i have a dana 44 front axle and a 14 bolt rear. im putting 35s under it. the truck has 3:73s right now, and with the 35s would 4:10 be a bad idea. i would like to gear down a bit but it is a DD so nothing thats going to kill the gas
4.10s should b perfect with 35s
all i can say is 4.10s im doing sas and thats wat i have talk to kyle ask him how his is im pretty sure he is runnin 410s with 35s
i had 410 geared 3/4 ton's and 35's on my 89 k5 with a 350 tbi and a 700r4 and pulled 16+ mpg out if it

4.10s and 35s is a good combo IMO. i run em, i DD it, i tow stuff with em, dunes, mud, just about anything. work good for me ==thumbsup
You would probably get better mileage with 410's than you are with your 373's right now for the simple fact your motor would not have to work as hard to get up to speed. Our Bravada came stock with 373's I could not imagine running 373's with 35" tires that thing must accelerate like a turd.
there isn't that much difference between a 3.73 and a 4.10 it's one gear step, the 4.10 will do everythig a lil better than the 373 with those size tires though, the difference between the two at a crusing speed should only be about 150-200 rpm
