what is the best/most appropriate gears to run with 37s for maximum fuel economy without sacrificing ALL power and acceleration? 4.56's? 4.88?s

 

4.88s hands down

 

we have a winner^^

 

what kind of gas mileage can i expect to have with 4.88s and 37s?

 

its gunna be worse than what you get now!

 

i got 11.5 - 12.5 before the blower. And my mileage increased with big tires after the gear change. So if your running thirty seven s now with stock gears, expect you mileage to improve some after the gear change.

 

I get about the same mpg as efuehrin, without a blower, I'm running 37x13.5 D i c k Cepeks w/ 4.88 gears

 

another vote for the 4.88's

 

With 4.88s and 37s i get around 11-12 MPG.

 

With my 4.88's and 37"s, I get approx. 13 mpg highway,11 around town.I took my Edge out for the winter.That way I can't see just how much fuel goes to idling. It don't take long to get down to 4-5 mpg, when it's -30 and your truck needs ten minutes to get the chill out of it.

 

I've got 35s now and get about 15~16 mpg on the highway (65-70 mph) with stock 3.73 gears. is there any way to get that kind of mileage (or better?) with 37s depending on gears?

 

i get 16~17 mpg now with my stock tires, same gears. at 70 mph i am turning about 1900rpm. soon i am going to put 33's and i am hoping that the mpg will be the same or maybe a little better.

 

I highly doubt it.

 

I don't drive my truck hard on the road, I really do get 15-16 going about 66mph on the highway. I just wanna know what gears i need to get the best mpg with 37s
