RPO = Regular Production Order

On my G6 the sticker is in the glove box. It will have a bunch of 3 digit codes on it. Each code stands for an item installed on the car from the Factory.

eg

On a thirdgen FBody (Camaro/Firebird)

L03 = low output 305 V8 with TBI ingection.
LB9 = Tune Port Ingected 305 V8
L98 = Tune Port 350 V8

GU5 = Axel Rear 3.23 Ratio
GU2 = Axel Rear 2.73 Ratio
FP3 = Ratio Transaxel Final Drive 2.73
NK4 = Steering Wheel Sport Leather W/Radio Controls
103 = Trim Combination, Leather Arctic White (93)

These are some examples I pulled from my Formula's decoder I got from thirdgen.org.

The RPO list is like a mini build sheet of a GM vehicle.

I do not know if the codes are all the same for different years. Wish I knew.

:cool:

If you go to a gm dealer they could look this up for you for no charge. If not, go to another dealer. Some sites will give you the number of cars built with certain rpo codes, but if you want to know what the rpo code option is, then i would just go the dealer.
