just like it says is there much differance between 3.42 and 3.73? I have 3.42 and can get a good deal on some oem 3.73

 

meh its not worth the trouble IMO. Go 4.10s if anything.

 

Yup yup... And buy some good aftermarket gears...

 

yeah go 4.10s my 3.73s arent much diff.

 

okay who makes good gears?

 

Yukons would be what I would get(what I am running along with half the site)

 

okay thanks ,read my new post please

 

around .31

Dont waste your time get some yukon 4.10's

 

im gonna get the 4.10

 

AAM 4.10 gears are the best money can buy. The best part about it is they only cost $10-20 more than Yukon's. So, I really see no reason why anyone would buy anything other than AAM's unless your getting a ratio that they dont make for factory vehicles. They're heat treated to 1500 degrees from the factory....so their essentially broken in already.
