Is there any difference between the axles themselves or is it just the hubs?

DRW hub on SRW axle?
- Thread starter RamSST
- Start date
just the hubs, you can swap hubs between the axles with no problem
mmmmm. What axle? I'll assume we're talking 14BFF. (The D70 uses the same hubs, IIRC, but there are more variations in sizing.)
The C&C dually 14bff has the same tube and shafts as the SRW, yes. The differences are in the hubs and the brakes. The brake mounting flange is ~2" farther inside on the dually axle than on the SRW, matching the fact that the hub is 2" farther in.
Now, there IS a *wide* dually 14bff, but they're pretty rare, and would only likely be found on late 80's trucks, including the IFS body style rigs.
If you're going to be swapping DRW and SRW hubs, expect to have to do something about the brakes: either weld-on brackets for a disc conversion, or cut and move the flanges for drums.

Yep just the 14bff thanks for the replies. hmm I wonder if I can find a cad drawing for the Dually hubs anywhere. So there should be no different in the axles? I bought a SRW axle and my plans for it may be changing to possibly a DRW setup instead of the SRW
Waaaaayull ... you need not *necessarily* change hubs to go DRW.
See, the only difference between the hubs is that the WMS scoots in 2" for the dually ...
SRW:
DRW:
The duallies also have the crazy deep drums (3.5" shoes instead of the 2.5"
wide on the SRW?), which make up the difference.
Anyway, you can put dually wheels onto an SRW hub and/or axle, though you'll want to check clearance for everything for fitment. That includes tires to the springs, tires to the body, and wheels to the brakes. Especially pay attention to brake fitment, as it's a serious PITA with the factory 16" wheels. (If you're doing crazy aftermarket wheels or something nutty like 19.5" commercial stuff, you'd be fine.)
(Oh, and you'll prolly need longer studs and maybe the goofy rings that go on the factory rims, or maybe new lug nuts, etc etc. It snowballs rapidly.)
After a tremendous amount of fiddling and welding, though, your truck can look like this:
That's the "stealth dually" in my sig
It really does look stock, except it has more tires in the back than it should ... most people don't notice, but the Chevy-hip among us do a double take

hmm good to know. I do plan on going to a 19.5" wheel and commercial tires, So If i leave it with the SRW hubs then I'd be sticking out an extra 4" total?
Well, your WMS would be 4" wider, yeah.
How far your tires stick out is a function of the tire width, wheel offset, etc etc etc.
But yeah, all else being equal, the SRW hubs make the axle wider than the DRW, which just seems wrong. The key is that the C&C axle is narrow to make the outers parallel with the fronts, right, and if it were a D70 or one of the rare wide dually 14B axles, the tubes are way longer, so they stick out something fierce even though the hubs are in, if that makes sense.

yep makes sense thanks. Well at least I know I don't have any major work to do to the axle to put dual rear wheels on it. I was thinking about doing a 10-bolt conversion adapter so I can put a 19.5 or a 22.5 inch wheel on it. IS there any difference in the front axle?
Uhh. Mine's 2wd, so I can tell you all about the spindles and springs ... but you say "axle" so you prolly mean 4WD.
IIRC, the difference up front is a *wider* WMS, created by different hubs and rotors on the Dana 60.
You could also do wheel spacers, though some would poo-poo them, or do like some of the big rigs and have normal offset wheels up front and then the duals out back. Presumably you'd carry a spare for the front, 'cuz the back is already carrying the spares
With mine I was specifically making it a solid, heavy-duty 1-ton-class tow rig, with no intent for wheeling ... and trying VERY hard to restrain myself from doing some variety of 10-lug wheels, and a C60 front clip (mmm, flip-up
) and ... eventually it'd be easier to just buy a damn C60 and be done with it. There was a guy who was putting a Suburban body onto a C60; sweet rig, tons of room inside, and depending on the WB of the donor truck, could prolly fit a flatbed BEHIND the Burb body and have the best of all worlds -- A

yeah I guess I'll be searching for a D60 now I only have a 44HD
your srw axle will need the studs swaped in the hubs to drw longer ones for full lug nut contack with drw rims on them.
4x4 dana 60 axles are the same for gm trucks except the hub/rotor assembly. its srw or drw with the spacer built in. you can get drw axles cheeper than srw as most want to convert to srw.

I'm talking for the front. the 14bFF should be strong enough behind a diesel
