A question about air dam

[Zuto]

Hi guys, I'm searching 2014 Ram 2500 & 3500
and I found a difference about the air dam, see pic below:






As you can see, these are same 2014 Ram 2500, but the air dams have 2 holes and 3 holes...

can someone explain their specification?

tks!!

That is correct, Ram uses a different air dam for the Hemi powered and cummins powered trucks, they also have a different model air dam for the power wagons. Per 2013 had different styles for 2x4 and 4x4 trucks as well.
