I have a 2000 and wonder if you can tell if your Blazer is a ZR2 thru the vin#??? Thanks in ADVANCE

 

I'm sure you can but a much easier way is to look at the sticker in the glove box and see if ZR2 is list in the RPO codes. Another easy way is "ZR2" is imprinted into the fender wells up front. One of them will probably be the mirror image.

 

There is also a sticker on the firewall behind the motor that says ZR2 on it.

 

You get one free trial, be very careful entering your VIN: Comprehensive Chevrolet, Saturn, GMC, Hummer, Cadillac, Buick, Oldsmobile, Pontiac, Geo, Dodge, Plymouth, Jeep, Chrysler, Ford, Lincoln, Mercury, Mazda Truck, Mercedes VIN Decoder

It will spit out a sheet with all of your RPO's, what each one means, and how many vehicles were produced with each of the RPO codes that are on your vehicle, cool stuff, print it out so you have it.
