F450 dana 80 rear end, I am looking to put a dana 80 in my F550 so I can have 3.73 gears.

I would like to keep the F550 rear but there seems to be no realistc soulotion for 3.73 and a locker for the spicer s110/s135 axel

thanks I see Gears-R-us. they want $895.

when you changed your F550 to 3.73 did you change the carrier also.

I was looking on roadranger.com and they had every ratio you could think of from 6.72 to 2.93 for that rear, but the carrier was different ever few ratio steps.
