What axle ?

[f250power]

I've got an 03 7.3, 2 wheel drive. I know it has the base axle with 3.73 gears, just wondering what kind that is because I'm looking into getting a posi unit. I know it probably says it on it but don't feel like going down there.

it is a sterling but it is a 10.50 , the dualies have a 11.25 in them

sterling 10.50

the 10.25 was used in the older trucks
