The Stovebolt Site Forums The Parking Lot Big Bolts Timken 2spd Rear/Dana S110 similarities

Since I have a Dana S110 sitting around, originally acquired with the idea of putting in my 54 6500 (abandoned the idea) I’ve compared the two some and have been thinking…

The axle shafts in them are not the same at all. Not in length, diameter, spline count or hub mount.
The Timken has according to what I’ve read 1 11/16 diameter axle shafts. Not sure if they are equal lengths on each side but they are probably around 34in long.
The timken and Dana S110 have very similar pumpkin sizes. The bolt pattern however is different, but maybe the Timken housing could be redrilled for the Dana s110 pumpkin?
The S110 has 37, or 40in axle shafts, and is 1.70 roughly in diameter.
So basically my wild idea is… would it be possible to combine the two with some custom axle shafts that would fit in the Timken original hubs on one end and hook into the S110 gears on the other?

Interested to hear what people think who know more about this subject than I do.

There are places that could fabricate custom axles to fit whatever you need. The only rub would be if the splined end is bigger than the hub end. You'd need full specs on each axle.

The Eaton two speed 17221 rear axle was available on a variety of Chevy C60 sized trucks for many years. From what I can tell, it takes the RS404 ring and pinion. Available in any ratio you'd like and brand new for $340 all day long, those cheap gears make me wish I had the Eaton axle under this rig versus the T170 which is more difficult to get parts for it.

Turns out it’s actually a Timken not an Eaton. I think it’s an E300
