There is more room in the 3rd brake light for larger bulbs (more LEDs). Plus, the bulbs you linked above are not CANBUS ready, so they will most likely trip error messages on your EVIC display (bulb out warnings).
As I posted in other LED threads, I used these for the license plate lights.

No errors and very bright. Used a third for the upper glove box light (replaced the incandescent bulb there). Not sure why FCA provided our trucks with the option of an upgraded LED light interior, then cheaped out on one bulb for the upper glove box. The fourth bulb is my spare, in case any of the other three decide to die.
Used something like this for my third brake light, no errors on EVIC, nice and very bright.

And lastly, a cousin to the above bulb, but white for the cargo lights.

Very bright, very nice, and match the license plate lights in color (5000k-6000k white, no blue tint).
You definitely want CANBUS ready bulbs, unless you want to deal with bulb out warnings.
