Running in 2wd low?

yes, there is a very good reason... you're doubling the torque input of your axle 100% of the time. wouldnt be surprised if that would eat a 14FF or a D70.

does that mean that those of us with 2x the torque of some other people shouldn't drive at all? haha j/k, but the argument doesn't seem all that critical to me
x2. A ff14b will be fine... especially if you're talking about driving on the street. It takes giant meats and mad torque and lots of traction to break something in that axle 99% of the time... I just don't see how driving to the grocery store is gonna do much to it. 2x the torque is pretty much like doing a big block swap into a rig that came with a 305 or something. Its all good.

what gears/tires you runnin to consider runnin low on the street?
either way i think you'll be fine. id just resist the urge for hard launches.

I wouldnt worry about the torque at all, those 14 bolts and 70 can takee huge amounts of stress. The only thing you might want to consider is taking out your front driveshaft or something. I dont know if it would be a good idea or not to let your lockouts spin without the hubs locked
You should be able to get away with it around town and stuff if you want to play a little, but not really sure why you would want to run 4 low on the highway. You basically would have equivalent gearing in the 6:1 range with only 35" tires, and that's really low gearing for trying to cruise down the highway. Would really think you would be limited in top speed quite a bit.......not like you are trying to run 44's or something.

He is running a twin sticked case the front shaft is not spinning so its fine.

I run mine in 2 wheel drive low range on forest service roads and if I am going to be putsing around town. keeps me in high gear more of the time and I figure is prbably easier on my tired old engine.

i had my front drive shaft off my burb and did a breakstand and it blew up the yoke and then my driveshaft spun around and f-ed that up too... that was also in a 10bolt too but id be careful
I'd see what the big deal is. 2wd low with 3.07 rear is like having a 6.14:1 rear end. I doubt you will break anything.
Just run it and be done with it.

with 3.07s its painfully obvious that you're running 1/2 ton axles. you're pushing the limits of the axles as it is with 35s, double your torque input, and they will give. no, it wouldnt be like running a doubler, a doubler would almost quadruple the torque, where you are only doubling it. of course, anybody who has a doubler runs 1 ton or beefier axles too.
put a 600 ft/lb big block in it, and see how the axles hold up. they wont!
if you really need more gear, swap the weak 1/2 tons out for a set of 3/4 tons, you'll get more strength as well as a better gear ratio. 3/4 tons generally come with 4.10 gears, which should work nicely with your 35s.
