Hey i just swapped from the 31's to 37's and yes as expected dropped gas mileage havent really noticed driving wise just in the wallet so i figure the best thing to regain that mileage is to swap gears. so currently truck is one in sign. and i want better gas mileage and not over geared let me know what you have done or what you tink is the best

4.10s are closest to stock over ratio. 4.30s are good if you are towing all the time. I'm putting in 4.10s with 38s hopefully when I get my tax return.

it depends on what u plan to do with the truck if ur going to be pulling go with atleast 4:30s if ure just goin to be driving it aroung 4:10s should be okay im goin to 38s and i pull alot so im goin to 4:56s also because the tires im getting are heavy

wel most shops charge anywhere from 250 to 400 just in labor per axle to change them out... gears with install kits varry but generally under 300 an axle... so about 1600-2k is what its going to cost to regear your truck
