gears
so im thinking about going in and re gearing my truck. right now its got the stock 3.73 spinning 37" tires and my fuel economy sucks. from what ive heard talking to people if i went to a 4.10 then it would be like running the stock tires on the stock gears
so i wanted to get yalls opinions bc im gettin 16 mpg and hae heard that getting the gears back to normal (with my tuning) i could get up into the high teens or low 20s
any info on this would be amazing.
thanks

OP....The "new" ones--2011, maybe 2010 even--are running 3.31 ratio with the diesel/Torqshift combo.
3.73 is a good gear. 4.10-4.30 gets to be too much with the older truck's transmission ratios.
16mpg out of a 7.3 extra cab with 37's isn't too bad at all actually. Those trucks aren't economy queens.

I talked with Dale @ Tymar and we were running some ratio configurations...
I am running a 35" tire w/3.73's which calculates to running 3.31 gears, which pulling a 35' 5'er isn't ideal...
I would have to go to a 4.10 gear w/35" tires which calculates out to like a 3.77 or something like that.
Just my 2 cents!

Well I dont have the 3.73's anymore... I thought I would be smart and when I blew up the rear end step up... Wish I had not.
Most of my towing was done above 65 mph...
Here is from about 15mph to about 50mph with the 3.73's and about 25k in tow...
And another up in the mountians following Chelseas X with a trailer in tow... Dont laugh at the music, just what was on the radio...LOL
