    whats the highest that came from the factory? i've got one out back that only turns a little over two revolutions with one tire revolution. maybe 2.30 or something? do i need a new carrier to switch to 4.56 gears?

    you can get a thick gear.... but that seems really shallow. dunno if they make em that thick.....

    from the factory i think the highest would be 3.73. open it up just to make sure whats in there.

    Are you sure the other tire wasn't rotating 2 turns in the OPPOSITE direction while you turned the one on YOUR side of the truck???!!!!

    Might be a lot more like 4.10s if that was the case, but really.....just pull the cover and read the stampings on the ring gear. We can help you decode them if you don't know what they mean.....plus that fluid is probably old and smelly anyhow!!!

    <font color="green"> I beleive that there are only 2 carriers for the 14b, so you would be able to use a thick gear to go to 4.56s even if it's got a higher ratio than 3.73. I've never heard of any ratio in the 2s for a 14b. </font>

    If you turn only one wheel and the other stays sationary while you count the pinion revolutions, then you need to multiply the count by two. So, you probably have 4.10 gears if you count was JUST over two rev's. If it was more like two and a quarter rev's, then ya got 4.56.

    I think if your turnin' one wheel and the other is going backwards, the pinion is probably not doing anything??? I donno??? But I do know that when I first bought my K5 and went to check the gear ratio, I jacked up only one side of the truck and I was wondering why it said I had a 1.54 ratio. Then someone clued me in on the multiply it by two part.

    Hmmm...Not to start an argument or anything, but I'm almost certain that the lowest ever available in a 14bFF was something like 3.23...3.2x anyways.I know that the 14b ff got 3.42's in alot of cases if they were in a diesel truck. Then 3.73, 4.10 etc etc. 2.73's I know were an option in 12 bolts. But in a 14b ff? /forums/images/graemlins/thinking.gif

    3:23 14BFF gears do exist. I looked at a 14BFF that was for sale by a guy here at work and it had 3:23's. Needless to say, I left it alone. /forums/images/graemlins/thumb.gif

    ok, so i took off the cover and the stampings say 41 10. using an old Jegs catalog i figured out they are 4.10. now what to do. ive got 33's(might go to 35) and 3.73 10 bolts in the truck now with a 700r4. i was going to go 4.56 in the 10's until i remembered about the 14blt in the backyard. should i just regear the front 10 to 4.10 and be done? i dont want to do it twice. what do you guys think

    your best bet would be to find a 3/4 ton 10 bolt or D44 with 4:10s already in there, After you get gears, and the Parts to convert your 10 bolt to 8 lug, you couldve prolly found a 8lug 44 or 10 with 4:10s for cheaper.

    i've considered that, but accually i want to run adapters on the 14 so i can keep my 6 lugs. if i decide to go that route,how much should i expect to pay for a decent 3/4 10 bolt?

    i dunno how prices are around there, personally its hard to say how much I would pay for a 3/4ton 10 bolt with 4:10s, im thinking like 150-250, but no more then 300... personally if i was selling a set of 3/4tons with 4:10s i would list it at 350 bucks..... all i can say is, Shop like a woman, keep looking for the best price.....
