pinion causes slipping and cracking?

Gripenfelter

thinner teeth?

BPS

that's what I always thought but wouldn't fewer teeth imply thicker?

jpaugh

the pinion is thinner...
