Probably would be considered more of a hill(s) than a grade. Still the low end better with the Rhodes than stock still pulls same on top but I don't go beyond 5500. You know the feeling is different when climbing hills or grades and you don"t get that sinking gas peddle feeling. They also are more quite on cold starts, lifter clatter is not noticable after about 2000rpm.
