I just changed diff and t case fluids over the weekend and noticed the bright yellow blisteins on my 2dr 2000 blazer. I did some research and found the ZM6 code in the RPO codes.

Currently running open country toyo h/t 235/75r15 tires on stock rims
Was looking up what id need to run 31s before i knew about the rpo code, and now from what ive seen im able to run 31s with slight rubbing.
I dont know how the 18 year old shock ride height holds up, or if anyone has done this successfully.
Let me know if 31s will fit on the zm6 blistein setup.

These threads might interest you. FWIW, shocks have nothing to do with ride height. That is controlled by the springs.

 

Yeah ive come across both of these threads but they dont mention anything about the zm6 ride height or possibility of 31s.. thanks anyway though

 

The first link, second post discusses 31" tires and the fact that they will have minor rubbing without a lift. ZM6 ride height should be the same as stock.
