Gears & Axles - Quietest 3.73s for a 10 bolt ?

Are they the GM gears ?
And who sells these for a good price. I need to upgrade the crappy 3.23s....

Thanks

New Era sells AAM

Factory gear sets will be the quietest. The biggest factor in noise is how the gears are set up. Sometimes it takes more than one try to get it right.

i have motive 3.73 gears and mine are completely quiet

any gear shimmed properly will be quite

my motive 373s made no noise at all then they broke and my richmond 373s that is in it now don't make any noise and the 411s in my moser 9 inch don't make any noise
