Should you get a heavy duty fan clutch?

I took a video today to help @machoheadgames figure out if his is working correctly. Figured I'd post here so people can compare.

cold start, revving to about 2300rpm until the fan clutch disengaged after approx 15 seconds.

Based on how far I'd get from my house before the Hayden stopped roaring, I'd guess this test would have taken a good two minutes.

Are you running the 22159 or 22160?

22160

I went with the 22159 for more idle lockup hopefully. Much like the 2791 it’s not listed for our tjs but is a direct fit severe duty clutch specd out for the v8 rams I believe. Maybe I’ll pick up a 22160 and see if I can tell the difference for science
