Ok I know the Zr2 is 7.25 ifs with 3.73 gearing and outback is 8.5 solid with 3.73 lol wow the same. But I was just wonder what is a 2000ish 4x4 blazer front is still 7.25? Rear I know is 7.5 solid, but what gear? 3.42? I've searched for this many different ways and found mixed answers so I thought I would just bit the bullet and ask the guys that know best.

 

mine are 3.42... there were several different options, 3.42, 3.73, 4.10 and maybe even as high as 3.08


im not sure about the front diff but i was reading a thread earlier today that said some of the non-ZR2 blazers did come with an 8.5 rear diff and that the most of the manual trans blazers have an iron front diff
