Hi all,
I have researched this and it seems like 4.56 would be the way to go if I wanted to swap my gears as 4.77 seemed to have some reliability issues with a SC/TC. I'm doing the SoS ACed SC. I'll likely upgrade that for more boost at some point in the future...doing the base bolt on for now.

Is Hard Top Guy where I can get these? About how much did it cost you to install?
Thanks much!

 

gears having reliability issues? i think you need to research more...

 

I saw some posts back in 2008 that seemed to suggest 4.77s had to be replaced a couple of times at least. Maybe it was his driving. If no big deal, then great!

 

the thing about 4.77s is you are going to be shifting alot, NA.

if you are boosted AND have 4.77s, you are going to shifting even more.

 

Yeah, I saw that. Thanks for the info!

 

i had 4.57s and with 349whp it was fine!! However, now that im upping the boost to 11lbs (was at 7) I went back to 4.10 as I dont wanna be shifting too much.

 

Cool! Where did you get your 4.57s?

 

I never said how often I do that, lol.

 

high boost has the issue of BOOM! x_x
