Front Differential
Had my '05 set up with a rear Detroit Locker and a Detroit Truetrac in the front, loved the set up for plowing.
Now have an '18 F350 with the rear Elocker, want to add the Truetrac to the front but they are not available for the Super 60. Very disappointed, would have thought they would have something available by now.

You’re in luck. Unles you have a F450 or F550 you dont have a true Dana Super 60 (256mm ring gear and 7,000 lb GAWR). You have the same axle that your 05 had - a high pinion reverse rotation Dana 60. It will have a 248mm ring gear and 35 spline inner axle shafts but it has larger axle tubes, etc than a vintage Dana 60. All of the popular differential carriers are avaliable, including air locker, elocker, detroit locker, and eaton truetrac.

I’ve been considering the same for off-road use, mostly mud.

The Dana Super 60 in 2018 runs the same carrier as the Dana 60 from 1956.

Just make sure you get the correct carrier break. So it should be a 4.10 and down carrier from truetrac.

Thank you everyone for the information, I had been corresponding with Eaton via online where they told me that nothing was available for my truck. I'll have to call them directly.

Next question. Currently have 3.55 gear ratio, was looking to go to 4.10 but searching around looks like I will only be able to go to 3.73 with my M275 rear. Do I have that correct?

Yes the m275 rear only has up to 3.73 gears available. You'll have to settle on that or hope tye aftermarket come out with 4.10s or 4.30s

I’d wait for the aftermarket to catch up. No way I’d bother swapping front and rear ring and pinions to go from 3.55 to 3.73. It’s just not worth it.

So back to the Truetrac... Can anyone shed any light on how much of an improvement it might make in low traction situations like snow or mud? Anyone try it on one of our trucks?

I agree. I'm going to try and find out when that may be. If it's going to be a while I might go ahead and put the Truetrac in and change the gears at a later time.

Had a Truetrac in my 05 and was very happy with it.

I put one in the rear of my 06 Powerstroke. It worked great. No noise, no adverse handling, and it is always working. Frankly I wish my 16 had one in the rear axle versus the oem elocker. The rear elocker is great when you need it to be locked, but the rest of the time it’s an open differential. With the torque of the 6.7, a Trutrac in the rear axle would be very helpful. As I have said in other threads I think the perfect setup for a Super Duty is a Trutrac in the rear axle and an Eaton Elocker in the front axle. I setup my 06 this way.

It looks like Strange makes an S-Trac for the 35 spline Dana 60 also. So that’s another helical option.
