What gears do I have

[Rokhound]

Ok I think I have asked these before. I pulled the front diff cover off and I have no clue what gear I have and these number mean nothing to me so could some one tell me what these number mean.

 

The numbers are 9 1490 Dana D42701 P82049 3911 145

then the numbers on the u clip things are the passenger side is 317 c35

and the driver side is 317 c44

 

What the hec does all this mean please?

3.54s

The 39 is the number of teeth on the ring gear and the 11 is the number of teeth on the pinion gear.

I think the 3911 is Ring/Pinion gear tooth combination 39-ring/11-pinion which gives you a 3.55:1 axle ratio.

 

OOPS too late!!!
