are they both the same height stock? im talking about the non zr2 4x4 blazer vs. the 4x2

As far as I know they are about the same height stock. But not totally sure.

the ZR2 is wider and higher

I knew that, but he was asking between a regular 4x4 (non ZR2 packaged) and 4x2

At least for the 2002's, the Chevy catalog lists the heights as:
2WD 4WD
2dr. 64.9" 2dr. 64.5"
4dr. 64.3 4dr. 64.2"

Yeah, it seems strange that the 4x4 shows to be slightly lower, but that's how they show it.

thanks guys big ups

Probably a little extra weight making it sink down a bit...
