Zr2 optioned blazers have a different (stronger) frame, 8.625" rear differential, 3:73 gear ratio, 3" lift and 3.9" wider stance over regular 4x4, fender flares and skid plates. There may be a sticker on the driver's door that lists your tire size. If it says 31" tires you have a Zr2.

As mentioned, ZR2 uses a different frame, softer torsion bars, weaker rear leaf springs, wider track, higher stance, cast iron front differential, yada, yada, yada. Depends on what year, but the engine is either L35 RPO code, or LU3. Might want to think twice about the suspension lift: lots of ongoing expenses with steering linkage & suspension parts. Don't mean to tell you what to do with your truck, just pointing out that if front chassis ride height is out of spec, it will cause problems.

If you want an off road money pit, your best bet for something functional is SAS. Much easier and cheaper than trying to turn a non-ZR2 into a ZR2. Much more capable than a stock ZR2 if done correctly.
