2007 Expy Limited-Slip 3.73?
 

Do the new expy's come with the LS 3.73 if you get the heavy duty tow package. I couldn't find this on Ford's web site.

I don't think so since they all have the traction control system now.

Thanks, I like that rear end. Is the new one just as heavy duty as the old 3.73LS?
