Exactly what I was looking up.

Its not a body lift its suspension from the factory.

Are you sure about that? I was pretty sure it was a body lift...

As per wiki (not that wiki is always right...but):

The following factory-installed features are what made the ZR2 standout from other 4x4 trucks offered in the S-Series class.
Ladder Type Frame with Modified Mounting Points
100mm wider track (3.9 inches wider than regular S-10)
Increased Ground Clearance (Approx 3" over Regular S-Series 4x4)
Enhanced front (7.25" ring gear) and rear (8.5" ring gear) axles w/ 3.73:1 rear-axle ratio
Larger wheel and axle bearings
31 x 10.50" BFG A/T Tires (Pickup), 31 x 10.50" BFG Longtrails (Blazer)
Fender Flares
Spectra Gray on the Chevrolet Models, despite body color. Body color on all GMC Models.
46mm gas pressurized Bilstein Monotube shocks
Rear Track Bar (Pickup), Front Anti-Sway Bar (Blazer)
Skid Plates [1]
Front/Rear Disc brakes (1998-2005) , Disc/Drum brakes (1994-1997)
Full Size Spare Tire

To me that says body lift...but I could be wrong. I've been wrong in the past lol.

would this pose any problem if i wanted to but another 2" body lift on it?

Yes...If it is a stock 2" body lift (which I'm pretty sure it is) you wouldn't want another BL on there. That would be 4" of Body lift. Although it's been done before it's pushing what is safe and what isn't. I wouldn't recommend anything above 2" of body lift, even though they do make 3" BL kits I personally wouldn't feel safe putting one of those on.
You can get an extra 2" by putting new (bigger) shackles on for ~$60 and then cranking your tbars in the front for equal lift. Plenty of info around the forum for this method of lifting including lots of pics and tutorials, just do some reading.

Check your RPO codes in your glove box. It will say ZR2. Def looks to be a ZR2. Congrats!

Good to know! I appreciate the help here guys :icon_teeth:
