I have a 2024 Silverado 1500 TB with the 3.0 Duramax. I can’t find the build sheet that came with the truck and a trying to figure out the rear axle ratio. I’m guessing 3:23?
I thought 3.73 was only the 4 bangers with the 8 speed trans. Even max tow are only 3.42. Standard trucks with V8's and Diesel are 3.23. RPO code on my truck is GU5 for 3.23 ratio
It could be I was just guessing? The GM rpo code sticker for 2024 silverado is located on drivers side door pillar as a QR code sticker. Scan the QR code with your smartphone's camera to decode the RPO codes.
