Re: Difference in Hiway RPM-3.73 to 3.42
I don't know the RPM drop and you know that won't be huge. But I do know, or feel, 3.42s are a sweet spot for retaining the grunt of lower gears while giving the best hiway results. 3.42s will be best for final straight drive while also working well with O/D if you go that route later. Lower number ratios are too high for O/D if you ask me
