i have a 2004 blazer 4X4. does it have a positraction limited slip differential? in the front and back? or just the back?i doknow that the rear ratio is 3.42 thanks

 

Its kinda unlikely since you have 3.42 gears. The blazers that came with the posi usually have 3.73s. The quick way to find out is to look in your glovebox at your RPO listing. Look for G80. If you dont see it, you dont have it.

If you wanna know more about the posi, search for G80 on here.

 

i just checked it. its got posi

 

Nice! Does yours work? Wanna trade for an open diff with 3.42s?

 

sorry, no thanks. it works, but i kinda need it because its already been in my blazer since the truck was brand new lol

 

Hahah ohhh well. If you change your mind, lemme know
