@BobT thanks, I have the same trany on my 2wd and it is awesome, they definitely help cooling the motor a bit which is exactly why I want to get them for my 4x4.
The set up I use gives me no heat problems but I always try to stay on the safe side and keep things as cool as possible. Specially with summer fast approaching.
One of my bash spots in the desert sees ground Temps as high as 130 mid summer. Which translates to the electronics getting hot just sitting there with the truck off. Any bit of advantage in keeping things cooler I'm gonna try.
If this heatsink works that would be awesome, coupled with a 40mm heatsink (recommendations welcomed) and fan on the motor plus maybe an aluminum motor mount (since the motor/motor plate make direct contact with it I'm guessing it will wick heat away) should keep my motor well below 120 all day
