4.10 gear question (GM or Motive)

[vtirocz]

I am looking to get 4.10 gears in my '00 Z28 M6. I have rounded it down to either GM gears or Motive gears. Which gears are more durable? Which gears tend to be quieter?

From what I've read so far, I haven't seen a difference between the two. Any feedback is appreciated!

Thanks,
Jim

durable = motive
quieter = GM

Any reason why you say the Motives are more durable?? Is the GM 4.10 gear a weak gear? I want the 4.10 ratio, but do not want an obnoxious whine on the highway.

Thanks,
Jim

softer metals in the GM gears.
