Has anyone any clever ideas for greatly altering the gear ratios on a
Range Rover both lower and higher.
I could use a r380 gearbox with the 230 transfer case but the ratios
are not right for me. Could add a new set of lower gears to increase
the low ratio and then an overdrive to increase the high ratio but
this seems complicated. Any better ways of doing this. A new type of
transfer case maybe..............

Thanks

You could use the 230 transferbox from a 110 which has lower gearing than
the 90 or Disco/RR. Alternatively you could stick 4.7 diffs in the axles -
what do you want to achieve?

Thanks for the reply. Good idea to change the diffs except that I
would have lost my higher gearing. I am going through the ways of
increasing the low range
gearing and also making the top gear high range higher.

Follow up to my last message

I have just had a thought. If suppose a three speed transfer case
existed like a Klune extreme but remember three speed. The case would
go between the r380 gearbox and the lt230 transfer case. Then one of
the three speeds would be 1:1,
another would be say 2:1 reduction thus greatly lowering your crawl
speed and lastly the third speed would be say .75:1 greatly improving
highway cruising.

I see what you are after now. There is a device called an underdrive that
when selected makes lowbox twice as low, but does not affect high. This
means you could afford to raise the high gearing conventionally such as with
3.1 diffs whilst still having very low gearing for off-road use.
