F550 Locker?
Has anyone got any information a 41 spline M300 locker yet? I have been emailing both Eaton and ARB and neither seems to have any desire to build a locker.
I am in dire need of a locker in my 550. Even in 4wheel drive I have constantly got stuck this winter in snow and ice. My truck is a service truck and goes off highway almost daily. We have thought about tire chains in the interim but you cannot run those on the highway daily. They must be put on once we arrive at the jobsite.
Thanks.

Put an oem Dana limited slip in the rear and an Eaton Truetrac up front.

I believe the factory limited slip in rear is 37 spline not 41 spline. It's for SRW m300 I believe. I have DRW 41 spline m300. When I special ordered the truck they said limited slip was only with SRW m300.
Is the front axle a super 60?
Thanks

We have only 4k miles on the truck now and it cost nearly $80k with all outfitting done so we would definately not go that route at this point. I appreciate the simplicity of the idea however, it just wouldnt work for this rig.

So you can spin the truck around on ice, break shafts and lose a warranty? Seems like a terrible idea.

The 450PU comes with a limited slip rear, and the axle is the same for the 450PU, CC, and 550CC. So if you want to spend the money, a factory LS is available.
Id just put a Torq lock in the front. $500 in parts and you can install it yourself. Part #TL-16035-TOR

Since you have $80 Grand in the truck already, you can get a true locker from DBL Design if it is that important. Not going to be cheap though. >> DBL Design

This Q and A claims the 350 and 450 are 37 spline. So that is why we assumed the 550 is the only one with 41 splines and why Ford said there was no limited slip for 550
Anyone know what the deal is here?
