What is the different between Z51 Shock Absorber and Non Z51 ??

Z51 shocks were Bilstein/Delco, the base stuff was Delco. And yeah, Z51 was stiffer.

Thanks!
and our ZR 1990 has Z51 shocks, or Non?

No, the ZR-1 came with FX3 shocks, the adjustable ones. Z51 was a non-adjustable suspension.

1990 cars do have the Z51 RPO, though. But apparently it didn't include the suspension pieces when coupled with RPO FX3. I think about all we got from it is the power steering cooler, as the ZR-1 doesn't have the faster ratio steering either.
