1 TONS!!!! and do wat im about to do swap out teh hubs n spindle to ford dana 60 hubs n spindles (35spline, n lock outs) then get a EMS cad delete shaft kit

 

You can fit 15's on a60. You just have to grind a small amount off of the calipers. The rotors are the same diameter as on a 44, the calipers are a slightly chunkyier than 44 calipers

 

I've seen one cummins w/4.10's. Everything else had 3.55's, like mine.

And many medium duty trucks on the civilian market. More importantly, they are an affordable/plentiful 2 1/2 ton axle with good aftermarket support, from companies like Ouverson.

Some of the early (94-95) 2500's had a 44/9 1/4 setup with 8 lug hubs on them. So be on the lookout. Also, the HD v8 2500's had a 60/60 setup, while the v10's and diesels had a 70 (w/auto tranny) or 80 (w/manual tranny) out back.
