14FF strength?

It would depend on the amount of traction available. If you where muddin then a hell of a lot. If you where in the rocks, not as much, but still alot more then just about every other axle smaller then a Rockwell.

I kinda want to know how much raw power it can handle with 39.5's also. I want to run the same combo.

It can handle all the power you can afford and then some, as long as it's in good condition and has lube in it.

yeah, well I've seen 44's with 600 hp and it was alright. But they werent trying to do truck pulls on pavement either. I don't think you'll really have to worry about breaking a 14 bolt FF. If you do manage to break a shaft (not really that likely unless VERY rusted) you can get a set of custom alloy shafts made that will give you a boost in strength and probably never break. In fact the stock shafts are stronger than some of the early 2.5 ton rockwell axles.

Why not do like the rest of us? Put it in and try to see if it'll break (for awhile) then stop worrying about it and have fun running it. I have a VERY healthy big-block, lots of extras and a 14FF that has never let me down.
I run 39.5's on my 14 bolt with a detroit and have never had a problem. Thats after two years of mud racing and mud bogging and even a week long trip to moab. I know quite a few people who beat them hard and the only thing that I have seen break on them is the stock locker. I beat the hell out of the housing on Lower Helldorado with no problems also. I think the only upgrade you can do would be a Rockwell.
If I were you, I wouldn't worry about the rear. These rears are just indestructable. Almost impossible to break anything. Focus more on other areas like the front axle, t-case, etc. /forums/images/icons/wink.gif
If you want to further beef the rear axle, get some Moser Engineering alloy shafts for around $300. /forums/images/icons/cool.gif

Thats the real reason I was askin, thanks Wes. Should I cut it to the quick and just get the Moser shafts. Have one, not wanting to play with stupid pereferral BS later. Aside from those with the MOO unit, anyone else trussed a 14FF?
Drew, whether you actually need the Moser shafts will depend entirely up to you as to whether you want to spend the cash on them.
As of today, I still have not seen one 14FF shaft fail from breakage or misuse. I have not even seen one where the splines got twisted.
I have seen the spiders go bad on open and Gov-Locked carriers. But still no bad shaft or anything.
I would say the Moser shafts are the last step you would need to do in order to upgrade and beef your 14FF. The stock shafts are already "overkill" from the factory with 1 1/2" diameter shafts. 30 splines is close to 35, so, they are still stronger than most people think. /forums/images/icons/wink.gif
BTW, while most people (not CK5!) think the D60 rear is more stronger and bulletproof than the 14FF, they fail to realize that the 14FF is more comparable to the D70 instead.
I won't even talk about a D60 rear. I have seen those go bad just as easily as a 10 and 12 bolt rear. /forums/images/icons/tongue.gif

I doubt that little 350 will ever tear up a 14ff. /forums/images/icons/smile.gif Hell it had a 10 bolt with 5:13's behind it so you will be fine.
