Default 2003 rear end

I have a 2003, 4.6 liter XLT automatic. What is the standard size rear end size that came in F-150's for that year. I want to pull a trailer and I have no way of knowing the rear end gear size. Thanks for your help!

What's your axle code on the data sticker inside the driver door? Most common is 3:55LS

18 — 3.08, non-limited slip
19 — 3.55, non-limited slip
24 — 3.54, limited slip
26 — 3.73, non-limited slip
27 — 3.31, non-limited slip
B5 — 4.10, limited slip
B6 — 3.73, limited slip
H9 — 3.55, limited slip
