After going thru the parts list pdf. I noticed that (EGX) is the code for normally aspirate vehicles, and code (EGZ) is for the SRT6.
Just thought I'd mention this little fact.

sway bar srt, looks like the same one as on Limited XF.

shocks srt; 5135 484AA and 5142 011AA.

srt axle; 5159 990AA.

srt rear rotors, 5135 475AA ;rear backing plate 5135 478AA and 5135 479AA.
