ZR2 has a wider frame too - thus the spring perches would have to be cut and moved inboard 2" per side.

You would need the ZR2 brake lines for the year of the axle as well!

S10 Warehouse on Ebay is awesome and that dude knows his stuff!

There are a few people selling G80s on Ebay rebuilt for $199.99. I know, it's where I got mine.

A ZR2 axle in a 4X4 Blazer would help to correct the wheel/track issues in appearance. Just know that you will be more inclined to clip curbs and what-not because the rear end always pulls a tight radius in a turn than the front.

My .02 and some change!

 

I do believe the frame is the same except the front control arms are longer, the lift comes from the rear lifts shackles on the front side of the rear and the axle tubes are 2 inches longer in each side i do believe it would of been to hard to widen the frame that little.

 

They have a different frame. which is why when you buy lift kits it asks if its a zr2 or not. That is the reason they sit higher. Not because they are factory lifted

 

Frame be different but not wider the spring pirches are 36 inches apart on both

 

The Question was is frame wider? Answer is still NO
