Guys have a quick question for you were 3:73 gears an option on 05 Z71’s I thought 3:42’s were standard with an upgradable 4:10 gears.

the reason I ask I was told that an 05 Z I’m interested in has 3:73 gearing as per GM I don’t have the VIN but the guy I’m getting the vehicle from(friend) he comes across these vehicles a lot said he spoke to someone from Chevy and they told him it has 3:73 gears!

I could be wrong but I thought the only option other than standard 3:42’s for 05/06 were 4:10’s I’m hoping I’m wrong and it does have 3:73’s as good of shape thid vehicle is in I really preferred 3:73’s or better yet 4:10’s.

The rig is a southern rig fully loaded the tranny has been replaced and a new Jasper is being put in shortly the truck is coming from a trusted friend so mechanically I have no worries.

Just was curious if 3:73’s were an option in the 05’s

thanks

I'm not sure what was standard on the 05 Z71, but I do know that all of the ratios you listed were indeed available for those years. I used to own an 05 Tahoe LS and it was factory equipped with the RPO GT5 4:10's. In 05, you could have:
GU4 - 3:08
GU6 - 3:42
GT4 - 3:73
GT5 - 4:10
Have someone take a picture of the RPO sticker in the glovebox to know for sure what it's equipped with.

Ok thanks I knew for sure 3:42 was standard and 4:10’s were an option I did not think 3:73’s were an option!like mentioned however my friend did call GM gave them the vin and they told him it was equipped with 3:73’s so I’m sure that’s the case thanks
