Inside of the drivers door is a build sticker, just below where is says axle there will be two numbers or a letter and a number. Letter and number is Limited slip two numbers is standard rear end. Post the code and we can tell you the ratio.

Here's a link to an older request check post 6 for the codes

Where can I find out which rearend I have?

4N is 4.10 LIMITED SLIP is that good ratio

[LAW-DOG]

That would be the standard ratio for a F350 dully but lucky for you they did the option for limited slip.

Under axle on my sticker, it says F2. What does that mean?

Edit: Nevermind. Found that it shows limited slip 4.1.
