Unexplained RPO Codes

[cbgrant74]

My 2015 LTZ crew cab has been built and is being shipped. I got a copy of the build sheet and most of the RPO codes make sense. I can't figure out a few of them, though. Does anyone know what these actually mean?

 

XL7 FREQUENCY RATING 315 MH

X88 CHEVROLET CONVERSION

VRK VAA/COMPONENT REL ROOF TRIM

YE9 TRIM PACKAGE

7D4 COMPONENT FRT RH COMPUTER

9X2 COMPONENT RR RH NON-COMPUTER

6D4 COMPONENT FRT LH COMPUTER

8X2 COMPONENT RR LH NON-COMPUTER

 

Thanks.

They are all described correctly. The component ones are the spring rate codes (springs are computer selected based on wheels, tires, suspension code). YE9 is luxury trim package (uplevel door panels vs. WT/LS panels). X88 signifies Chevrolet. XL7 is the frequency for keyless and TPMS. VRK I'm not sure. Possibly signifying that it has roof ditch moldings and the code represents the cab config?

Came across this list of RPO codes on another forum.

 

Obviously they are not all orderable' codes, and they don't all apply to a pickups, but it gives and ideas of how many there are.
