I searched and searched but could not find a Sterling 11.5 either. I wanted to compare the weight capacity specs against the 10.5 for myself.
The only mention of it was on The Diesel Stop where one guy mentioned "the new Sterling 11.5".
I'm going to keep digging. Maybe this parts guy was all wet. I need to run down one of the truck mechanics at Ford!!!
Well I wont say hes all wet-just not sure what hes referring to-but theres is NO such thing as an 11.5 Sterling axle in a ford.
specifically speaking FORD and specifically comparing the Ford 10.5 Sterling axles used in F250/F350 Single Rear Wheel trucks-
99-05 identicle Sterling 10.5 axle
Beginning 2005 however, the Sterling 10.5 used in the F350SRW has larger 37 spline axle shafts. The F250 Sterling 10.5 has 35 spline shafts. I havnt capicity specs, I assume larger shafts would increas numbers.
2007-2010 Bearing change
2011 + 10.50 w/ 37 Spline (not sure what changed/ rebuild parts different?)

page 19 of pdf file (page 73 of document) shows rating/axles used.
There are some other variations (pinion gear count etc) but basically, '05 up F350 has stronger higher rated rear axle though its still a Sterling 10.5.
FYI The Dual Rear Wheel F350up is a different truck-coming with a dana80 11.25 (however there ARE some F350 DRW's with smaller 5.4L gas engine that have the Sterling 10.5)
