Good Lockers?

I am building up a 75' F-150 (393 stroker, and 44" Boggers) and I have a Ford 9" in the rear and I am going to get a Dana 60 for the front.  I am looking around for lockers for the diffs.  I want it set up to where I have a limited slip condition when I am not locked in so I can drive down the road and down some hard dirt trails with out putting too much stress on everything.  When I flip the switch to lock the diffs in I want it to be totally locked in so all 4 tires are spinning.  I have been looking around to see what would be my best option.  I have heard that with air I might be able to rig up a fitting so that if I or someone els gets a flat I could air up a tire off of the compressor which would be handy but there are also these OX lockers that use cables that I was looking at which with cables it would eliminate air lines and electrical connections.  I'm not sure what to get or what would be best but I want the ability to drive on the road with out any uneeded stress on the system that possy would put on but I also want the option to flip a switch and lock everything up.  Not sure what to get and any suggestion will deffanatly help.  
It takes big nuts to follow us.

a detroit in the rear would be a good choice...it unlocks when turning ...other wise either the air, electric or cable locker are the only locker to choose from....btw isn't a 9 inc kinda small for 44 inc tires and a stroker??

Go with the OX lockers they're aewsome, and yes a 9 inch is a little on the light side for 44's and a stroked engine.

I would stay away from a Detriot as they have no ability to power both wheels at different speeds in a turn (they never tell you this) as do all replacement lockers too. You want a selectable locker. Also, I concur the a 9 inch is light for 44's (real light)

Even (real light) is being optimistic. More like: Non-existant, Transparant, liquid. And that's with open differental, with it locked, can you say:Unconceivable carnage, just add gas pedal.

Ya agreed with the rest of them.  A 9" is way, way to light for 44's.  I would choose a D60 or D70.  And if you get a D60 out of another Ford then it should almost fit.  I did that with my 71 F100 and I only had to cut of the perches and weld new ones on a little closer together cause my springs werent as wide as the donor truck.  But it was simply procedure.  I had the swap done in under 2 hours.

even a dana 60 as a rear axle isn't gonna cut it.....seriously original poster what r u thinking running a 9 inch with 44s?? you need at least a dana 70 or an 80, maybe you could find a newer sterling 10.25/.50 or hey how bout a good old reliable gm 14 bolt

Yes even a D60 in rear is "light" for 44's on a full size 4x4 if you have any power at all and want more than a parking lot queen.  

Ya,  true, but you can do some upgrade to axleshafts and similar stuff to them to strengthen them up.  A guy here has a Ford Bronco with a D60 that is running 49.5's and hasn't had a problem with it yet.  But a D70 or 80 would definently be much stronger, but even the 60 can be made to handle it.

eh.... a dana 60 still only has the 9 and a quarter ring gear which is gonna be the weak point even if you do upgrade the shafts and ujoints....some people get lucky and have them live for a while....but really its not made for that kinds of stress....why do you think dodgde didn't even think about a rear dana 60 for its cummins powered trucks? and thats with stock tires..they ran the dana 80 and now aam 11.5 those are real big boy axles...

Ya, maybe he's one of those lucky ones.  But it isn't something I would do, I probably wouldnt run anything bigger than 37's no matter my axle, once you get too big of a tire and too much of a lift the truck looks just plain stupid, that's just my thought though.  But ya I would definently go D70 or 80 for that big of tire.

A GM 10.5 is plentiful and cheap for a rear axle and more than a match for 37's and then some.  

Ya, not much into the GM stuff, at least not yet anyway.  Right now I am running a D60 w/ 33's.  Once I get some money though for a new set of rubber I think I going 36 or 37's.

I understand you maybe not wanting to use GM 10.5 axle but I mentioned it because they are easy to come by and very strong (stronger than a D60 and about the equal of a D70 and a lot cheaper)  

Ya, I just throwing my opinion out there, not really swayed toward them yet, but you kinda caught my attention.  If I would of known this before I may have gotten something along those lines instead.  But ya it sounds like a good deal if he hasn't gotten anything else yet in replacement of his 9"
