bigger tires... 4:10! simple as that.

If you need the 4.10 for increased tow rating or for taller tires then that is the way to go. If not, 3.73 is what you need.

 

I have 315/70 tires with the 3.73 and wish I had 4.10's. Even unloaded the accelleration is mediocre and you have to pump a gallon of diesel in the engine to get it to take off and it nearly lugs at flat unloaded highway speeds. Just do the math - if you like the way the truck drives with 3.73's and stock tires, get 4.10's. Going from a 265/70 to a 35" tire, will make 4.10's effective gear ratio like 3.70's. You will also get a little more drag from larger, heavier tires/wheels, and aggressive tread. If you're not happy with the 3.73's, then you have a lot of variables. I will regear some time soon to 4.10's.

 

seriously but for a 4x4 thats at least a $1000 thats why i opted the $50 for the 4.10's when ordering my truck up. cheaper that way. I have the 6 speed though too as someone mentioned and so i have ultimate control of the engine speed i operate in. right now 90 is putting the truck at redline. Not cool. but i did this because i am planning on going to 35's and wanted to keep everything copasthetic on my truck.
Plus i figure if i do ever want to tow heavy, heavy loads, i can always swap the smallish stockers back on... although if willwood or stillen ever get their 16", 15" rotor and caliper upgrade kits out, that wont be possible. But its great to tell myself i need bigger tires for gas mileage and cruising rpms! with the jeep everything had to be changed to fit the bigger tires, now i just need to change to bigger tires to fit the truck! happy days ahead!

 

I pull a 40 ft enclosed trailer from Minnesota to Montana 4-5 time a year and use it in Minnesota 6-8 time a year, If I where to stay in Minnesota I wouldnt need the 4:10 gears. In the bigger pulls in Montana I dont know how the people with 3:73 gears do It. I like to drive with the criuse set at 75 MPH and with the 4:10 in the mtns it rarely downshifts. I think the 4:10 with the bigger tire combo is the way to go.

 

Definitely 4.10s with the automatic.
