DANA M210 / DANA 44™ ADVANTEK® FDU 4.27 ELD

[DRC]

I have been thinking about getting a M210 FDU from Ford Performance but wanted to stay at 4.27 Ratio for my 2022 Outerbanks Non-SAS with Advanced 4 Wheel Drive.
But Ford only offers the 4.46 and 4.70 Ratios.

Been doing a lot of research and found this Catalog from danaaftermarket.com
It shows part numbers for the DANA M210 / DANA 44™ ADVANTEK® FDU 4.27 ELD
Axle Assembly 10139180
Ring and Pinion Gearset 10104510
Diff Case Assembly 10157367
Standard Install Kit 10267427
Master Overhaul Kit (WHICH COMES WITH SHIMS) 10267428

Thoughts;
The complete axle assembly is currently not available from Spicer Dana but the rest of the parts are.
Even if I built this FDU would the Procal 4 or Forscan allow me to change to the M210 with 4.27 ratio?
Also would like to change the Hero Switches and get the FDU wiring harness so everything works as Ford intended.
Do know that I will have to get new half shafts.
I believe the hero switch would be part number M2DZ-13D730-GA
Not sure of the part number for the FDU wiring harness yet.
Does the Diff Case Assembly 10157367 and\or the Master Overhaul Kit 10267428 come with the ELD solenoid or external brackets needed?
My main reason to go with 4.27 ration would be that I could leave the rear diff alone and stay with my 33 inch tires and not loose gas mileage.

Anyone else have any thoughts?

Go to the 4.70 gears, 1000%. The only reason to upgrade to the M210 is to off-road harder and if you're gonna off-road harder you want to go to at least a 35" tire. It makes sense to re-gear when you're upgrading, I think you'll regret it if you don't.

I got mine from @tomsoffroad76 and they have a pigtail plug that you can buy as well to hook up the locker switch....yes the Procal unit will let you select that ratio.

4.27 is OK but 5.38s will make your truck feel like a rocket with stock tires!

Interested in this as well. I have a BB with 4.27 rear locker and Having the option to add the front is Something to consider down the road.

So far I have been happy with the open front diff. Live in the mountains and have had quite a bit snow this last winter. Driven on some pretty rough dirt roads to get home a few times. The Bronco never stopped going and made me very happy to get my family home safely. Just want to have the option to lock the front just in case I do need it. This thread was started to address technicality of doing a M210 4.27 FDU. Maybe Ford will address this whole thing in the future. I may very well go with the 4.46 and 35" tires. Thanks

It’s a simple swap. You will need Procal if your current M190 has FAD. Front locker is easy on aux switch. Will be a bit more difficult with hero switch.

Zero chance I wouldn’t regear it to at least 4.7 (when already spending the money to make it more off-road worthy) if it were mine but to each their own. WHEN you end up going to bigger tires you’ll be glad you did. I’d also seriously consider going 32 spline and adding half shafts to the cart

Can you give me a link to that part number 10179978, unable to find the part number on Spicer or Dana Aftermarket website.
Found this link for 10139180 https://www.danaaftermarket.com/spi...D/10139180?cp=1&catalog=PIMS_NA&partType=PART

Thanks

That part number was on a paper provided to us with the axles we received to build for the Bronco DR.
It will have to come from a distributor. It also includes all the part numbers to complete the installation..

It will be from the Off Highway division.

4.27 to 4.46 is not worth the squeeze . When spending money on gears if it's not 10% or greater it just won't be worth the investment. I would suggest going 4.7's if you are going to regear with your current plans for use.

At this time I would like to keep the 33" tires and not lower my MPG.
And not have to spend any money on the rear differential.
I have been able to drive through some pretty difficult trails and the Bronco just kept going forward. I'm amazed on the handling.

Did you ever make progress on this? I like the 4.27’s as well and do moderate off roading. Just picked up a core M210 4.7 FDU. It needs gears and bearings replaced anyway.

Still doing research on the M210 but have purchased new rims and now plan to go with 35" tires.
Still have plenty of tread on my 33" tires.
I'm hoping in the mean time they do offer a M210 with 4.27.
Looked at the Dana site today and they don't have the 4.27 ring and pinion set in stock.
But there may be after market ones available, maybe eaton, yukon, etc.
What vehicle did you get your M210 from?
I might also put a ring and pinion into a M210.

The one I picked up came from a badlands sas. That was in an accident. I have not opened it up yet to check it out but was told debris were found in the fluid and they just swapped it out. Was told to treat it like a core the case is not harmed. I have not taken a meter to the coil yet to see if the locking actuator(magnetic coil) is still good. I’ve been on 37’s for 20k miles. Still can get near 20mpg on freeway depending on conditions usually 18.5. Done some moderate off roading. My wife complains about tire spin even on dry pavement so I’m hesitant to up the gearing but understand why some would want too. This is about as crazy as I get except for windrock trips I don’t have those photos on my phone on the bottom pic what you can’t see is it’s a little more than 3’ drop off.
