Oh ok. Well the "F-Super Duty" was Fords "F450" truck and there's no mention of the F-Super Duty/F450 in his list there. The truck is even excluded under his D80 section. It's a pretty beefy rear on the '87-'97 F-SD/F450's with massive disc brake calipers.<br /><br /><br /><img src="https://cimg1.ibsrv.net/gimg/www.ford-trucks.com-vbulletin/1200x900/17b_diff_flush_e3a12b180a6ef1e4df462a500b975975915 9d735.jpg"></img><br /><br />Of course for it's time. Nowadays it's like a pickup sized rear axle lol! Ford has turned it's trucks into near medium duty trucks these days,it's insane.<br /><br /><br /><br />What are you planning on converting to a dually? I've converted my F250 to a dually using an F350 DRW pickup axle. If you have a pickup you just have to make sure to pull your rear from a f350 dually pickup and not a cab and chassis because it's much wider.Either the first or second gen will work but depending on your driveshaft you might need a conversion u-joint.If you have an E4OD truck and need the VSS make sure the rear isn't too early and without the tone ring (pre '88 or '89 or somewhere around there.)<br />2nd gen sterling's ('93-97) are more desirable but really unless your running massive tires,the first gens are just fine and last forever and a day too.I used a first gen sterling as that's the only way I could find 3.55 gearing in 10.25 drw pickup form and just used a conversion u-joint.<br /><br /><br /><br /><img src="https://cimg2.ibsrv.net/gimg/www.ford-trucks.com-vbulletin/499x278/chip_truck_0c1f5338c488daea81be8936bfa3541eb30d649 3.jpg"></img><br /><br />Here's the dually axle I put under her.Measured between the backing plates.<br /><br /><img src="https://cimg7.ibsrv.net/gimg/www.ford-trucks.com-vbulletin/956x636/drw_axle_c5463c6ac886c5a6c0eae79c867b5343232ebbff. jpg"></img><br /><br />That applies to F250HD and F350 SRW (as they are the basic truck/same platform) to convert either to a dually.If the "dually rear" you find is not even close to that measurement then it came from a narrow f350 C&C dually truck and it's not going to work.
<br />The term f-superduty does not represent the f-450 alone, it represent all Ford trucks 3/4 ton and up just like it does in today's trucks except these day it's just superduty.

That's a different term. The term your thinking of is "F-series".
"F-Super Duty" was a unique truck,larger than an F350 but smaller than today's F-550. "F-Super Duty" was built from '87 though '97 and it was a 15k GVW rated truck.In '99 Ford would start calling their 15k GVW class "F-450" and drop the oddball "F-Super Duty" term.
It's a stupid term that just causes confusion today, even more so as Ford would go on to use the term "Super Duty" (dropping the F) to describe their '99+ HD F-series pickup line of trucks.I wish Ford never used it and stuck with F-450.
Here's mine;
Though they come in various wheelbases,mines the longest one plus it's been custom stretched an extra 3' so none of them were this long from Ford.That part of the truck is a bit outside factory but otherwise the same.
Here's a description I wrote of the trucks;
The F-Super Duty 1987-97 (the original super duty prior to '99 pickups) was Fords introduction of the class 4 medium duty truck. It is a commercial cab & chassis 2WD dually only optioned truck.Though a few conversion co's such as (but not limited to) Quigley,did convert some to 4WD.They came with 460 gas engines all through the production run,with the optional 7.3l IDI diesel engine from introduction through '94.Then the optional 7.3l DI (power stroke) diesel from '94.5 - '97.
HD transmission options include both the manual ZF5 and the E4OD automatic.
Cab configurations were standard regular cab only.Though you may come across other options (super cab & crew cab) they were custom built.
Trim options were that of the pickups (XL,XLT).
Known at the time as the "One Ton Plus." It sports a HD frame and the mighty hydroboost brake system with four wheel disc brakes.The beefy sized calipers make stopping the heaviest of loads a very safe and secure truck to work.Though they are 2WD trucks,they are equipped with 4WD transmissions but rather than a transfer case,they come with a drive line parking brake.The driveline brake works great to hold the truck from rolling when parked.However it will do nothing in the event of an emergency rolling down the road (other than burn it's internal shoes up).There is no manual,emergency stopping device so it's of great importance to keep the trucks hydraulic braking system top notch.A HD dana 80 rear axle that came from ford with gear ratio options intended for two purposes; Heavy hauling & towing.They came in various wheelbase lengths with up to a 15,000 LB GVWR.It's widely known as the F-450 equivalent with many auto stores listing parts under either name.
These trucks are easy to identify with their pickup size cabs,yet unique F-Super Duty fender emblems & 10 lug 16" wheels.

