    I pulled the diff cover on my truck and it is 2.73. i have never seen a 2.73 in a truck. i counted it 3 or 4 time and it the same every time. now i know why i have to put it in low almost all the time i went wheelin. it is a 83 truck with 700r4/208. supposedly its a heavy half, but with 2.73 gears....has any one else seen what i have. one good thing is i could go fast and smoke my tires fast. i had my truck up to 100... i think (only have 85 speedo and it was pointing straight down)

    I've heard of those gears, but at least I've never heard of them in a 4x4, but it's possible. That sucks, because if you want to change gears, you need to switch out carriers... I've had mine to 100 too...
