    Will running 5:13 gears and 35" tires make my freeway experience a nightmare? This is a 14FF locked and Dana44 open.

    I would think youd get a killer launching type effect out of the hole :D i was gonna run that setup at one point and time, i think it would be fine. IF you have a 700r4.

    now i could be wrong but i had a tranny shop tell me one time, that with the 700r4, 35s and 513s..you would have a nice crawl ability, and when the over drive kicked in, it would be equal to 410s...
    don't know how true that is tho..

    Fourth gear: 0.7 x T-case high: 1 x Differential: 5.13 = Final Drive: 3.59

    i would do it ..i'm gonna run 4.56's with 33"s

    I am running 4.88's and 35's, I wish I had went with 5.13's. At 65mph I am turning about 2200 rpm and up around 75mph I am turning around 2800.
    I say if you have a 700r4 then go for it.

    35" AND 3.08
    Yea I need to re-gear. I haven't put my truck in overdrive in the 2 weeks I've had the tires. Still waiting for that cheap D60 to swap in before I do gears

    if you do alot of 80+mph commuting i would go with 4.88

    otherwise 5.13 with a 700 that has a functioning lockup converter would be sweet. especially for a weezy stock engine.

    yep, go 5.13 and don't ever look back. :grin: the 700 has a nice low 1st gear (for an auto) as well, so you'll have good 'launching' ability.

    No reason not to run 5.13s, if/since you are gonna regear, on a truck with an OD trans. OD will bring the gearing down so much like others have said, bringin it to a reasonable level...plus it gives for flexibility if you ever wanna go bigger...even 44s if you wanted (not that i would ever do that). Im gonna be gettin a 14b in a few weeks, gonna gear it to 5.13s, and run my 33s for a lil while...its all i got and can't afford the whole 9 yards at once. It will be a fun lil ride to work and back and i shouldn't have to worry about freeway driving with it...I wouldn't want to run 5.13s with 35s if you do A LOT of freeway driving...but if you do a lot of wheeling and city driving, i say go for it.
