#2016 of 2035 gearing

I would only say get the 4.10 gears if you are towing....
MPG shoudl favor the 3.73 since at highway speed the engine is at lower RPM....and should be using less fuel.,....also you will notice the sticker for both gears give the same MPG...and 2mpg gain is well a lot...over 10% on highway...Which can be due to anything.....
I have also heard the 4.10 gears are weaker since less material is available to transmit the tooth load due to having more teeth in the same diamter.....

...... Unless you have a big boat (21ft+) or camper and your going to tow with it every weekend, unless you live in an area with lot's of steep hills and valleys, unless your living waaay north of the Mason/Dixon line, then you should stay with the 3.73 .... what size motor are you lookin' at, you might only need a 3.50 ...

Dealer claims new motors perform better with higher rpm's looking at 5300 motor... probably trying to sell what he has in stock 4.10. I don't tow much at all .

the torque peak in the GM motors does occur at a relatively high rpm.

not much enough difference that if you do not tow will impact you too much in any way....unless you start modifying the engine for more Hp...then you may want to research which to get

...the salesperson has never owned a truck.
jdnbl,
The last thing you want is a V8 screaming at near-redline all the time just for "performance". In a truck, it's about low-end torque, not high-rpm horsepower. You have a lot of weight to get moving and, with the lousy aerodynamics, high speed will put unnecessary strain on the powertrain. Regardless of the redline and power numbers offered by the manufacturer, running higher rpms all the time will just wear out your engine, motor oil, and other components that much faster.
If you have a tachometer in your current vehicle, watch where it is most of the time. Then look to choose an engine that will be most efficient at that rpm range. I went with the diesel in my pickup because it gives me the torque and economy in the rpm range I drive (I never see the dark side of 2500 rpm - on the interstate, 70mph equates to just 2000 rpm). Now, I realize you can't get an Av-1500 with a diesel, but if it's just going to be a family hauler that makes an occasional trip to Home Depot, the 4.10 is likely not necessary.
The only reason to get 4.10 axles in a full-size truck is if you will
A- tow heavy things often
B- lift a 4x4 and add larger tires
If you just want to go faster, you probably should look at a smaller vehicle.

#2024 of 2035 Avalanche Satisfaction

Avalanche owners, how satisfied are you? I'm thinking of buying a used one, anything I need to be cautious of (01 vs 02). I'm also interested in the upcoming Nissan Titan and my waite a year for that.

AFAIK there have been no complaints or TSB's on 2001 models, so that might be you best bet.
On 2002 look for water intrusion around the midgate. Most don't leak, but those that do won't ever stop.
