Hello,

I'm writing update for this if someone else is interested in 4x2 parts.

I have tested them now 8000km. with reduction maybe 30km, opened the cases and all looks good.

Driving noice reduced significantly, no need for ear protection at our cruising speed 80-83km/h (GPS). Of course cabin is also sound proofed, which it was already before changing the gearing. Original speedo shows more than 10km/h less, I don't know how to compensate it, for me it is not important.

Fuel consumption for our 4000kg and 3.1m high setup is ~14l / 100kms (including chinese diesel heater for few hours) and the car drives well small uphills too with 5th gear. The Car has intercooler and the pump is tuned for it. We did the test drive in finnish Lapland and Norway.

Future tells how long these gears will last. We are finally heading to Africa in the end of this year.
