Paper tag on rear springs

I found a paper tag on the rear coil springs (96 Caprice) that says "TRZ 22076683", can anyone tell me what kind of spring it is? The SPID tag in the trunk says FE1 but it seems to sit high in the back and rides firmer than expected, doesn't seem like the soft-ride setup. Also, doesn't have any air shocks or anything like that. Thx.

the reason it is higher in the back is because the front springs are weak..

That's the part number on that tag I bet. Take it to gmpartsdirect.com and enter it as a part number to see what comes up.
