DRW Axle on SRW F-350

I'd like a bit more rear axle capacity on my F350 than the stock 7000 lb model. I thought of getting a dually and the going to a new bed and Rickson SRW conversion.

But thinking about it, I think the easier swap is to put the 10,000 lb DRW axle on my truck.

Anyone know about this? Spring perches the same? Frame? Other stuff?

I know 1999 to 2004 Dana 80 used on the F350 Duallies has the same spring perch width as SRW pickups. Uses the same 8x170 lug pattern and 14mm studs, but I can't recall if they are 1.5 or 2.0 pitch. A friend of mine runs one on his 2001 F350. One thing to note is that the wheels will be about 3" further out per side. I believe the 2005 and newer use a 8x200 lug pattern, and 2012 they went from tone ring on the differential to wheel speed sensors in the hubs.

Cab/Chassis versions have a narrower chassis = narrower spring perch. Could cut off the perch and weld back on.

So they probably changed the back axle when the changed to coil spring suspension. I was looking at the factory dimensions and noticed that the cab/chassis were narrower so the narrower frame makes sense.

Thanks for the info. It's very helpful
