Friends and members need some input on diff gear ratio, currently OEM set of 1986 model HJ60 which i suppose runs on 3.78:1 correct me if i'm wrong have installed 35" maxxis tires on 15" rims. I'm not into hardcore off-roading and will use the truck as a expedition vehicle with some camping gears and which will involve hill drives also planing a trip to Leh and Laddakh northern part of India which is one of the highest drive-able mountain peak which stands at 13000 ft from sea level. now want help in deciding differential gear size.
1) do i need to upgrade?
2) if yes what would be the ideal upgrade?
please explain in lay man terms as my IQ is bit low
