eBay & Marketplace can help!

Yup, and AXN axle is in the 'plans'... and a new front diff..
But I'm getting lazier everyday so who knows..

trying to convince myself to do my steering bushing today..
Let's see.. 7 nuts, a couple bolts, one oetiker clamp? .. I think I can, I think I can...

Was gonna say, I think I need a turbodiesel to overcome my 3.08 rearend!

Don't get me wrong. The off-idle strength of a turbodiesel is a very tempting siren song ...
but if you upgrade from 3.08 to 3.73 or 4.10, and have the shift table tuned to suit your taste,
I don't think you'd be disappointed. Same goes for the rest of you.

Stock tires, I'm sure I'll be ecstatic with the 3.46!
One day my tahoe will drive like all the other tahoes...

Part of me thinks they made the Z71 package just to use up all their leftover 3.08 gears..

Don't undersell yself - 3.73 and a good tune, you might not even want a 6.0L / 6.2L.
If it tows / hauls heavy, or plays hard, you'll prefer 4.10 for your 5.3L though.

Do groceries count for a heavy haul?

Thanks for correcting the gear ratio for me!

I can only do so much with my keyboard.
If you find a GMT900 with 3.42 (OE gear for suvs with a tow pack whose RPO escapes me) and take it for a test drive,
you'll see and feel why I suggest 3.73 or 4.10
(which GM gave OE to some pickup trucks with 6L80 / 6L90 and whatever tow pack option succeeded V4P).

In my GMT821 (Tahoe Z71), I itch very badly for a 6.0L and 4.10 with my 4L60E.

I might like 3.73's.. But I don't think I'm gonna (make my lady) spend for it.
Plus, she's gotta save up for that 10L80 and a motor once there's problems with either!

Another reason, I'm lazy. Swapping an axle and front diff is enough for me..

I don't doubt for a minute what you're saying..
But I'm hoping my expectations are low enough... Truck only has to be tolerable and reliable..
Hopefully I won't drive anything better to know what I'm missing!

3.73 will always be SO MUCH CHEAPER than a 10L80 rebuild OR a replacement direct injection V8, nevermind both.
especially if you find a 3.73 front diff to swap in.

If I fail to convince you, maybe I helped someone else out ...
