I know that Dana builds the axle to Ford’s specs. They (Dana) are pretty good at building axles for a number of companies and applications.
For a multi purpose rig that will see its share of street use the Ford speced SD60 Dana axle has a lot of shortcomings.

Most of my comments are going to be based on the 05+ SD60 however there is a tremendous amount of overlap to the <05 axles. The short side is really short. Not much room for anything till you start cutting the center away. More than one person has cut into the tube by accident and welding that cut isn’t real effective. Have seen a number of broken short sides. Cut tube ? Not enough engagement with the center ? Center not strong enough after cutting ? The center’s position is often in the way of things like track bar mounts and frame rails on compression. Often the DS angle from the TC output would be better if the center (pinion) was moved towards the passenger side a bit. ***short side is so short*** Overall width is another. Though that is a trade off. To achieve a decent Scrub Radius you need wheels with plenty of backspacing. Steering angle may or may not be compromised with the wheel/tire getting into things it shouldn’t. The axles I’ve worked with have measured out to have 9-10* of separation from caster to pinion angle. In more than one instance pinion angle has been compromised to achieve decent (6*+) caster. A lockout on the hubs fixes the speed issue on the road. While a moderate speed on the driveshaft with the hubs locked up ends up being the only way around the DS `s crappy angles. Because you’re stuck with what the Ford Dana or is it Dana Ford specs are. IF you know what your doing welding to the knuckles can be done successfully. Problem is the resulting steering geometry has no Ackerman and parallel steering at best. The location of the DL on the knuckle can limit the steering angle as well. It been tough for many to get the TB and DL the same angle much less the same length. How about the steering stops ? You want adjustable positive stops to avoid breaking things. The upper BJ has been an issue with a number of wheelers. Several folks are making kits to fix it but none of them are really end all fixes. The offset heims for the TR to clear the diff cover are another band aid. A few folks have been able to modify the diff cover with a notch but that is not the norm. TR droop and roll is often the reward of making everything clear. The 1480 and 1550 joints are not much different in capacity. The 1550 is larger in order to accommodate more steering angle but according to Dana Spicer they are only fractionally stronger than the 1480. Yes the buy in is cheap. Working around all the “issues” depends a lot on your ability and ambition. Doesn’t take long and your “cheap” JY axle starts eating up serious cash. Rather buy a bare center (with or without tubes) and build an axle to meet my needs. Can set the pinion angle(s) where they need to be. More leeway in positioning the center left to right so it plays nice with things like TB mounts and frames. Crank in whatever caster I want. Take advantage of the improved steering geometry. Set the width to whatever it should be. The ability to use shafts from places like Branik or SpiderTrax that have a lot of great features over standard designs. More expensive ? Depends on a lot of factors, including perceived value in performance and capability. Running Currie RJ`s front and rear stuffed with SpiderTrax shafts and outers plus Blaine Johnson brakes. Bought bare housings. Machined/pressed in my own tubes and built the axles from there. They fit, they work and in the end the investment was worth the money. YMMV but that’s my take on all this. If I had to do it over again the only thing I **might** change is the Reid S60 outers.... Maybe....

so I am about to do this with an '05 axle. I am toying with the weld on kits....artec, JHF, barnes, etc.....I feel lik artec has the best kit from looking at the design.
Also considering just a straight tie rod with offset heims in a nearly stock location, or even bent tierod with normal heims, in a nearly stock location....I dont need massive high steer, just above the knuckle mount. Considering rasing it say 1" or so above the knuckle and double shearing the heims.

Consider the Reid 05 passenger knuckle...which is a copy of the factory Dana Ford/Ford Diana .... instead of weldon’s. Pick a HS arm that you can machine the DL pivot to. This will help address your steering angle.
Fusion 4x4 has a TR that captures the cast arm on the knuckles. If you look at the pictures of the JHF weld on’s you can clearly see how the TR mounts. A position that is common with all the weld on kits and one that really messes with your steering. If it’s a trail only rig than weld away and make stuff fit. The dirt and the speeds don’t care.

Here's what I did : Buy 2 05+ axles for $500 each. Press out the tubes so I can work with 2 long tubes. Shorten both to my desired length (in order to provide for the width and pinion location I wanted). Install C's to provide my desired caster angle. Add FourwheelSupply steering arms (which do keep akerman, unlike the weld on units) and let you put your tie rods higher so you don't have any issue of them contacting the diff cover Sell all the left over parts from both stock axles (R&Ps, stock shafts, stock brakes) for $500. Total is a pass drop HP60 with the strongest center section, C's and knuckles that are available from a stock axle that cost me about $500. I understand that buying all new name brand shit is cool. The products themselves are great. But my solution let's you realise the exact same thing for a tenth of the budget without any strength compromise. You can use shafts from Spidertrax, Branik etc the same way. Also, I've worked with a bunch of 60s. About all the different versions. The 05+ stuff is, by far, the beefiest and strongest 60 variant that is out there. Last edited by Bebop; 10-16-2019 at 09:01 AM. |

Sooo, basically you're saying the pumkin isn't in the right place and the C's are clocked wrong for your application.
Here's what I did : Buy 2 05+ axles for $500 each. Press out the tubes so I can work with 2 long tubes. Shorten both to my desired length (in order to provide for the width and pinion location I wanted). Install C's to provide my desired caster angle.

