Gear ratio

Oh cool, well that gives me hope lol. I'm almost to 100k. Hope mine is good to 200k haha.

4.10 was available from the factory. Look at your RPO sheet (in your glove box) to see what gear ration you actually have:

GT4 Rear axle, 3.73 ratio
GT5 Rear axle, 4.10 ratio
GU5 Rear axle, 3.23 ratio
GU6 Rear axle, 3.42 ratio

Hi, how can I check my ride rear axle? It is a Tahoe 5.3 LT ('01 MY) but its sticker does not show those acronyms mentioned in the post quoted below. Thank you.

Sorry to hijack, but Is this the sticker you are talking about? I'm sure my Z71 came with 3.73's, but just thought I would check....View attachment 160438

Yes that is the sticker. You have the GT4 (3.73)

You can also contact GM with your VIN and ask for a build sheet they will gladly give you one that’s what I’ve done a few times before going to look at a vehicle just to see what they were equipped with coming out of the factory.

you can email them as well

Thank you for your gently reply

Is this "build sheet" for free or for payment? Does it show precise production date too?

Thank you.

No lol, there aren't 4.10 ratio grears in it from the Factory. My 2001 has a Tow package and I it came with like 3.23's She has 4.10's now and man will she get up and go or pull a Boat or U-hual with ease. but the fuel Consumshion is Very Bad too. I belive there where two Gear Ratios that You could get from the Factory with the Tow Package.

waiting on ( The Hoe ) to Chime in or ( Jenn Bear )

You are actually wrong on that. My bro has an 03 Tahoe z71 with 4.10s from the factory. Look at the glove box with the codes. If it says gt5 that means it has 4.10s. gt4 is 3.73.
