Gearing for a kzj70

[kzj 70]

hello

does any one know the correct ratio my kzj70 diffs will have?

I am running 35s, i want to put the gearing back to standard by changing the ring and pinion or is they another way i can change it with out spend 1000s ? please let me know

I have a few spare sets of diffs at 4.88 ratio ? and was thinking of swopping them over if it would be worth it? i have also seen 5.29? available


any help appreciated

diff ratio

hi, your kzj 70 comes factory fitted with 4.56 gear ratio. With r150 gearbox.
I've tried a few ratio & tyre sizes. So far i've been running 4.88 ratio with 33 inch tyres gives you about the same ratio as 31inch tyres on 4.56 ratio.(factory setup) Any larger the tyres as in you're case, really depends what you do. if you're serious offorading then you'll probably want 5.29. If you're doing roadtrips etc then maybe you'll prefere the 4.88, which with 35inch tyres will have a 10 percent higher ratio than factory
setup.
Another option you have is to change the gearbox from a 2.5 turbo landcruiser^prado which is the r151 lower gearing and 4/88.
I've just sold my KZJ73 VX 1995, which I had with R150 gearbox
4.88 diffs and 33 inch tyres and I found it perfect for where
i live, for towing and offroad trips to morroco.
Just bought a KZJ77 which still has 4.56 diffs and running 33 inchs and the gearing is to high for my liking.
Either I'll fit 4.88 diffs again as i've got a rear diff but havent got a front one or i might experiment and pop the R151 gearbox I've got here and see. Will be fitting ARB lockers on this one.
Have you got any spare front diffs by any chance 4.88.
