Is this dually Factory or "homemade"?
 

I ran across this truck on CL a while ago.
It was advertised as a 1988.

Is it a cab/chassis with a regular bed?

Or is it dual wheels on a regular truck?

This is the only pic, I have never seen it in person.

I have a 1984 4wd regular cab dually cab and chassis with a commercial flatbed on it.
I don't like the flatbed, it is too big and wide and I'd like to shorten the frame and put an 8' bed on it.

Homemade, or a mismatch of parts. The factory dually pickup will have the large add on fenders on it.

Keep in mind the dually pickups have a wider rear track. The cab chassis dual rear axle would be tucked closer inside the box side.

Agreed. Could have been a SRW (single rear wheel) 1-ton that had a cab & chassis (tow truck/flatbed) rear housing swap.

Re: Is this dually Factory or "homemade"?
 

thats a cab a chassis truck with a bed stuck on it

Re: Is this dually Factory or "homemade"?
 

How can you confirm this?

Re: Is this dually Factory or "homemade"?
 

hit the nail on the head, i have seen this many times

Re: Is this dually Factory or "homemade"?
 

how can you not? dual wheels that are as wide as a srw truck. unless he welded two frames together cause dual wheels on a srw truck will hit the frame. then its still a half c&c truck.

SRW (single rear wheel truck) 67.5"

DRW (dual rear wheel truck) 72"

C&C (cab and chasis truck) 63.5"

Re: Is this dually Factory or "homemade"?
 

I can't find the thread right now,but isn't a cab & chassis 4" longer than a regular truck? Cab/box combo? I'm with SCOTI on this one,started as a CrewcabSRW that had a dually rear put under it.

Re: Is this dually Factory or "homemade"?
 

I will have to measure the spring hangers for sure,but my 86 K25 was a converted dually when I got it.All the PO did was put longer studs on & he made it into a dually & the tires didn't hit the frame..

Re: Is this dually Factory or "homemade"?
 

and like i said the inside tire would hit the frame on srw truck. with this truck im sure they had to widen the tubs in the bed.

Re: Is this dually Factory or "homemade"?
 

Just went out to shop & measured my 86,the spring hangers on same width as my other 3/4ton trucks.The 86 was a converted dually when I got it & the tires didn't come close to the frame.It has a deck on it,so tubs are not an issue.

Re: Is this dually Factory or "homemade"?
 

Single Cab, Cab and Chassis would be longer than a pickup dually (135.5 vs 131.5) but a 4 door cab and chassis and a 4 door pickup (with or without box) have the same wheelbase (164.5).

Re: Is this dually Factory or "homemade"?
 

I think SCOTI is talking rearend width,... not chassis wheelbase.

Re: Is this dually Factory or "homemade"?
 

I know it was an answer to Rubble

Re: Is this dually Factory or "homemade"?
 

You can't bolt dually wheels onto a regular SRW axle, so it's width would not matter anyway.
Actual axle housing length is not really the issue, it is from one wheel mounting surface to the other that matters.

Re: Is this dually Factory or "homemade"?
 

That's what I was thinking about,single cab & chassis..

Re: Is this dually Factory or "homemade"?
 

That's the way this 86 was when I got it,looks like the PO put longer studs in,then bolted dually wheels to it.I don't have any pictures because I singled it out.Duals don't work very good in mud or snow.Its a14 bolt full floater under a 3/4 ton truck.I just changed to shorter studs & bolted some wagon wheels on.

Re: Is this dually Factory or "homemade"?
 

My point was its just as possible it was a srw truck that had a rear axle swap..

Re: Is this dually Factory or "homemade"?
 

srw axle with duals would hit frame the frame isnt as wide on cc in the back

Re: Is this dually Factory or "homemade"?
 

I think you mean they would hit the leaf springs.
There is no way they would hit the frame first

Re: Is this dually Factory or "homemade"?
 

my city has some

Re: Is this dually Factory or "homemade"?
 

Exactly. Seems more than 1 guy has swapped a C&C axle under a dually as an alternative to widening the dually fenders when doing the 10-lug big wheel swap.

