summit has the 180 stat vfor the 05 dakota part number is 10170 it say its only for the 5.9/5.2 but it fits the 4.7 also

 

The part # is 10177. This is new from Jet Performance and is specifically for the 3.7 and 4.7. This is fact because I ordered direct from Jet and already installed it. Perfect fit. Since I also had the StageII chip ready to install, I did both at the same time. Reconnected neg. terminal, did the 3 X start/stop and I was good to go. Big difference in throttle response, crisp shifting. and I can light up the tires where I couldn't before.

 

excellent, i was a work when i was looking into stat number. sorry for the wrong info. i also have the jet 2 chip. but i put the stat from my full size in, now i am gonna get the matching one for my chip. for my 05

 

The Stant superstat also works, I just used my dremel to grind out a half moon to line up the rubber gasket. No leaks or any problems, just cooler temps.
