1998 5.7 3500 LB-CC SRW

Could someone help me find out what the following RPO codes refer to? I pull a 7500 lb trailer and want to know I'm doing what I should to cover the stress I put on it every summer. I found the most important codes GT5 4.10 rear axle, G80 Posi, KNP heavy duty transmission cooling system. The chart doesn't list the following.

 

R9A

R9V

SLM

VXS

ZQ3

1SA

1SZ

6XD

7XD

 

in addition what does the following refer to?

 

168.5 C030943

BC/CC U 8624 13V

 

Any help is greatly appreciated!

I can help with a few:

 

SLM - is a stock ordering code (how it is ordered and built not equipment)

 

1SA and 1SZ - are package option codes (i.e. when the vehicle order was put together some of the equipment options came as part of a package)

 

VXS - means a complete vehicle (non-completes go to places that add ambulance and RV bodies and the like)

 

ZQ3 - driver convenience package (tilt steering and cruise I believe)

 

6XD, 7XD - spring rate codes (computer selected)

 

R9A and R9V - some kind of sales codes

 

C030943 - specific model # for 1 ton, 2WD, long bed, CC, etc

 

Some of the others are paint (BC/CC U 8624) and interior colour codes

Thanks! Rob. Once I started looking these up I had to find the answer to the missing ones, I'm goofy like that.
