Need New Gears

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.

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

what gears do you have now? 4:10 would work well...4:30 would be much better for towing, but higher RPM's

nice truck
