if i install 2.73 on my car at 60mph will i make less RPMs if i drivin a 3:73 ?

 

yeah, it will make about 20-30 percent fewer rpm.
but it will not be as fast off the line.

 

Driving with numerically lower gears, yes. 3.73's are lower than 2.73's.

so my iroc is factory equipped with 2.73, os if i want ot put 3.42 in i would jus have to buy the gears and installation kit not a new carrier right?

 

2.73 and 3.42 have a different carrier.

you can get 3.42s and lower in the 2 series, i'd rather just get series 3 and add posi.
