    I take off the diff covers just to make sure...
    My 14FF rear has the numbers stamped on the ring gear:
    41: 11 So thats 3.72727272 or 3:73's.

    I take a look at the Dana 60 front numbers that are stamped in the ring gear and it's like 48: 13
    Which is like 3.69230 gear ratio!?

    That would mean it's about a 0.0349 difference in gear ratio. Is this right?
    I know the 14bolts have like 4:10's and a Dana44 will have a 4.09 but that is .01 difference!?

    Whats up with that? /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/confused.gif
    Guess i should just order detroits and 4:56's for both and be done with it. /forums/images/graemlins/grin.gif

    yeah .30 difference is gonna hurt.


    what tire size are you going to? I am really looking to go to 4.88's before i go up to 42's but i may be stuck at 40's for a while /forums/images/graemlins/frown.gif /forums/images/graemlins/angryfire.gif

    Doh!
    I did the math in my head..
    now i sat down and wrote it on paper. ...It would only be a 0.0349 difference...

    I read somewhere that as long as its within .10 difference???
    Or was it .01 like the 4.10 and 4.09 gears?

    So i guess my question is do 3:73 (41:11) and 3:69 (48:13) gears match? /forums/images/graemlins/frown.gif /forums/images/graemlins/confused.gif

    I may keep 35's for a while but i suppose i'll go 37's down the road.
