Is it just me, or does no one (reputable) make an upgraded aluminum thermostat housing to for the 3.6L Ram’s?

Dorman has a few for the 3.6L engines, but there when I look at the specs, they don’t list the RAM (just Chrysler 300s, etc).

Also, what is a good thermostat you guys would recommend? Even if the upgraded aluminum housing comes with a Thermostat already installed, I’d probably remove it and install a better, more tried tested and true one for less worries.

I "think" my 2014 came with aluminum from the factory. I replaced the bleeder screw with a brass one and could have sworn it was aluminum.

I used an amazon aluminum housing for a Durango 902-852 and swapped the wax motor/spring out for a Mahle T123795 Grand Caravan one. Works great no hose cutting or anything. I also did a amazon Aluminum crossover tube that the thermostat bolts to!

Mahle is who makes the factory thermostat it comes with the Chrysler symbol ground down and says BEHR.

The Grand Caravan Mahle seems to be out of stock at most place a Mahle TI23695 for a Grand Cherokee 3.6 could be used if just taking the wax motor and spring out to swap into aluminum.
