If Corvette made a zr1 and blazermade the zr2 and also the zr5 4dr s-10.... Who made a zr3 or zr4 on any model vehicle???

 

one would infact wonder what the zr 3 and zr4 are

 

Well...they're not so much 'body styles'....they're suspension packages.

ZR5 is the sport suspension for the trucks, ZR2 is the offroad suspension package for the blazer, Not sure if ZR1 is actually a suspension package or just a naming thing...

BUT...from previous research (see THIS thread), the ZR4 sticker has been used before, but by American Luxury Coach on a custom 5.3L Silverado with Supercharger and body kit and what not. ZR3 may have been never been used...

Also remember the fullsize trucks with the Z71 suspension, Z85 on the Colorado/Canyon

I still wanna put a ZR4 sticker on my blazer
