So with the 3.73 axle ratio you can travel at a higher speed with better fuel economy but less pulling power (torque?) versus the 4.10/4.11 axle ratio would be the opposite?
Kind of like the difference between a passenger car and pick up truck?
Sorry for the redundent question x06col but I am was wondering the same thing myself.

Yep!
3.73 definitely delivers better fuel economy.
Yep! Lower torque but I don't take max GVWR loads anyway so that is not an issue.
Moreover, I don't need to "jack rabbit" from a dead start so the lower torque is again of no concern.
Additonally, the engine will be turning lower RPM's which reduces the wear factor too!
I believe I spoke with a GM owner/operator that had a 3.56 differential.
And yes, the col is correct that 3.73 would be referred to as higher.
My bad, but I was thinking in strictly numeric terms (4.11 being "higher" numerically than 3.73)and not in ratio factors.

Thanks for the follow-up info Rev. If your ever in east-central Indiana on the Lord's Day,
take exit #104 Greenfield, IN south to the first traffic light, turn left ( you'll see a Walmart),
go about a mile (thru a 4-way stop) to Brandywine Community Church. We have 9:00AM & 10:45AM services that will Bless your socks off.

Dear Brother Batman,
I thank you for the kind words and the invite.
If I am ever on the Indy board waiting to drop off on a Monday, I'll try to stop by and visit.
I only live about an hour and half away in the Dayton area, so I will always be drawn to my home church, but as we all know expediting is prone to change our plans with a beep from the QC.
Again, I thank you for courtesy. Please let me know if I can ever be of assistance to you and yours.
