Question Which Gear is Quiter??

I am going to swap my 3.23 gears out of my 10 bolt for some 3.73's and I want to know which are the quietest??

Help me out guys!!

Plus if you could chime in with the best place to get a good deal on them, I would be very grateful!

I have 4.10 GM AAM which we put in just last weekend....can't hear a thing. Of course you have to make sure they set up correctly. From what I read on here, Richmonds are the most likely to be noisy.

Don't rule out Yukon gears. I have been installing those for a while now and even with ratio's as deep as 4.56, they are still quiet.

AAM gears (OEM) require a VERY tight backlash and WILL make noise if not set up correctly.

Yesterday I installed a set of MOTIVE 4.10 gears for a guy on performancetrucks, and with the windows up, AC off, and radio off, there was NO noise.

It all depends on how gears are set up. I have had successful results from Yukon, Richmond, Genuine, and Motive gears.

Almost all the time the factory option will be the quietest. It may not be the stongest but its usually the quietest.

Which Gear is Quiter??
Simply stated... The one that is set-up correctly.

Also dont rule out USGear and Percision Gear. Besides the OEM and AAM gear sets, I have had the best of luck with them. 'Performance' Motive gear sets are also a good cohice.

ive said this to people too many times ....the brand of gear has nothing to do with noise...its the tech installin the gear....
if yourgears are noisy somthing is off....usually loose clearances or
not enough bearing preload...unless a gear is straight cut it is not supposed to make noise....

Any AAM made gear will be the quietest. AAM makes them for GM I am 99% sure.

It is also the nickel content in the Richmonds which make them louder.

It is the Tech installing them that makes them quiet!!

I have to say Of all the gears we sell AAM comes back the least. Motive Gears have gotten alot better in the last few years.

AAM does make the gears for Gm and now Dodge.
