    I would suggest at least 4.10's since it would appear you plan to off road it a good deal. If you want better power for off road 4.56 is the best bet imho. if you go to a junkyard you will have to count the ring and pinion gears' teeth. Divide the ring count by the pinion count to get the gear ratio. Example; 41 ring teeth and 11 pinion teeth 41 divide by 11 is 3.73's :waytogo:

    would also depend on tire height and if you expect it to be any good on highway,


    alot of factors to consider when deciding upon an axle ratio, but 3.07 is horrible,

    personally i think 3.73 without real tall tires is a happy overall useful ratio


    good luck