Re: Is this dually Factory or "homemade"?
 

in the truck i posted, the wheel tubs are a little wider. is it possible that i private company did this? i would love to built a narrow axle "big dooley"

Re: Is this dually Factory or "homemade"?
 

the leafs are no wider than the frame idk what you mean im saying the inside tire is gonna rub metal if you try it on a regular frame width truck. even without a bed.

Re: Is this dually Factory or "homemade"?
 

cc trucks frame rails are closer together than a regular dually. you will run into that when ordering tool box beds for example. a cc axle on a regular truck you inside tire is going to be touching they dont clear alot on a reg dually even. to make this work you take a c&c truck put a regular bed on it and cut the tubs to widen them. i have been around one or two that was done. one they just cut the tubs off and left it open in the bed

Re: Is this dually Factory or "homemade"?
 

My point was the leaf spring is outside of the frame rail.
You kept saying the tire would hit the frame.

Re: Is this dually Factory or "homemade"?
 

i get ya but its going to be into all of it. look at srw truck a stepper would be the best example now look at putting a 8 inch wide tire on the inside of the stock tire no way you can clear. you could shorten its frame and remount the springs to clear but jesus that a huge amount of work. i dont think your stock leafs would even clear a c&c axle enough to bolt up.

Re: Is this dually Factory or "homemade"?
 

you could 4 link and it may fit to get single wide wheel on the back with a deep offset. dually wheels though have no offset on the inside wheel.

Re: Is this dually Factory or "homemade"?
 

The cab and chassis axle and the SRW 1 ton axle have the same spring spacing and are the same width. (all the 1 ton axles have the same spring spacing) The difference in WMS surface is made up by the hubs. The cab and chassis axle uses dually hubs to move the wheels inboard, the springs are in the same location as the SRW 1 ton axle (you can convert a SRW axle to a C&C by changing to dually hubs and moving the backing plates inboard, the axles are identical). A cab and chassis axle is a bolt in deal on a 1 ton pick-up, the inner duals will not rub on the springs or the frame. The only modification that will possibly be needed is the inner wheel well/bed floor. Look at the picture, the outer dual is out side of the outer wheel opening wheel, so the full width of the duals is not completely under the bed. This is a fairly common modification.


So just to reiterate....

All one tons (DRW, SRW, and C&C) have the same spring spacing
while all 1/2 and 3/4 tons have wider spring spacing.

You can not bolt a one ton rear axle into a 1/2 or 3/4 ton or vice-versa. You would need to either change spring hangers or relocate the spring perches on the axle tubes.

And I'm about 95% positive that the C&C frames are the same width as all other trucks, they are just longer from the back of the cab to the rear axle.

Re: Is this dually Factory or "homemade"?
 

really i was always told a c&c had a skinnier frame width and you had to specify which you had to get a flatbed even. i retract my previous then i was told wrong.

Re: Is this dually Factory or "homemade"?
 

I have found info on the 'net saying these were dealer modified possibly as company fleet vehicles. I don't know how true it is....

Re: Is this dually Factory or "homemade"?
 

somewhere on here there is a copied page from a Chevy assembly manual. I will look for it, but I remember all the frames being the same width.

Re: Is this dually Factory or "homemade"?
 

i may be thinking on the later trucks since i have more experience with them too. ive had several mid 90s up only had the one square.

this may be what im thinking of. the old ones might have not been like this.

Re: Is this dually Factory or "homemade"?
 

ok im looking on curts website on a 86 truck it says a c&c uses a different hitch. when you select c&c it says 34 inch frame but idk the width of a non c&C trucks frame. ill see what i can find out.

Re: Is this dually Factory or "homemade"?
 

The frame may be shaped differently too. I think the C&C frame might be flat in top (so bolting on a box or flatbed would be simpler) while the regular pick up frame is raised up slightly over the axle.

Re: Is this dually Factory or "homemade"?
 

do you know the width of your frame? that would make it easy to find out. i dont think there was any raised spot over the axle on either though. id have to look again.

corection both are c&c looks like they had the hump also

Re: Is this dually Factory or "homemade"?
 

I just went out and measured
34" is what I got
