Genuine Blazer ZR ????
 

I was wondering... how can you tell a genuine ZR2 from a fake?????

only 100% way is to check the rpo codes. other than that, the flairs are a pretty good indication. In the front, the should reach the entire way around the wheel well. There should be a small section of the flair that covers the bumper and valance.

RPO "ZR2" listed in the glove box lable, "ZR2" imprinted in the wheel wells up front, 8.5" or 8.625" rear end, and the flarelett as mentioned above.

I have done a lot of research on the ZR2, and just wanted to make sure I purchased what I researched.

Question??????
do all ZR2 come with a locker????????????

Yes and maybe no. The 4wd's did but I'm not sure if the handful of 2wd's made did or not.
