What does your run rpm on the highway? I was talking to chris at LSX about that today and they couldnt recal.
2500 at 70 on a 30'' tire 22s)
This should help select a gear. It shows the RPM your engine would be at in 3rd (1:1) at 65mph. Just multiply the RPM for the tire and gear combo by 0.696 (OD ratio)
