today i was on my way somewhere and the rear end blows does any 1 know wat gear settings are in a 99 lt 4 dr 4wd blazer? and what kinda of limited slip i should put in it?

 

you will have to check your rpo codes for your gear ratio. They should be in your glove box.

GU4=3.08
GU5=3.23
GU6=3.42
GT4=3.73
GT5=4.10
HC4=4.56

G80 - locking differential

 

yea i have gu6 or 3.42 but i want a locking or limited slip is there a cheep but good place to get them?

 

ok oso i went to the junk yard and pulled out a bravda rear and its a g80 and will this affect any thing w/ my 4wd?

 

So long as it has the same gear ratio as your current rear end, it should be a direct swap.

 

yea so now i have a rear thats 11.41 and mine is a 12.41 so i won't be able to use 4wd so im just selling it now any 1 need it? its also a posi

 

Neither of those is an S-series gear ratio...

 

i no it say's that on the big ring gear witch means its a 3.42 and a 3.73 rears

 

If you have verified that both carriers are equivalent (ie. that the other one will fit), then you can swap the gears onto the replacement diff and then go through the proper setup of your diff.

 

If it came out of a second gen Bravada, you should be able to swap the gears straight across...
