RPO code sticker.JPG


I have some codes I couldn't find explanation for:

1. EVA.. something to do with emissions and the evap system?

2. R6Y..I found nothing

3. SLL...I found nothing

4. 6XB and 7XB... something about computerized suspension? :confused:

What is "special heavy trailering equipment"?

Thanks for any clarification.

EVA = TEST DVT, EVAP EMISSION REQUIREMENT EVAP EMISSIONS REQUIRED(EVA)

R6Y = CONTROL, SALES ITEM NO. 24 (the only reference I was able to find)

SLL = SOLD ORDERS SOLD ORDER(SLL)

I believe a computer program or algorithm is used to select spring rate, height, etc. using vehicle weight, equipment and options combos :shrug:
6XB = COMPONENT FRT LH COMPUTER SEL SUSP (6XB) SUSP(6XB)
7XB = COMPONENT FRT RH COMPUTER SEL SUSP (7XB) SUSP(7XB)

This is the only reference I've found to "special heavy trailering equipment". I think it means that there's mounting points for a Reese hitch.
Z82 = TRAILERING PACKAGE(SPECIAL)(REESE TYPE HITCH) PROVISION FOR HD TRAILER EQUIP(Z82)
