Outer Limits 4x4 Board

just wanting to know without pulling it apart, what ratio is in my patrol, 4.2ltr petrol 1990 model auto,

3.9

thanks mate,

Could also be 4.1

Check the tag in the engine bay, the first digits are the diff ratio from factory.

^^

What he said

It will say HG41 or HG39

HG39, 3.9 ratio

i wondered what them codes where,

thanks guys

you wanna try 38" tyres on that diff ratio it's an experience!! Driving back from the watagans yesterday with a head wind.... i think i averaged about 40 litres per 100

yeah i bet, just chasing some 4.1's, at the moment

with the auto, i would go with 4.33 gears.

I'm biding my time and getting some 4.88's....... again

you will find that its the maverick's that usually have the ratio's that are " exceptions to the rule"
if its a 4.2 patrol auto it should have 3.9's , manual 4.1's
maverick manuals have 3.9's and 4.1's
maverick auto's likewise.

what does 37.9 mean, is it 37 devided by 9, = 4.11

yes

thats what i wanted to hear

My 89 TB42 auto Patrol was 3.9, my 93 TB42e auto Patrol was 4.1, friends 89 TB42 manual patrol was 3.9.

4.3 gears would be heaps better for your application as Patrolden said.
If you are lookin for those they are standard gears in a patrol fitted with RB30 (3 litre) petrol donk and manual gearbox.

Got a pair of 4.1's from a 1998 GU TD42 going cheap if your interested...
They have 210,000 klicks on them. They came out when 4.6's went in.
