The gears will feel a little shorted though but bang for buck you would love it. In 5th you might see 200rpm increase in cruising speed which, if your running bigger tyres will put you back in your Boost sweet spot. They will give your car new life day to day.

In low range it will be a little punchier too and your engine braking will improve. It should improve just enough. It's about drivability. I think the reduction gears would give you the sh1ts in the Vic High country the rest of the time.
Thanks Daz, yeah it's a 5 speed. I turn the gas off and the A/C on, which makes a small difference, but not enough. I'll look into it when I get home from work. So changing the ratio will only affect 4wd ? Not 2wd ? Would it tow better as well ?