Your approaching this whole axle business much differently than the vast majority of folks. ![]() Not many even think about retubing much less have the ability to do so. Your taking advantage of beefy products and making them fit your rig and your specs. All with a good ROI which just adds to the whole scenario. ![]() Way back when I had access to a waterjet cutting machine. We would jet the plug welds and push the tubes out. Similar to what your doing. Than build the axle around the rig. Sadly it seems most folks don't even bother fabbing something like this up anymore. ![]()

I dragged myself into nothing. The OP asked several basic questions. My response was a suggestion to rethink what he is doing as a whole. Another poster asked if I would expand on my comments. I did so hitting some of the high and low spots of the SD axle. Now you come busting through the door whining about costs and effectiveness along with ROI. By your own admission you comment on how you would like some bling but can’t afford it. Because YOU cannot doesn’t mean others can’t. Tell me how a under tube truss is going to solve some SD short side issues. Tell us how your truss will improve steering geometry. What are you sacrificing in ground clearance ? Tell us how you’re setting for pinion angle in both the X and Y dimension. How are you doing your knuckles ? Please expand on your comments. Perhaps you have ways of doing things we can learn from. One guy responded in detail on how he used two SD axles and made one good one. Personally I think that was a helluva good idea and told him so. All you’ve done is bitch and whine because I don’t conform to your ideology. Are going to bitch and whine that I run an NV4500 and an Atlas too ? How about the blingy blue PowerTank with their digital readout pressure gauge that I use to fill my tires ? Grow up and learn to open your mind before opening your mouth. If you don't like my comments there is a feature called blocking. Welcome to use it should you desire.

Not everyone has the skill, time and tools to do what you did. Your one of the first folks I`ve run across that actually went back and built their axle from the center of a late(er) model axle in a long time. Most folks simply buy parts and weld them together at best. Not really understanding what they are doing and why. If they did then the build would be a lot different. Did mine with blingy parts because that's what I wanted. Doesn't make me any better or worse than the next guy.

So in his first post OP mentioned that cost was Factor... then you drivel on about a fully custom axle. Quote:

But to answer a couple questions, i will lose no ground clearance... if done right and thoughtfully, the truss will not be any lower than the diff. It will not fix steering geometry, it really doesn't have any issues that i will face. I think your perception of such deficiencies is how you're justifying the $$$$ you spent. Knuckles and pinion will stay in stock geometry, and im going to run 1410 double cardan. I also doubt it will see any speeds over 45 mph in 4wd. If you're not racing, and you're using 4wd over 45 mph in any vehicle, you're doing it wrong imo. Never once said i couldn't afford it, i said i wouldn't unless i was using your money. You'd be surprised if you came to my house and shop... Why would i block you? There is potential to learn from you. This just wasn't the thread for a class, which it seems like you have none of ![]() It seems that other people in this thread have called you out on your nonsense that has no place in a thread that asked simple questions about high steer options for the stock configured axle. Like i said, i think you came here to tell everyone how cool you are for building such a sweet axle. It sounds sweet, and likely will last forever, but still not the answer to the question at hand. I'm definitely not jealous, I'd rather spend my money elsewhere. As for me "busting in the door" i was commenting in this thread before you and had relevant info about being able to find a local shop to machine the knuckles for the bolt ons, as I've had good luck with local shops machining my knuckles on my current Dana 60 when i had no clue how to do it. Thank you though, i love being called cunty, i really have been feeling cunty lately ![]() That's pretty sweet, just a press and torch, I'd like to see that. I have both and might be happy to try this on my next build.

![]() I used two 99-04 SD60's (used two long side tubes) and a HP44 center for my front axle. 60 center wouldn't fit where I needed it to, and no need on this particular project. Machine the tubes to press over the stock 44 tubes, and weld. ![]() Still doesn't help the hi-steer dilemma though. ![]()

I first started out looking at the weld on due to the cost savings since a lot of people have success with weld on. After researching the weld on and talking to a company that is one of the common top choices they said if your going to run it like an Ultra4 don't run a weld on, get a bolt on.
I would have no problem welding it with with the correct methods. But I still never was comfortable with the idea. I decided bolt on was the way to go so I could sleep at night and not dream of having the high steer break off and cause me to drive off a cliff and burn to death in a pile of twisted metal. Bolt on methods varied so much as well as options for sending the knuckles out. By the time I was done researching. I saw the high steer in my head and figured it was easy enough to weld up a high steer bracket and drill and tap the knuckle and mount it. This allowed to put the tie rod location exactly where I wanted it. The bolt on design also grabbed the knuckle over more area than most key or step using smaller studs in a concentrated area. In the end I'm confident it is the strongest solution using the stock knuckle. Going to an aftermarket knuckle designed for high steer would be a better solution but I can not justify the cost and need. Pictures of it can be found on IG @Dustdynamics |

Sorry for taking part in the massive thread derail @Prizefighter I hope you got some good feedback that you were looking for. I bet in the end this thread will also help others since the super duty Dana 60 thread is full of nonsense talking about nonsense that's hard to find any info without rereading the whole fuckin thing all over...
