I 've got an 06 f-350 dually, i belive it has 4.10 gears in it, i was wondering if i can change them to something better for the long haul highway trips. I am getting around 13mpg and the truck revs high with the 4.10's so just wanted to see what to change too, and where i can get new gears from????? Thanks a lot.
You may try and contact Randy's Ring and Pinion or Yukon Gear and Axle. They may have what you are looking for. LT.
You can always go down to a 3:73. Someone has to make it. Or you can use an overdrive unit from Gear Vendor.
