Hey guys,

I am from the 80-86 forums and am looking for some measurements from your duallys, I am looking for a candidate for a swap for my rear axle.

All I want is anyone with a dually will you please give me your measurements from inside tire to inside tire.

also if your willing:

(1)leaf spring width, (2-1/2" or 3")
(2)from outside of leaf spring to outside of leaf spring

Also please post your Year, Model, Rear axle if you know it, and if you know if you have a cab n chassis or a pickup style truck

Thanks Again Guys,
Devin

Also feel free to post pics of your duallys, and we can make this a post your pics thread too

 

the pickup DRW axle is the wide one.it measures approx 59" between brake backing plates.
a srw pickup and cab n chassis axle are greatly narrower.if you have a cab n chassis, really all you need to do is buy a srw pickup axle and just re-weld the spring perches were you need them.
if you have a dually pickup,then your stuck paying for this much more expensive,and wider rear.

 

OK, what I am looking for then

Can I get a measurement on a SRW pickup rear axle backing plate to backing plate

and a measurement on a DRW pickup rear axle backing plate to backing plate

and finally a measurement on a cab n chassis rear axle backing plate to backing plate

Of course still include your rear axle, etc.

According to the theory, that there is no difference in axle width between DRW vs SRW, is what I am worried about. therefore a pickup SRW and DRW should be the same width from backing plate to backing plate and a cab and chassis could be something different, but still the same between SRW and DRW cab and chassis.

Thanks Again,
Devin

 

"On a single rear wheel 10.25" Sterling axle, high part of the brake backing plate to high part of backing plate you will measure 54", the frame is 37.5" wide outside to outside.

On a dually that had a factory pickup box with flared fenders the measurement is 58" high part of the brake backing plate to high part of backing plate, the frame is 37.5" outside to outside.

On a factory cab and chassis the backing plate to backing plate measurement is 54", and the frame is 34" outside to outside.

On the cab and chassis 34" frame you can run dual wheels with the 54" housing because the springs are 3.5" closer together.

On the 37.5" frame you need the 58" factory dually rear end housing to run dual wheels."

not that it matters a whole lot,but i know the DRW pickup axle is 1"+ wider than Dave thought.
when swapping one in my 250,i measured the bugger to be approx 59 1/4 wide between backing plates.

your not still not saying much about your setup for some reason.why keep it a secret?
if you have a pickup you need the pickup drw axle.there is only one way around it,with arrowcraft drw adapters.

the cab n chassis f350's run duallies because their frames and springs are narrower.this is why they basically just run a srw pickup axle with spring perches set closer together see?

more info here if your interested:
https://www.ford-trucks.com/forums/1...is-or-not.html

that will help you understand the differences between the 1st and 2nd gen sterling and how to interchange between those easy enough.

the truck i see in your signature,is a long wheel based cab n chassis.
the much wider pickup drw axle isn't anything you'll need for that rig.
edit,
nope maybe not.is that a crew cab f350 cab n chassis? why didn't and don't you provide info on your truck when starting a thread so we know what you have?

 

Thanks, those measurements were really useful;

So do you think that the SRW pickup axle and the Cab and Chassis axle are the same from inside the backing plates, hence the 54" measurement, and the pickup DRW pickup axle is a separate axle.

So in reality there are two different axles:I feel like I am trying to fit a square peg into a round opening trying to find an axle to fit this truck

Can you tell me if the new axle has ABS is the axle going to be no good for me?

or can I bypass it

looking at www.car-parts.com

and I see a few DRW 4.10 pickup axles,

one for $350 and claims to have no ABS

I am really just looking for a way to match up an axle back in VT that I would likely get for free.

well i sure thought the srw pickup axle and the cab n chassis axle were 100% identical expect for the where the spring perches were welded on.
apparently not according to dieselbrad on here though.
i find it very strange they'd make these different.-if it's true,it was poor planing at the sterling plant imho.
however,i know they are interchangeable regardless because we've seen it done on here.people buying the wrong axle for their cab n chassis and having to move their spring mounts and as far as i know it works perfectly.

the f350 drw pickup axle however is the only one that is greatly different.it clearly measures much wider.


your current 1985 (cab n chassis? ) axle doesn't have a ring tone and sensor for abs or vss.
if you buy a late 80's - 97 axle with one,it just won't be used on your truck that's all.


there is a free vin decoder on here if your not sure if you have a pickup or c&c.
what happened to your axle?

 

No mine is a pickup axle/frame,

So I can just get an axle with ABS and pay no attention to it, correct?

My truck was advertised as a dually, but it was an SRW, so I need to get a dually axle before I can run dual wheels. frustrating

Also will the 10.25 bolt in, and does it matter if the donor is 4wd or 2wd?

I think I might go for the one at the junk yard for 350 on car-parts.com
