Lower gears = Less stress on drivetrain/axles?

    I wanted to run this by a few, only because to me it makes sense. With a lower ratio, arent you having to put less stress (because of more turns of the pinion for every turn of the tire) on the pinion to get it to spin? Its kind of like switching into the lower gear on your bike, making it much easier to pedal... What does everyone think--would you have a better chance of blowing a u-joint or a t-case with 3.42s or 4.56s?

    It is better with the lower gears. I had a real problem exploding drivelines and breaking transfercase adapters with the 40"s and the 4:11's. I went to 5:13's and have not broken anything yet.

    When you go to lower gears you increase torque output at the rear wheels..... so with that in mind, its harder on everything past the gear reduction(ring, differential, axles) and easier on things(axles, ujoints, t-cases) prior to the gear reduction.

    less stress /forums/images/graemlins/thumb.gif
    i'm running 5.13s
    that's why my "piece of junk", "that thing is gonna blow up 208" transfer case has been holding up.

    I bet the low range in that thing is nice too.

    that's the main reason i want to keep it.

    with everyone swapping them out, there shouldn't be a problem with me finding one when ever mine "explodes".. /forums/images/graemlins/thumb.gif
