When I did the SAS in my truck, the D44 HD that I put in had 3.54 gears in it, so I swapped the entire rear axle out for one that had a 3.55 rear (sterling 10.25 of course) since it had all new brakes on it and I just had it sitting around, so I'm not entirely sure of something.
I want to put my 4.11 gear back in the rear end because I bought another F250 (late 70s with same front end, not a high boy) with 4.11 gears that I can swap. But I took my ring gear off of my other carrier because my buddy was going to buy them and then changed his mind. So, will the 4.11 gear bolt to the carrier that the 3.55 is on? Or is the carrier different between the two?

 

The Sterling 10.25 does not have a carrier break, so yes, your 4.11 gears will fit your 3.55 carrier.

 

Ok thanks buddy!
