S 125 N
3.55 10 2 6 H16
and in the door jam reads axle- 39 i`m assuming that i have 3.55 gears...
so i have this other truck, a 91 F-250 and i has a posi rear, i`ve been thinking about swaping them, so today crawled under to get the tag off the rear.. it reads....
2 V107L
3L55 102 OK23

tag in the door jam reads, B9 i`m geussing that the 3L55 means 3.55 gears??? if they both have the same ratio i`m swap`n the rears sunday....

Yes, the 3L55 means 3.55 Limited slip. If it doesn't have the "L" it is an open differential.

If they are both 10.25 Sterling axles they are the same, the difference will be in the springs.

See if this helps out a bit...

I went through this when I was deciphering out a tag, on an axle that I had sold. Attached below is an explanation of the tag pictured...

S125N
S = Sterling Axle
125 = Model Numer
N = Revision Number

355 102 7A21
3.55 = Gear ratio
Open Differential (An "L" here would mean limited slip - the one below is not)
102 = Ring gear size (10.25")
7 = Year made (1997)
A = Month made (January)
21 = Date made
