Can someone tell me what spacer this is?

I bought a used TRD Sport about a month ago and the previous owner claimed it had a 3" spacer lift. After putting on some 285/65/18's, there's some pretty significant rubbing.

I am planning on a coilover lift soon, but in the meantime would like to know what i'm working with.

Can anyone tell me what this is?

 

It's an in coil spacer lift. Looks like stock shocks and coils.

 

^ What he said. I think Toytec and some other companies etches theirs. Otherwise it's a basic spacer. Stock coils and shocks. Coils could be sagging as well.
