Dana 60s are confusing

['84 Bronco II]

So I guess 05+ should really be 05-16 now. End of an era!

I know they went to Mxxx metric shit in 17, I'd guess the knuckles and outters stayed the same.

More info on the rear axle would be cool to know also. I think they have a few different options depending on F250 or F350 and gas or diesel.


Side note, when is someone going to make deeper than 5.38s for a HP 60? All these Jk's on 40s would greatly benefit from ~6.17s

The Dana 60 in the '17+ stuff is not an Advantek axle, it is more akin to the difference between a JK "next-generation" Dana 44 and a legacy Dana 44 (still has the same hypoid offset as a legacy Dana 60 as far as I know).

As for the rear axles, The Sterling 10.5" is still in the lower GVWR F250s, but the Advantek M275 is what is used in the high GVWR F250s. All single rear wheel F350s use the M275, and dual rear wheel trucks have the M300.

Here is a quick spec breakdown on the rear ends:

So I'm debating between building a 60 or a 14 bolt front axle for my Blazer, either way I need the steering parts off of a 60 and I'm finding a lot of conflicting info out there on what's what. I'll try to list what I've found here, but I'm sure some of it is wrong and I'm hoping someone will help me out with some clarification and correction. And no, I don't need all this beef out front in my current configuration, but my 10 bolt isn't going to last with an LS and 37s plus other future plans and I don't want to have to upgrade twice, so I'm taking the "go big or go home" approach. It also sounds like the much simpler way to put either of these in a GM is to switch to a driver-drop transfer case, but that's a whole different discussion.



SD 60 are in 99-04 superdutys (F250-F550?). 30 spline inner, 35 spline outer. Good axles in general. Can be made to accept 35 spline stuff, and maybe 40 spline, with extensive modifications.



05+(not sure what the upper year is or if the current ones are identical) there is a SD and a SUPER? All 35 spline inner and outer but at least 2 difference in knuckle sizes and 2 different u-joint sizes. SD is in the 250-350, Super is in the 450 and 550 but could be had in the 350 somehow.

Super 60s have 1550 u-joints and SD have 1480. I think the Super 60 has a better turn radius because of the different joints and geometry. Same tube diameter but Super is thicker wall.

I'm not sure if the R&P and lockers are interchangeable or not, but is sounds like the super 60 uses a larger R&P from the factory. Not sure how this affects the choices in ratios and lockers.

They both seem to suck for high steer kits, not sure about crossover steering. I want hydro assist, not full hydro.


Am I headed in the right direction here? I really feel like a Super sounds like the better donor for a 14 bolt, but the 05+ SD sounds like it'd be just fine in most rigs in its stock form. 99-04 Sounds like it really doesn't have many downsides other than the 05+ being stronger, so it'd be a good budget friendly option maybe? And anything is better than my 10 bolt, just don't buy a Dana 50 (which I'm not even sure what those were in).

check out the 05+ superduty axle thread here https://irate4x4.com/general-4x4/4199-05-ford-super-duty-dana-60-axle-tech-info

youre close on most of the info

99-04 has 35 inner and 30 outer, you can machine the unit bearing housing to accept 35 spline outer and you have to make sure you dont pick up a D50

05+ d60 can be upgraded to 1550 u-joints no hassle and cheap, can upgrade to 40 spline but itll cost ya some $$

skys sells complete high steer kit

all the links and more info are in the other thread...... SIRCH N00B!


side note: ive been looking to see if anyone has run leafs on the 05+ d60's and havnt seen anything, i think its a move

as for a donor you could always just pick up a 14 bolt and then go SUPERKINGPINS

Hey, I posted in the newb section on purpose. Haha.

I am starting to think leafs is going to be the better option for me. The more I read and learn the more a radius arm setup looks like it sucks in the rocks. I don't know that I want to tackle a 3 or 4 link right now. I haven't found a single person running leafs on a SD60, but I don't think that means it can't be done. I've got a full machine shop at my disposal and a welder that will help me with any project I come up with. Really not sure where I'm going to end up on this, saving money and planning for now.

If I win the lottery, everyone gets a set of those. EVERYONE.

Radius arms aren’t “great” but they work just fine. So many Jeeps have them as the normal lift kit long arm, all the old F-150s and Broncos. Just make the arms kind of long and kind of flat. Mine were mounted closely together at the crossmember and that seemed to help with bind during flex.

Meh, I run radius arms. I havent noticed all the bad attributes that people say such a wheel hop, unloading, pushing under the vehicle, etc...Maybe mind is a unicorn, maybe the geometry is good, w/e it works, it's low, and it's stable.. . There is no way I would run the stock mounts on an 05+ axle...We swapped one into a bronco and without the radius arm mounts the lowest point is now the knuckles and the diff. I think you should decide if you want to stay leafs or go links...that would really set the tone for which axles are best for the amount of work....that said, the 05+ stuff is so beefy compared to kingpin 60's
