Rear Axle 4.10 or 4.30?

I have a 2013 crewmax 5.7 with TRD offroad and Tow package, when I do a vin lookup it says 4.10 and shows the Tow Package. but when I looked at the original window sticker it shows the 4.30 in the tow package. I need to replace the rear end and was shopping for a 4.10 because of the vin lookup, I purchased a 4.30 based on the window sticker ( installing tomorrow ), hopefully I got the right one. not certain which to believe but leaning toward the sticker? Ill try a spin test I guess.

 

If you have the tow package, I believe you have the 4.30.

 

IIRC, the 4.6 with tow package is 4.10. The 5.7 has 4.30.

 

Thanks!
I think so also, I did see some posts that said tow package gets the 4.30 but also saw some that implied that was only for 2014+, and saw some like https://www.tundras.com/threads/tow-package-rear-end-question.57424/#post-1511454 that seemed to trust the VIN lookup rather than having a tow package, also when I would call around looking for a rear end they all wanted to go by the VIN lookup, luckily I still had the window sticker!

 

I thought the 4.30 was part of the tow package since 2007 but maybe I'm wrong.
