Nice truck.

I don't know which RPO is which, but if you get the codes out of your glovebox (the little sticker with lots of 3-digit codes), others can confirm which you have.

I am not sure, but I think the RPO codes are not in the glove box on the newer trucks. I thought someone said that here at one time.

Now that would be a monumental change! They've been there for what? 60+ years? One of the best things about GM vehicles - knowing exactly how your vehicle left the factory.

I hope someone chimes in and knows for sure.

Post up a pic of the RPO sticker and someone will enlighten us.

Interesting - it looks like starting in 2018 they now put the top sticker on the driver’s side b pillar.

Also now it has a QR code that, when read, outputs your vin, year, and codes.

Here’s what came up for mine:

I just went through all of the codes, and though I'm 99% sure I just have z71 suspension, there's 1% that confuses me.

Here's the z71 code:
Z71 - Off-Road Package, includes Z71 Suspension, Z71 specific skid plates, Z71-specific (RCV) 18" wheels, (RBX) 18" all-terrain tires, Z71-specific grille design, (T3U) fog lamps, (BVV) Black tubular assist steps, (UD5) front and rear parking assist, (V76) black recovery hooks, Z71-specific front sill plates, (GU6) rear axle, (NQH) transfer case, Z71-specific rubber floor mats with logo, decal on cluster, badge on pillar and liftgate, (JHD) Hill decent control and (K47) High capacity air cleaner 1 - 4WD models only. Not available with (PDR) LT Signature Package or with any LPO wheels.

But then there are these codes near the end that confused me:
6ZK:
- COMPONENT FRT LH COMPUTER SEL SUSP (6ZK)
7US:
- COMPONENT FRT RH COMPUTER SEL SUP (7US)
8X2:
- COMPONENT RR LH NON-COMPUTER SEL SUSP
9X2:
- COMPONENT RR RH NON-COMPUTER SEL SUSP

Its just weird that they have front "computer sel susp" in the front only? But before that, the z71 code specifically says includes z71 suspension.

Can anyone decipher it for me?

Greetings to my fellow enthusiasts :headbang: I'm a bit of a car nerd, and I use forums all the time, so I figure it was high time to start helping others by putting my info and experiences out there. Hopefully it will help someone down the line like other's posts have helped me. Also...
