My 2000 2door LS 4x4 Blazer came with 31/10.50/15 tires
My 1999 4door LS 4x4 Blazer came with
235/75/15 tires
What's the difference in the factory set up of the 2 vehicles?
I read online.that for it to have 31's it has off-road suspension and then somewhere else it say zr-2's...
Mine has no factory badges or markings that indicate zr-2 or trailblazer package...
The RPO sticker is missing from both vehicles

 

The offroad package is the ZR2. Look on the rear of the front fender liners. If it is a ZR2 it will be in the rear of those two liners.

 

Unfortunately the p.o. cut the lower inners to fit the larger tires...
It has the fender flares but not sure if that's factory...
The rear leaves look more arched...
It has a different looking lower plastic under the front bumper....
I haven't been able to find any stamps or badges anywhere... I really need to identify this thing...

 

Get a VIN check, it will tell you if it is a ZR2 plus what gears you have in it. The stamp for the ZR2 on the inner fender well is up near the top.

 

Try something like this.

I looked at that link but it didn't provide what I need but thanks

 

If not that one, I'm sure there are others. That is what I did years ago. The nice part was I not only got the RPO codes but also their descriptions.

 

I believe the VIN plate in the engine bay will have ZR2 stamped on it if it has the Highrider/Higher-Wider package.

From your other active thread I think you may have found this.

 

I actually did thank you
