14ff out of dually, Will it work?

You're gonna have to move the spring perches and shock mounts but otherwise yes. IIRC a dually axle will make your front and rear equal widths WMS to WMS instead of the usual 3" narrower in the rear.

Thanks for the reply, it helped.
all the brake parts are diffrent to the dully. so if you get a disk kit for std axle it wont work. do some searching on 14ff axles and see the big diffrences. but yes it can fit yours .
No
Measure the wms to wms, and make sure it is a 14 bolt...
A dually 14 bolt is significantly NARROWER because it would be out of a cab and chassis truck. The outer dual (with all the wheel's offset) is in the same place as a standard wheel on a srw 14 bolt...
A dually Dana 70 is the wider one.

This would require some serious thought: If it is indeed a 14FF, I don't think you will be able to move the spring perches outward the 1/2" required for a K5 without going disc brakes. I have had to bleed the rear brakes on a 14FF dually, and it is a bitch to get on the bleeder screw(tight fit next to the spring pack). While discs on a dually rear are feasable, it is quite a bit more expensive. Measure, measure , and measure again just to be sure.

A dually 14bff will work if you change the drw hubs to srw then you have a srw axle.
The only draw back is that there are no bolt on disk brake kits for srw this way. you have to weld the disk brake brackets to the tube as the flange is too far back.

I'd like to see somebody try and move the spring perches out 1" per side on a C&C axle to make it fit the K5 spring spacing. 
(Okay.... you could do it if you put on discs or did something else with the brakes
)
