I have a goal of commonizing my trailer spares to the 8-on freedom pattern.
For reasons I'd like to have a dually trailer axle, and I'd like to use (4) SRW type wheels.
Obviously there'd need to be some kind of spacer to get the tires far enough away from each other to mimic the spacing dually wheels have.
And my bearings would be pretty far inboard and might be kinda pissed at me.
Have there been any factory applications like this? I can picture a few ways to make the spacers, just sorta interested in understanding all of the ways that these applications might have failed in the past, to ideally work around their shortfalls.
 
At one time there was a company making spacers to do exactly what you are talking about. You saw them on some conversions like Centurion used them. Toyotas, couple others like that.

I tried to find them a few years ago and could not.

Now and then you will come across a thread of people looking for replacement studs. The kit came with spacer and it's own special studs.

Closest thing I've found was something guys used for truck pulling. Still ended up using a dually wheel on the outside for more backspacing. But if you stacked two of the spacers together or ran skinny tires it could work.
 
We had dodge bobtails in the Air Force for towing AGE that had this type of setup. They were constantly breaking studs, but that could also be a result of a short wheelbase and tight turns on the flight line.
 
My pops had a jeep that had duals front and rear it was strange to drive.

I've got a set of those. Because. Never used them.

 
Just make 4 really short axles and put the inside "dual" on from underneath the trailer.
 
Action fabulous did it right. Certain size square tube “axle” holding a ft or so of cut off spindle end truck axle add weld, Fill tube 1/3 or so with gear oil for the bearings.
 
If you're not going to center the tire loading between the bearings, you're just asking for more headaches.

Another thing is the packaged width. Dually trailers already have narrow frames to accommodate dual wheels; you'll miss out on the advantages of the inner dual wheel being dished over the brakes to save on overall width.
 
You really want to break stub shafts off the trailer axles don't you? It wont work. Can this thread be moved to the towing section?
 
A drw wheel is roughly 12-13" from wms to tire edge.

The arrow craft/western hauler GOOD spacers are 4".

How wide is your trailer axle?

Pick your width and add aprox 17"x2, 34" to your oaw.

So, if you have the inside clearance you can go straight to drw wheels. And only gain +/- 8" x2 oaw


You can add drw spacers and add drw wheels so you dont have retarded mismatched wheels and width. So + 34" oaw.

You can add stupid to stupid and buy 8 spacers, and do the dumbest thing possible. And add again roughly 30-36" oaw and a retarded amount of leverage to the spindles.


Btw, if youre gona stack spacers ontop of wheels, you had goddamn well better have flat faced inner wheel. So theres another 4-8 wheels you need to buy.

I scalped a set of arrowcraft/wester hualer spacers out of the junk yard 20y/a.

I used them on my srw 14bff to match drw front width for h1s. Beat that poor bastard pretty hard.
May have had a bent spindle when i yarded it out but id say it was more my fault than the spacers.
 
Well this is interesting.

FYI. Most dually trailer axles have 9/16 or 5/8s studs. While single wheel ones are 1/2”

19.5s sound like a better option.
