dually to single wheel?

[illness]

I have a 2001 SRW superduty.

I have access to a Dana 80 out of the same year truck.

What all is involved with swapping these axles? Will I need spacers for anything? I want to run the same rims on the front and back.

Not sure, But I will bump it for ya. Why do you not love the fat bottom girl anymore?

I was told they are the same rear end, just different hubs. But, after looking, I dont know. I would have to put on a set of SRW tires and see if they looked right. When you take off the fenders, your gonna have to put on some flares to go over the bed, cause the bed has a 1.5" cutout going across the wheel well on the duallies..

Not real sure but the measurements might be longer on a dual rear. but you can install a dual into rear setup. Ive noticed alot of pulling trucks are going dual.The duals are dana 80 ,and singles are 10.25 or 10.50 I think.

460-from what i can find online, you are right. the dually is a dana 80 and most singles are a sterling 10.25 but some have dana 60s.

xsracinggt-not going to have to deal with dually bed cutouts because its going into a single rear wheel truck keeping the original bed. do you have a dually and have some srw tires hanging around?

i want to know if i install the dually rear in a single rear wheel truck with a single style wheel....... will the tire location appear stock or stick out or be too far in?

For the front all you have to do is remove the spacer and then it's the same axle as the SRW guys...

For the rear you could do it but you'll need a spacer to make them stick out the right width IIRC... and of course you'll have to address the cut out portion of the bed!

so the dually rear is a little shorter width than the srw rear?

what is IIRC?

what and why would you need to cut a portion of the bed if simple spacers could position the wheels in the stock srw location?

No, what Marty means, is that the bed has been cut out under the Dually Fender. You would have this gap if you used a dually bed. I dont have a set of SRW wheels laying around to see if they would be too far inside the wheel well or not. Sorry, but what Marty said aboove about the spacer is probably right. You might even take the spacer off the front and move it to the back. That might work.

I thought about that but I'm not sure if it'd work or not...

someone needs to try!

Does anyone have a tape measure? Go find out... I know very little about superdutys, but duallys have been my thing for a few years... I'd go out and measure mine right now if it was here, but I can't ...

What matters is the (WMS)wheel mounting surface-to-wheel mounting surface measurement. On a dually, it would be as simple as measureing from the outside of the outside tire on one side, to the inside of the inside tire on the other side. (for example, left side of the left tires, to left side of right tires, would give you center-to-center measurements, and thus give you WMS to WMS.) The old chevys I know of were about 69" on the front, stock single wheel trucks, and about 66" on the rears, 1/2 ton thru 1 ton trucks. From compairing my '00 F-350 to my '84 K-30, I'm guessing you'll find the rearend WMS-to-WMS to be about 69-71", the frontend may be about the same, if you dont have DRW spacers, as mentioned in earlier posts. Moving these spacers would push the rear wheels out WAY TOO FAR in my opinion, but I am basing all my knolage on my cab and chassis truck, might be wider than the standard bed models.
From what is sounds like to me, you want to swap a dually rearend into your single rear wheel truck? My guess is that the bolt pattern would be the same, the WMS measurement just might be off... If it's not much, it wouldn't hurt to use it anyway, the older trucks (my chevys) were all that way, 69" front, 66" rear, made the front tires stick out of the fenders when you went with wider/biger tires, rears still nicely under the bed sides... just looks funny. Good luck...
