What kind of rpm are you turning at highway speeds with that gear combo? The .64 will definitely drop your top gear rpms, but be aware that it is a true overdrive gear. You will really feel the rpm drop and power loss when you shift from 4th to 5th. It may be a just what you are looking for, but be aware that it will definitely turn your 5 speed transmission into a 4 speed with overdrive.
