how far could I push 2005 f-250 axles?

I have some f-250 axles (I think. Not shure cause I can't find any web site with my BOM registered BA 611356-1). How big could I put some tires on with lockers, atlas 4spd and 450hp engine?

I've seen quite a few broken on stock F350's out in the oil field. It's not the wheel speed it's that sudden stop!

54" Boggers. But just to play it safe I wouldn't go any bigger.

Well that depends on several variables, are you pushing uphill or down? How strong are you? Does said axle have wheels and tires on it? More info man, more info

I'm thinking about building a buggy around these axles. 44 boggers are my favorites but I don't want to spend big bucks on chromo shaft.

Project 1 would be: selling these to put $ on my actual rig.
Project 2 would be: selling my actual rig and trading one of my two ford front hi pinion dana60 for chevy passenger side front diff to make a rear mounted engine buggy with both diffs pumpkins on the same side.
Project 3 would be: selling my actual rig and building a front mounted engine with the hp dana60 and the sterling on the rear.

Don't be silly. He'd at least have to buy an after market bolt-on truss for the axle so it would handle those. Of course, then it would be tits

Anything over 52 inches and you're going to have to carry a bag full of unit bearings with you at all times....

I've heard that the '05up axles (radius arm/coil suspension) are 35-spline all the way out to the hubs, but I haven't verified it yet. If this is true, then I would agree 44" tires shouldn't be a problem if you're not real heavy, although you'll have to keep it somewhat conservative on the wheel offset (too much offset does tend to stress out the unit bearings, true).

35 spline is true...the bearings inside the unit bearings are also spaced slightly farther apart. Big brakes, which is nice...but stick you have to 17"s and up (and only some 17s)

stock 05 stuff on the left

Thanks for the pics. I've also heard of a spindle conversion kit tu use the standard type bearing.
Is it what you've got on the right side?

Left side is stock 05-08 unit bearing and stub shaft, right side is Solid Axle 99-04 freespin conversion. Kind of apples to oranges comparison picture...but what the hell.

Dynatrac just released their freespin conversion for the 05-08s, Solid Axle is doing research on it at the moment.


The bearings in the 05-08 axles are bigger and spaced apart further...I have only heard of one case so far of worn out unit bearings from those years (huge difference from the 99-04s). Im not being at all pro-unit bearing...but if you have a newer type axle, you may just see how the stock ones hold up, before going to dynatrac...you may be surprised. If you ever need a freespin though, let me know.
