are those OEM mopar sensors on that link? Also how did you get the discount to get a set of 4 for $208? I have a 2013 ram on the way and have been looking into sensors too. They list at 100 bucks each in canada, so i was going to buy them in the states anyway as i am close to the boarder. What year truck do you have? i want a second set for when i buy aftermarket wheels but trying not to spend 300 to 400 bucks unless i have too. My tire guy said the mopar system does not always work well with aftermarket sensors. I have not had any vehicles with tire pressure sensors on them so this is all new to me.
