ZR2 vs Regular

I wanting to learn the mechanical differences between the ZR2 Blazers and my four door.  I know that they come stock with 31x10.5x15s and that they have wide stance cv axles.  They don't have the body lift so it must be suspension.  Does anybody know anymore?

Its been discussed before.  Comparing a regular 2dr Blazer and a ZR2 (never was a 4dr ZR2)...  The frame is completely different.  The rear diff is bigger.  Front suspension wider/heavier.  Just hitting the high points.  You can't just swap ZR2 front suspension components to a non-ZR2.

The rear diff is guaranteed to be an 8.5" or 8.625" on a ZR2, instead of a random chance on a automatic non-ZR2.
 
Wider frame, wider rear axle, wider front end, it sits higher...
 
Random chance of having the iron front diff in an automatic.

No chance of the iron front diff in the automatic.  It's only 5 speeds.

did a bunch of research, figured out everything I needed to know, thanks for all the advice, working on a 3in suspension, new pics up sooner than later!  Yeee Haaawwww!  

ummm HA!
