Does anyone know the differences between a Dana 50 under the front of an Excursion and a Dana 60 under the F350 ? They look identical to me from the outside

 

a dana 50 uses a dana 60 housing with dana 44 inners pretty much smaller bearings axle shafts etc etc.

true dana 60 is just a dana 60. full size everything. much better choice than a dana 50. but if you dont really need or cant afford a nice 60, a 50 has a thicker and stronger housing than a 44 and theyre very cheap and easy to find

ring gear diameter is only 9" on a 50 and 9.75" on A 60

1.65" vs 1.35" pinion shaft diameter

35 spline vs 30 spline

just to name a few. hope it helps!

 

Can you swap out the internals ?

 

i dont believe so. i believe a dana 50 has an "almost" identical housing as a 60. but i dont believe theyre the same. you could call an axle tubing shop and ask them for more details im not really sure on that. but i dont think you can. i believe the differentials are different on a 50 than both a 60 and a 44 i think it is right inbetween both of them for ring and pinion size. i know there are several companies who are selling 35 spline kits for them as well and gear options are starting to become more readily available

 

Are you sure you do not have a dana 60... 90% of the excursions came factory with the D60...

 

No.....I am not sure.....but everyone says they are 50's in the Ex's......looks exactly like a 60 but smaller axles 35 vs 30 spline. How do you know 90% of Ex's came with 60's ?
That's not what I am hearing

 

Lol... This is what I have always been told, the Excursions came with Dana 60's from the factory.

I'll do some checking.

 

im pretty sure excursions came with 50's. my buddy straight axled his silverado with a 50 that came from an excursion. as with all dana axles look at the bottom right corner of the front of the bottom and it should be stamped with a d35, d44, d50, d60, d70 etc etc etc

 

The 5.4L's probably came with 50's. The D60 is probably in all Diesel and V10 Excursions...That would be my guess.

 

From what I am reading the 50's in Ex's have the same ring and pinion size as a 60 but have smaller axle shafts. Apparently they hold up well even with larger tires and moderate wheeling. Not much out there aftermarket wise for them though.....ARB or powertraxx is about it for lockers
