31 Splines Question

[sailsmen]

I am happy with what's in sig - my 31 Ford Spline Axles & Detroit Truetrac, 4:10 Ford Racing Gears

So as I research the c clip eliminators it seems like it depends on the install and the brand used. They seem to add a safety benefit too. But you all are saying that that's not true? I see some say they leak but a lot of others say they use them on their daily drivers without any issue. Anyway, I like the idea of a safety factor, but not the whole leaking bit... And those who are saying not to get it and the Detroit locker have personal experience with these items?

"C" clip eliminators do provide some security but IMHO that is overridden by the leaking or potential for leaking. A majority say don't use them on a street driven vehicle.

DO NOT get any type of locking rear. I don't know how much clearer we can make this, unless you and your passengers like to hop around corners with a lot of banging noises. My son had a Camaro that had a locking rear - for the track - and it was horrible, just horrible driving in anything but a straight line.

Well I switched to 31 spline axles and I went with the Auburn ected diff. That way it will be a true limited diff for my daily driving and I'm able to switch to locked when I want while driving. Seems to be the true best of both worlds. I had time to research it and those who race say the ected is a very good diff. Anyway, thanks everyone for warning me about the locker.

I’m hard as hell on mine with a manual trans and my plain Jane Ford Racing 31 spline axles and diff are just fine..

Might I also suggest a diff stud kit and a solid pinion spacer.

+1 on the stud kit & solid space. I'd also recommend a new cover with bearing supports.

Yes, I'm getting a reinforced cover just as you suggested in my question to you about 4.10 gears. It has the ability to add oil without taking off the the cover. Looks like one nice piece of equipment. Now, the stud kit and solid space, not sure about that. Geeze, things just keep getting piled on. Tis the life I suppose.

The solid spacer and the stud kit are relatively cheap and pretty much sums it up for extras after the diff and axles.

Yeah, I realize that now. Got them ordered too.

I strongly disagree with a few suggestions on here:

1) the Eaton Detroit Trutrac is what you want - forget about any differentials with clutches (unless you want to replace the clutches on a regular basis).

I have been driving my MM for many years with a Detroit locker. It took a while to get used to it, but I have not had any problem with it - some minor noise issues and occasional clanging. People who hear it think it is breaking or coming apart. It has never "hopped around" and it does not "chirp and hop on turns" - that's what happens with a spool!

I probably should have gone with the Trutrac, but I wanted the strongest differential available - the people at Eaton will recommend the Trutrac.

2) a solid spacer makes replacing the pinion seal a simple R&R of the flange, without affecting the pinion preload

3) 31 spline shafts are a minimum for performance use - 28 spline are not even to be considered. Ford went with 31 spline shafts with the Panther platform from 2005 and up

4) studs for the main caps and an aluminum cover with pre-load bolts can only help - get them

5) 4.10 gears are the best for what you want

6) C-clip eliminators are for racing only - not for street driving with a daily driver - if you want a safer way to go, have the axle ends replaced with 9" ends (and custom axle shafts) -- 9" Ford axle tube housing ends - the big bearing "New Style Torino ends" (3.150" o.d.)

Moser has a nice "Hobby Stock" 33 spline package (and probably Strange does too)
