stock gears dbl cab trd 3.4?

My truck is not in my possession at the moment so I can't look on the door for the code. I searched a bit but is a pain on my phone! On a 03' dbl cab trd 4x4 auto the stock gears are 4.10 correct.....I blew my rear diff last week and am have a complete regear done, I run 285's so I'm going with 4.56. Was thinking 4.88's but don't wanna over gear as it sees a lot of highway miles too. Any help would be appreciated.

The factory final gear ratio on a 2003 4X4 DC V6 base model was 3.91.

You got 4.10 gearing with either the e-locker or bigger tire options.

 

Thanks guys, I ended up getting the code off the door late last night. 4.10 thanks....
