dual rear wheels

I have a 77 f-250 two wheel drive. Over in the local wreaking yard there is a 79 1-ton dually. I starting thinking about buying the rear duals off the one ton. My question, Do i need to make any modifications to the rear axle to bolt up the wheels? OR could i just bolt the wheels on?

I tried this many years ago and it won't work-I think you can swap the complete rear end though-or go and check out Arrowcraft - Dual Wheel Conversions for a quality adaptor kit to do it with your current rear.

Dana 70: The rear end makes no difference whether it has SRW, or DRW.

What is different are the hubs, drums, lug studs and etc.

F250's were not available with DRW's.

There were no Styleside pickups available with DRW's until 1980, and then...F350's only.

Prior to 1980, all F350's with DRW's were sold as a Cab & Chassis, or with a factory installed flat or stake bed.

Also, the frame on the F-350 is probably 34" wide while your frame (unless it's a high boy) is 37.5" wide. Chances are the inner duals would rub.

1967/77 F250 4WD's (High Boys) have rear frame rails that are 33 1/2" apart.

Some F350's thru 1979 also have these narrow frame rails, some have frame rails that are 37 1/2" apart.

All other 1973/79 F100/250's have rear frame rails 37 1/2" apart.

I have a dual rear wheel adapter kit on my f250 4x4 crew that I am not going to use...I know it was an add on but it is available, pm me if anyone is interested in it.

Arrowcraft does not make the drw fenders for the dentsides any more. I sold a set to a guy in Colorado from my 77 crew cab, I just took the duallies off and put on aftermarket 10" wide rims.

Just got through doing my fronts, they're a direct bolt on. It was said earlier that there is no difference in the rear? Only about 4" inches a side. It's true the hubs and parts will interchange but the axle width is shorter in relation to the DRW. Just swap front hubs and the complete rear and save $ over the arrowcraft stuff which is not as strong and will cause problems if you load it heavy, say with a gooseneck.
