Quietest gears? Yukon? Strange? Motive? Richmond?

Regardless of the brand on the box (Motive, Richmond, Yukon, Nitro, Hoosier, USA Standard etc...) all 8.75" gears are made in one of the following factories:

USA (1)
India (1)
S Korea (2)
Italy (1)

US/Strange is the only 8.75" ring and pinion always made by US Gear (USA).

BTW, USA Standard Gear is NOT US Gear!
