cab/chassis to dually bed

Other than the obvious shortening the frame, brake lines, drive shaft... What would be involved in swapping from a cab and chassis to dually bed. I know the rear end is narrower, will it fit under the wheel wells of a bed? I've done several lwb to swb just not sure on the dually axle. Thanks in advance for any help.

If memory serves me right they used Dana 70's in the regular 1 ton trucks, so might have to swap the rear axle?

Re: cab/chassis to dually bed

Yeah the axle is a bit narrower on the cab/chassis. If you go to a fleetside bed, you'll need to redo the wheel tubes in the bed to allow the tires to sit in closer. Or change to a normal, slightly wider dually rear end.

The do look neat with most of the wheels under the bed instead of the big ballon fenders, but you lose bed space.

Re: cab/chassis to dually bed

thanks for the help. Are the spring pads in the same location with both axles? or would I need to get hangers from a non cab chassis/relocate perches on dually axle?

That part I do not know, especially on the square models.

All 1 tons should have the same spring perch distance, whether SRW, DRW, or C&C, all of which being narrower than a 3/4 or 1/2 ton spring perch distance.

You generally have 4 options.

1. Keep what you have and build a flat bed/utility bed

2. Swap to a full width dually axle and a dually bed

3. Swap to a SRW bed, widen the wheel tubs slightly, the tires will be about flush/hang out slightly from the fender. I believe I recall the interference to the inner tub being slight, as in, potentially depending on tire setup, I've heard of some guys clearing by a hair, to some hitting. A slight lift in the rear would also clear, if you don't intend to twist it up much.

4. The C&C and SRW 14 bolt axles are an identical housing. You can swap hubs/brakes from a SRW onto your C&C and have a SRW axle.
