Thread: LT95 T/F ratios Stg1/110/Isuzu

The 1.123 is the early Range Rover and Stage 1 ratio the Perenties are as others suggest 0.996.

It is the reason why Stage 1 4BD1 seem to be less of a slug when taking off from traffic lights, but run out of puff at motorway speeds.

I believe the Perentie vehicles all have the same transmission and transfer case gear ratios as follows:
4x4: HI 1.123:1, Diff ratio 3.54:1, and
6x6: HI 0.996:1, diff ratio 4.7:1.

The simple reasons were that ARMY did not want the 4x4 to be able to travel too fast, and for the 6x6 the gear ratio and top speed was linked more to start-up gradeability and overall maneuverability rather than highway speed: 95 Kph@3300 RPM. Some models had the fuel pump adjusted to give 105 KpH @ 3600 RPM.
Any spanners or greasers out there who can support or correct please?

Only 1 perentie 4x4 variant had 1.113 and that is the RFSV all the others have 0.996 as well as the 6x6.
