It seems this question pops up quite a bit, but not all too often. I figured I would make a small post on it with pics, to show how I know my truck is a Zr2. If you know of another way to find out if its a Z or not, post up some pics and explain the differences.

The first way I know how to tell is the leaf spring hanger. The first picture is of my REGULAR 94' Sonoma. It is not a Zr2, this is how its spring hanger looks.
REGULAR s10 (Notice no fender flare too)

My ZR2 (Notice fender flare) Also how the hanger is built to hang lower, causing more lift on the truck.


The seond way to tell is to look behind your motor on the firewall. There is a white sticker with several codes at the bottom, My ZR2 has "ZR2" wrote on it, in this pic. (It may be harder to see if you dont have a body lift.)


The third way that I know is inside the front fender wells above / behind the tires. My truck has "ZR2" stamped upside down on these as well. You cant really see the pic, so I circled the area that this stamp is located.
Passenger side

Driver side


A fourth way to tell is how the flares attach to the body, the panels are different from a regular s10. This is how a ZR2 bedside looks if you remove the flare.


The fifth way to tell is by looking in your glove box at the sticker with all of your RPO codes. There are many 3 digit codes in here, just look for one that says "ZR2"


Now those are all the ways off the top of my head that I know. Like I said, If you know of ways, take pics and post up how you can tell. Pictures help explain things / locations better. Sticky? :) :tup:

I dont know about anyone else, but my 01 has ZR2 cast into the back of the transmission tailhousing. Remove the rear skid plate and look at the rear, passenger, lower corner of the transmission (looking toward the engine). The tailhousing of the transmission will have ZR2 cast into it.

Yea but I've seen some Bushwackers that look pretty darn close. Plus I'm sure its not too hard to mount Zr2 flares on a non Z. The flares can easily mislead someone to thinking its a zr2.
thats why i didnt even mention flares. i mentioned the harder ones to duplicate

The fender stamp will not always work. My 01 doesnt have them but everything checks out and the dealer decoded the VIN for me so its definately a ZR2.

Anyone else not have the fender stamps?

BTW, another way to tell is if you look on the driver door and the stock tire size is 31x10.50x15, you have a ZR2 or Highrider. Please correct me if Im wrong. I hate giving out bad info.

good call on the tire size in the door. thats prob another way.

and was yours maybe wrecked before? maybe they put reg s10 inners in? and my truck is the only Z ive ever looked that close at, so i dunno how common the stamps are.

YES!!!! Finally an answer. I was always under the impression my truck was a regular 4x4, but today as I was removing the upper intake manifold I noticed the firewall decal. It was quite dirty but I could clearly make out the "ZR2" in there. An yes the track bar is also in the rear.

Quick question though. Is the track bar supposed to be straight, or does it have a slight bend to it? The rear seems slightly slanted but I don't know why. All I know is that the previous owner flipped it onto its side, messed up the rear axle (fixed) and damaged the whole driver's side. Plus the front seems lower than the rear.

Isnt a 8.5 rear standard on a ZR2?
If so its easy to tell that rear end because of the fully round dif cover and the bulged axle tubes as it goes into the center dif.
