Gears & Axles - Brand of Gears

A friend of mine suggested I pick up Richmond 4.10s when I do but I just read that they break kinda easy so what other brands are there and what does everyone else run I have a M6 i'm gonna go 4.10s when I change them out what brand seems to have the best quality stuff?

GM GEARS. I have 373's....no whine if installed correctly, and GM doesn't particularly want you to keep coming back with broken/shit stuff.

Strange or motive, I have heard more bad stuff about richmond then others. but focus more on the install then anything. good luck

Yeah I know where i'm getting them installed guy does great work and he perfers anything Chevy but 2 of my friend with stangs go to him, he just put gears in one of thems 04 GT and there is no wine or anything so im pretty confindent that he is gonna doa good job, I just didnt want them shattering down the rd
