RPO Codes: One oddball in my list
This question may be posted somewhere around, but I didn't see it in my searches:
A few days ago I was watching a video linked from here regarding the G80 RPO Code indicating the Eaton Locking Rear Differential. I got curious and started looking up all my RPO Codes for fun. I've got a 2007 Silverado 1500. All my RPO codes seemed right / fine with the exception of "1LT". I have no idea what this one is, and I've only seen it noted on Malibu codes as the LT-I trim package. I've checked the sticker, it's not a wrong note on my end that I can see. I still have the original window sticker, and it's an LT-II Package on there.
Anyone have any ideas on the "1LT" RPO Code? If not, it's no big deal, I was just wanting a complete list for fun.
I'm using these two sites for my lookups:
Thanks all!*Insert witty signature here*

Technically, since your truck is the LT2 pacakge, you have to thave the LT1 before you get to the LT2 package. As in, the LT1 has everything the LT2 has plus whatever extra options make it an LT2. Hence, they put both codes on the sticker. I have nothing to base this on; I'm just thinking out loud.Clint (TX) 2001 Silverado LS 4.8L auto 2wd ECSB [GARAGE]

The 1LT code makes sense to me, the LT-II does not. All RPO codes are only 3 char/dig long and do not have any -
I suspect the LT-II is a marketing/salesman code and not a build code. You need to figure out what comes in the LT-! package and then what is added by the LT-II package. Then you can probably answer your question.Ray

Just go to http://www.compnine.com/vid.php and do the free 24 hour demo. You put your vin in and they list all the RPO codes and explanations. I did it and then copy and pasted them into a word document and saved it so I will always have it. It will list everything from alternator to tire size

The link Pikey provided is a nice one but be sure to copy/past like he said, the first time you use it. As far as I can tell, if you try to use it again, it wants you to pay for the info and won't show you anything until you do.

Yes, the 1LT RPO Code is directly from the glove box sticker

Pikey, Just went to the link for decoding, and it is no longer free for the total decode. you enter you vin, they confirm they found it, and the actual build date, but don't show the codes without payment.Las Vegas, NV...2001 Silverado 1500 LT Z71 Stepside X-cab, 171,000 miles, 5.3, cat-back duals, leveling kit, 3.73, 17" rims, more to come...

That stinks. I used it last month and got the free demo. It used to be completely free.
