Gear Ratio RPO code? HELP!
just bought myself an 05 Sierra 1500 z71 95k. Still smells new btw.
I hooked up my programmer out of my old 2500 and went to set the tire size/ gear ratoio and it started my gear ratio out at 4.11 and If I remember correctly it started out on my 2500 at 3.73. So I'm wondering if in fact it does have 4.11s. I know you'd have to of special ordered one or by the grace of god had a dealer smart enough to order it with 4.11's.
So, Which RPO code tells me my gear ratio?
