how they do that?

i remember several yrs back there was a truck on here that had dually wheels but they were tucked under a srw bed...how did they do that? i have been searching but no luck..im in plan mode for a build thats about to go down here

Probably using a regular SRW axle as a dually axle would be wider. You'd have to watch for inner tire vs spring contact.

yea im pretty sure the truck i remember had all the spring hangers swapped from 1 side to the other and they were mounted inboard..or sumtn similar

Y'all are overthinking it.

You do have to tub in the wheel wells unless you run really skinny tires. I'm running 235/85-16's, kinda wish I'd stuck with 215's.

Note this is on a 1-ton frame with the 40.5" spring spacing; on the 1/2- and 3/4-ton with the 42.5" the springs would be an inch closer to the tire on each side.

The axle is essentially the narrow cab&chassis dually. This has the same overall width and the same shafts as an SRW axle. But it uses the dually hubs which move the WMS *in* two inches each side (yes, I said in, not out) and the brake mounting flanges move in correspondingly.

Umm ... random pix:

If memory serves, that is actually using the SRW hubs, so I could *maybe* squeeze the tires in another 2" by using the DRW hubs. Again, be easier with skinnier tires. The wheels are sitting on thin spacers, 5/16" maybe. This is to clear the calipers on my messed-up disc conversion, which is gonna be removed and I'm going back to drums.