I see. What's odd about that (and the reason I believed otherwise) is because the tech data we use in my shop (Mitchell prodemand) lists all chassis above 3/4 ton under the f-superduty submodel. When you selecting vehicle info to pull up tech data you have to select f-series for f-150 trucks or f-superduty for f-250 and up.
Oh yeah, I know. A whole lot of online resources, the DMV in different states, parts stores and insurance co's computer systems often have issues trying to identify these particular "F-450 sized" trucks. A lot of the computer systems,like your example is designed for modern stuff and what they did, was just rolled the old into the new terminology too, so it makes it hard to find these trucks, due to the old terminology changing it's meaning over the years.It's messy like that in all kinds of systems.It doesn't make the modern systems "correct" it just makes it mostly correct for today's trucks terminology so for like 99% of the stuff I suppose it's ok lol but not so good for the older stuff.
Look at them though.It's clearly no F150,F250LD,F250HD,F350SRW,F350DRW,or F350 cab and chassis.It's much heavier duty than those with 10 lug wheels,hydroboost brakes,extra deep gears and payloads of around 3 ton or so with GVW of 15k. Clearly the same sized trucks as today's truck that Ford calls "F-450". None of the pickups (nor the f350 c&c) were ever coined with the term "super duty" during their time period. Pre-'99 the term was always "HD/ Heavy Duty" when differentiation between light duty and heavy duty versions of the F250 was required.So clearly that's a modern computer system (using "super duty" everywhere) roll back/roll into one program,see?
If it were up to me, the marketing gimmick of "super duty" would of never been invented at all and I would of never built a light duty version of the F250.
It would of just been F-Series F-150 all the up through the pickup and medium duty line.Plain and simple and no junk needless terminology and no bs computer crap to deal with. An F-150 would of meant that and an F-850 that etc.But alas we live in a world of marketing gimmicks where things can't be easy lol.
I have a F350 dually pickup here with the stock 215/85/16 tires
I also have F-superduty here with the stock 235/85/16 tires.
What exact measurements are you looking for
As for the F-superduty(F450) built from 88-97 they ALL used dana 80 axles with disc brakes, NONE came with the sterling, D70 or drum brakes

Yeah that's when he had a misunderstanding of what the '87-'97 trucks "F-Super Duty" are due his modern computer system.Still not sure he's fully convinced,but that's ok.Can't force someone to believe ya lol.
Just to screw you boys all up...I'm running a drum brake cab and chassis Dana 80 in a pickup truck with the 3 inch leaf springs in the factory spacing
Uh? A Dana 80 from what? A Dana 80 from an '87-'97 F-SD/F-450 would have springs mounted too far inward to bolt up to a wider spacing of a pickup truck.If you moved the spring mounts outward and bolted one under a pickup to run SRW, why would you not want the disk brakes? What kind of u-joint conglomeration would that be?
That's awesome! She wasn't wide enough on her own to run duals so it must of come from a cab and chassis. What's the lug bolt count and pattern? If 8 lug, your factory wheels bolted on then or you just used the dodge rims too probably I suppose? What kind of Dodge vehicle and year?
Oh and what's the gearing?
The old dodge was a 12v so I guess it was 95-97. It has the 8 on 6.5 pattern but I'm running dodge wheels on the inside cause they run on the hub. There's 4 inch spacers to get the inners out from the springs then 3 inch spacers to seperate the duals. Ford wheels on outside
