Considering buying a friend's 2012 F-150, but I'd like to get a Trutrac for boat ramp use. How do I identify which one I need? Door jamb sticker says the axle is 19 – 3.55 Non-LS.

Can anyone point me in the right direction?

 

You will need to get the code off the axle tag itself to determine the size and type.

 

glc is correct. This will tell you the additional information.
