I was not saying the themostat was a much but for how cheap it is it cant hurt to get one. I know alot of guys on here use the 160 degree stat but its just up to the build and how good your cooling system is working. I was curious about the half shafts when they start to fail. I am sure it depends on if you track alot or not and how you are hooking up.
