2002 International 4300 still 466

Currently running 5.57 gear ratio. Truck was designed more for fire trails. RPM’s are near maxed at 73mph.

Im running 10-22.5 tires with overdrive tranny .78

Thinking of changing up the gearing for lower rpms at 73mph

any suggestions?

i don’t do a lot of mountains but some when going cross country.
