I want to raise the gearing on my Series I,II,III. Overdrives are getting hard to come by and expensive, what alternatives are there?
We make a High Ratio Transfer Case Kit. This has the effect of permanently raising high range by 32% and leaves low range ratio unchanged. This is as strong and quiet as the original, cost effective and can be used with the PTO. It does not necessitate the re-calibration of the Speedo. We are only able to supply this in kit form.
