3.91s have been our gear of choice forever. So hiway RPMs has always been something we keep an eye on. 3,000 has been the dividing line so to speak. Staying there abouts or under is preferable and the farther over that you get and the longer you stay there, then the more pounding you are doing to the engine.





I've always used 3,000 rpm as the dividing line as well. No testing, data, or science, just feels about right.
