New to Forum. Thank God I found you folks..and now the questions

[Harvey62]

I own a '62 IH C-20 4x4 (3 sp, 304, 97K miles). It is in pretty good shape, but it's geared like a D9 CAT. Top speed is around 55 MPH and at that it sounds like a jet airliner trying to take off. I want to tame it down a bit and get the vehicle to be more of a daily/weekly driver. I was born the same year as this truck so a quieter, smoother drive is more my speed. 

 

I need some advice: Do I need to change the gears in both the trans and the rear differential? Can I leave the front differential alone since I would only use it on rare occasion (like cutting firewood, or the freak snowstorm)?

 

Thanks in advance.

Follow-up: I would love suggestions on the best parts sources for my '62.

You just need to change both front and rear differential gear ratio. If you only change the rear and go to use the front, things WILL break. Mike
