As far as I know the front axle is napco but I haven't really found oututch about the heavy napco axles yet as for the t case it is a divorced Rockwell

 

This would be awsome to do to dads D600, just need to find the right parts to make it work.

Mexican Dodge trucks - http://dodgeram.org/ki4cy/ram_picts/Mexram.htm

 

Note that the wheels on the pictured truck (which I am assuming is a 2010 model) are old-timey "get-your-head-torn-off" two-piece split-ring rims with 20-inch tires that have pretty much been obsolete in the U.S. since being outlawed in 1978.


It is hard for me to see in the other pictures, but the wheels on the Mexican 1-ton trucks also look to be split-ring.

What is a constant aggravation to me is that, although since 1978 it has been illegal to have a split-ring wheel on an American manufactured truck, even today it is perfectly legal to import them on Canadian, or import trucks, and no restrictions whatsoever have been made against their use on non-highway equipment.

The way I see it, your head is still just as gone, regardless of whether from a U.S. made wheel or a foreigner.

 

nah I think that is a dated photo, it is of a 2nd gen cab even and hood/fendertops/headlights. Basically the front clip is derived from a 2nd gen ram, not even a 3rd gen so highly doubtful it is a new 2010 4th gen but still, yup those are the split ring wheels. Hmm I'd love to crawl around that rig either way.

 

Half the school buses at work, all of which are 2001 or newer, have those kind of rims. The part that mounts to the tire is a single piece, which is why they're not dangerous. The old, dangerous kind of split rim like you'd find on a very old truck used two pieces on each side of the tire bead, clamped together by a third piece.

 

I think you might be a little confused about what we are seeing.

The general design of the pictured wheel/hub combination is a DAYTON hub, which can be had in either single-piece/tubeless wheel configuration, or the old killer style multi-piece split-ring.

There are many variations of multi-piece "split-ring" wheels, some having a single split-ring that snaps into a groove in the rim.

Some are three-piece, having a continous outer ring that is held on by an inner split locking ring that snaps into the rim groove.

Some have a solid ring with the rim itself actually being split.

Old fifties and sixties GM 3/4-, 1-, and 1+1/2-ton had a very deadly notched solid ring that was simply held into the rim's groove by air-pressure and proper alignment alone.



And the worst of the bunch, probably killed more good men than small-pox, is the old BUDD style of which the rim is made up of two separate halves that "spring" fit, one half over the other, held by imagination only.


I deal with this junk every day and have since I was in diapers a long time ago; I have seen holes torn through roofs, holes blown through block walls, sides torn out of fuel-tankers from a ring blowing off the truck sitting nearby, arms and legs torn off, you name it; and, I hate to walk past one of those wheels sitting in the parking-lot.

 

Yeah, the rims on the Mexican trucks look exactly like the Dayton wheels on the buses we have.

I bought a '48 Ford dump truck once that I scrapped except for the cab and engine. If I had tried to take the wheels to a shop to get new tires, the shop would have been legally obligated to destroy them.
