Blazer 4WD rear end into a 2wd S10 question

Postby 94S10V8 » Tue Mar 06, 2012 1:00 pm

Hello all, I have just acquired a 4WD 1999 Blazer and was wondering if this rear end will swap into a 1994 S10 which is a 2WD. I have looked through the stickys and threads but have not found the answer. I was going to install a 8.8 in the truck to have a 3.73 / disc brake / posi rear end but this rear end has all these features without all the money or mods. Please advise.

The 4x4 rear is wider, but it will bolt in, :wink: 8)

I've done it... simply bolts in... perches line up perfectly and same pinion yoke.

IIRC, the magic number is 4" wider... 2" on each side... eliminating the need for 2" spacers if you plan on running a Corvette wheel... :thumbup:

If the 4x4 rear has disc-brakes, you're gonna havta modify your e-brake cables.

Thanks guys, I have a nice set of rims off a 3rd Generation Firebird which has a lot of backspacing compared to the rims I have on the S10 now.

Yes it can be done. I have the same thing on my blazer right now. And yes the number is 2 inches wider on each side.
