I've had my 02 Z28 convertible for about 9 months now and just got around to deciphering the RPO codes on the door jamb. I found most of them, but could not find definitions for the following. AR9, K43, NC1, PW7, T82, VG6, V12, YA7, YF5, 1SB, I3Q, I3U, 19B, 19I, 4IT, 6bT, 7BT, 8TK, 9TK. I use the decoder on this link...http://camarossworld.com/Production%20Numbers/RPO.asp....but it appears it is not complete.

Also, I show code FE2 which decodes to SVS System, Ride Handling. Is this an option or do all Z28's have this? Sames goes with PW7 Limited Slip Differential. Is this an option or do all Z28's have this.

Thanks for the help, maybe somebody has another decoder I can use to decode the ones I didn't find.

 

I would hunt around and see if I couldn't find a year specific RPO code sheet.

Yes, all Z28's came with posi. differential. However there were a couple of different types, i.e. Auburn, Eaton, etc.
SVS is just GM speak for "shocks & springs". The FE2 is the standard Z28 (high performance) suspension. 1LE is the upgraded suspension.

I3Q, I3U, 19B, 19I, 4IT. Not sure about all, but are probably color codes. I know the 41T is black.

6bT, 7BT, 8TK, 9TK. Same here, probably suspension codes. Will say something like "computor selected shocks", computor selected springs".

 

If you look at this list:

http://www.marshu.com/ws6-firebird-c...codes-2000.php

AR9 - something to do with the seats
K43 - alternator
NC1 - CA emissions
PW7 - 16x8 aluminum wheels
T82 - auto headlights
VG6 - 5mph bumpers label
V12 - power steering cooler
YA7 - CA emissions
YF5 - CA emissions
1SB - option package #2
13Q - body side molding, sebring silver
13U - primary color, sebring silver
19B - black cloth seats
19I - interior trim black
41T - black top

I'm pretty sure the remaining four are the springs

 

And here's another one that includes the ones that are missing in the list above:

Awesome,

Thanks for all the help.
