Diff cooler will help. I have one. Plus the OS Giken diff. Diff cooler will set you back about a grand. I also have a diff temp gauge. It takes about 20 minutes to see the needle move off of 120F at 60 mph. The highest I have seen without the diff cooler on is 275F. The diff cooler will keep the temps around 175F or less. Depending on outside temp. My diff cooler is wired with 2 switches. One for the pump, and the other one for the fan.
