Q: I’ve heard that it is best to go with a “trimmed down” Duramax fan on the 6.5 instead of the 21″ fan you sell, because sagging motor mounts will cause the fan to rub on the shroud. A: If you have bad motor mounts you had better replace them asap for more reason then just a rubbing fan!!!

A couple minutes work is well worth the benefit! Q: I have a set of your gauges, what are the maximum boost, EGT and tranny temps I shou
