'05+ Ford Super Duty Dana 60 Axle Tech & Info

I just regeared two 14 bolts to 5.38. One with Revolution and one with Yukon. Back in the day you had to grind the 3rd pinion support area for clearance. Neither of these gearsets required any grinding. Makes me wonder if they can now get the 14 bolt up into the high 5's ratio wise with a little grinding.

Both regears were 07' ish housings. You bring a good point. I was grinding on the old drum brake housings for gear clearance. Do the new housing have more room?

Not sure. Thinking they might....but solely b/c the master install kits are different...but that's mostly pinion seals AFAIK

I think a lot of stuff got crushed during cash for clunkers....and that 60s stuff is 60+ years old, so time is taking its toll on the stock. The D70s have some quirks with pinion offset (most are 5/8" offset) and other things that can make them a bit harder to source parts for. Unless you go 2nd gen Ram or newer....they'll be pretty narrow to match a 72" '05+ SD60 too.

Again, not complaining about the new choice at all...just wondering (hoping) if Revolution's got another card up their sleeve for the Sterling or something else. Right now, if you can't find a D70, I guess D80 is the target....though I'm not sure if that matches up well to a SD60 even with the 10" RG since bouncers are really the D80 crowd now.

is a LP 9” based axle not strong enough for what you’d want to do?

About half of all wonton trucks from 1960-1980ish had a D70 of some sort. Every DRW van based chassis made in the last 50yr has had some sort of D70 with some minor exceptions. I'm not sure why they're not more common. I know the pinion shaft D60 sized but people don't really have problems with those and with the kind of mileage built rigs tend to pack on bearing longevity isn't really an issue.

I feel like there's a fair number of builds from the heydey of the old site that had them but these days the high dollar people go 9" or 14B and the low dollar people go Superduty on both ends.

Dana70s are awesome axles.
It's just that 14 bolts are better. And cheaper to upgrade.

So why would you put all this work in a D70?

Not a big fan of LP 9" b/c of the driveline angle....but I'd definitely consider one with 10" gears (the big pinion 9" don't go much lower in gears than 4.56s).

And I'm honestly not currently in the market for a 6.17 D60 gear anyway....

I wasn't specifically talking about my own builds....just more in general.

Only reason would be to get lower than 5.38 gears....which is why I did it.
 
So, where were we on 17's fitting on 05+ axles? If it's a no go, I'll go back to looking at 99-04.
 
17s ? Like 17" wheels ?
They came factory with 17s so you're good.

Work trucks still come with 17s up to 2018 for 100% sure. Pretty sure they still do.

More hypoid offset. So the head of the pinion is bigger.

I still don't see how that allows for 2.00-7.50 but 14b can only do 3.55-5.38s

My guess is it's more of a demand thing then it's actually impossible.

If condition, completeness, and price are the same, is there a best year range to consider for a SD? My concern is mainly outers(c', knuckles, unit bearings, brakes) and not the gears/width. Let us assume new bearings/brakes will be bought.

I forget the exact interchanges but I think they are(car-part interchange search):
2005-2008
2009-2012
2013-2016
2017-2021

In my case, rims are 17" but I'm not above adjusting them or the brakes.

Any opinion of best range to start looking for? I'm hoping to get something to my axle guy before end of next month.

Well, sounds like if you want 6.17s, you'd want the '17 and newer...

According to BKOR's site, the 2013-2017 has the larger brake bracket spacing of 10"....vs. 8.5" on the 2005-2012.

Also from BKOR....

IMPORTANT NOTE:


If your knuckles have two "windows" in each knuckle (pictured below*), typically seen on 2018 and newer Super Duty knuckles, they cannot be machined for high steer arms. We can not accept these as cores and we will not be able to refund the core charge.


We also cannot accept knuckles that have eliminators welded in or high steer arms welded on as core returns.

Awesome info. It looks like 'ideal' is before 2018 if one wants crossover or hi-steer at the knuckles. As an aside, how bad is the stock f250/f350 steering for angles? For one project, I'll be sprung under with zero lift(FJ40)

Then it is down to brakes and rim choice.

Not necessarily....Barnes has weld on crossover steering kits for '17 and up...

I'm sure there are other weld on kits too...just depends on if you want that type of set up.

The older than 2018 limit is more if you want your knuckles machined for a keyway on a steering arm like BKOR does. Read the descriptions too....the one for the '17+ SD60 says 4.5" or less backspacing on a 17" wheel is required to work with their arm (for example).

At least around here, a lot of yards charge based on age....so a 2009 is going to be $550 and a 2017 might be twice that (which IMO, is too much....unless I just had to have a 6.17 gear and couldn't find a 2017 cheaper anywhere else).

I think my rims will be okay... maybe:homer:

I haven't seen anything locally less than $1k or so... but I've got a couple ebay spots that will ship for $750:eek: LQK and Benzeen play the bullshit car-part advertise super low local price and then tell you "oh yeah, $450 more to ship it to your local shop" bait and switch:mad3::flipoff:

Look around on co-part.com. You can find bent housings occasionally ask them to cut everything of and send it to you.

It wouldn't be hard to fill that top hole either. That would make me feel better about running high steer on those. It may not actually be needed, but it wouldn't hurt.

Are you talking co-part.com or car-part.com? co-part seems to be complete vehicles. car-part is parts and has a lot of bait and switch ads:shaking:

I have a nearby f450 2wd that is available that is tempting me like something fierce. I know the unit bearing would have to get swapped to 8 lugs which isn't a big deal since I was going to buy new anyways.
 
Sorry car-part.com. I’ve bought a whole set of outers and inner c’s for couple hundred bucks off a bent axle.

I wasn't using complete axle... just outers. D60 center will get dump-runned.:homer:

Where you located? I've got 3 pumpkins with tubes torched off. Local yard was scrapping them and I said, cut the tubes, I'll take the centers with me right now.
 
One other 'odd' question that I haven't seen brought up. How far into the passenger side center housing can one get a 2.5" spring perch?

In the red box of the following picture:
Super60Offset_cutPerch.jpg


My project(FJ55 base) is ultra low mid-axle width with a snow plow partial wheeler... 60" WMS. My current plan is Tahoe leaf springs(~54") plus leaf springs sliders that I like the results on another project(~$400 in parts) Unlike project I like the results on, I want to go sprung under. Other project uses a Dodge kingpin 60 narrowed to 60"(ie has cast in perch)

Coil overs are out of the question(cost). Plain coil springs might be an option other than packaging(Scout steering box in the way on outside) plus cost of all the linkage parts. Coil spring plus shock outside of the coil is a lot to ask for a 29" wide frame:homer:
 
Car-part.com is a search engine. Individual yards have the ability to enter false inventory. Don't shoot the messenger.

14bFF ratios start at 3.21, and there is no 3.55.

Are you planning to make the axle passenger side drop? There is another thread on just that.
