Did you recently rush to buy a new vehicle before tariff-related price hikes? A reporter is looking to speak with shoppers who felt pressure to act quickly due to expected cost increases; please reach out to PR@Edmunds.com for more details by 4/24.

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.

On 2002 look for water intrusion around the midgate. Most don't leak, but those that do won't ever stop.
First model year is 2002...and they were sold in 2001...
things to look for.....Tranny, transfer case electrical, Ignition switch, water leaks from midgate and fender seams......
these seem to be the items which give some problems......

I have the 3.42 in my 01 2WD Tahoe - wish I had the 3.73.
Next truck I buy will have the lower rear end gears.
Do the math - at 75 MPH with 3.73 gears your engine RPM will be about 2,083, with the 4.1's it is only 2,290. Yes that is 10 % faster - but still not - IMO - a high RPM level for these engines.
My advise - drive both - and get the one you like.
also we presently have two '01 burbans..both are 4x4..1500 series ... my wife's is an LT with 3.73 gears.. I have a Z71 with 4.10 gears... I get 10% less mileage on mine both in mixed city-road driving as well as over the road on trips... mileage comparison taken while I was driving in both trucks.. I usually drive either truck over the road on a trip.. let her sleep...
