Yes, the f350 dump truck I worked on had that beefed up frame. Since you have a cab and chassis truck, your truck is completely oddball from the cab rearward compared to a regular dually pickup. The frame is more narrow, the rearend housing is more narrow, you have a large stack of leafs in the rear but they are narrow also. A pickup bed will not fit on your frame if you ever had that notion.

The little f350 dump I worked on was 4x4 also. If you take the other guys advice and install a tranny and transfer case, then you will 1/2 of the way to 4x4. Later on you could swap the front axle and have 4x4, though I am not sure what your front suspension looks like now. Does it have leaf springs or coils up front?
The front end has twin I beams, coil springs. Here is a pic of the truck. It came as a flatbed. I found out that not all F350's have the same springs in the rear.

"
Also, this frame underneath has on both sides a long strap riveted to the bottom to add rigidity. Has anyone seen that before?
Just went out and counted the leaf springs, yep, 10 on bottom plus 4 more auxillary springs. (to ensure that smooth floating ride) Why go see a back surgeon to fuse your bad vertebrae? I can rent you this truck for a small fration of the cost of surgery and guarantee this ride will fuse your whole spine in one day.
The transmission I have is a Zf5s42, is there any advatage to having an s47? "
outside of the deeper reverse, no. 4x4 s42's can be found much easier compared to a S47. as a result, it should be a little cheaper to acquire a 4x4 s42 and transfer case since there were more F250's and F350's with the same trans.
I understand. Suppose if I swap out my tranny for the 4x4 s42, a new driveshaft will be in order, will have to do my homework. Thanks Towcat.

Yes again what you have is a cab and chassis f350. So the frame is completely different aswell as the leaf springs and rear axle. Like stated a regular Truck bed won’t fit and neither would a regular axle or leaf springs

Biggest giveaway for an F-Superduty (That is what the fender badge says)

10 Lug Wheels

Straight 2wd Rockwell Front Axle not the "Twin I-Beam" front suspension.

I like the cab & chassis frames. They're more resistant to buckling when (ab)used hard. My buddy has one under his '93 Grizzly (mini-big-rig).

A 4wd ZF5(42) and appropriate transfer case don't have to cost a bunch. Fixed rear yoke readily available in Broncos, late OBS trucks, and Superduties. They're not gold mines like the NV4500 and 241DHD.

You can also look for a diesel zf s5-42 with a 5.72 first gear. Yes they did make them. My dad had one in his dually. The lower first gear also gives you the lower reverse gear. Another thing the 460 zfs came with the lower geared version. Many have modded it to fit the diesel. I know @Dieselcrawler has done a few.

I've also heard you can reload the diesel ZF case with the gas gears.

3.79 to 4.66 or 5.24 isn't nearly as noticeable a change as 3.79 * 2.69tcase = 10.19:1

Plus, you've sacrificed a 'driving' gear to have a maneuvering gear.

The 5.xx 1st and R in the Cummins dodges (G360 and NV4500) aren't a cure-all. Those ratios are okay, but I still prefer lo range for trailers. I miss the close ratio S42 w/tcase in my F350. Best of both worlds.

ZF5 ratios here:

Dodge Getrag G360 ratios here:

NV4500 ratios here:

Are you speaking of my truck as having 10 lug wheels? 10 lug wheels start with the F450's correct?

I like my setup as well. This truck is very stout. Believe it or not, this truck was given to me last summer by a friend of mine. I spent around $3500 in parts, not counting my labor, before I started driving it in Nov. Clutch, tranny are still to be done. Along with ip and injectors but runs fairly well. Am looking in classifieds now for that 4x4 s42 with transfer case.

Throw in 6 new Firestone transforce tires so am at roughly 4500 but am just starting to get this where I want it to be.
Thought about a spicer and brownie box combo.......but there is no room I think. From most posts I read, most are satisfied with the ZF trannies, so will keep it simple.

My experience in Florida looking for one of these trucks was not good(in the junkyards). I ran around all over the place looking for a hard line for the injection system. I was in the Pensacola area but searched electronically all the way to Jacksonville. The cash for clunkers took a lot of these trucks off the road and out of the junkyards permanently.

I don't know if you picked up on it in a previous post, but you can use a 460 zf and transfer case if you are brave and can drill some holes. I don't think it is too bad using the bell adapter as a drilling guide.

Not to threadjack, but if you have the Superduty/F450 ZF trans with the parking brake, which transfer case would swap onto it?
