So which outlander has the lowest gear reduction?

A Lil help here guys. I have not been able to find a definite answer to which gear reduction came factory on my 2015 800 xmr and my wife’s 2016 570 xmr.I’ve seen statements of 14% reduction in hi answer some say it’s in low that got the reduction. On the 570 I can’t get a definite answer rather it has one at all.

I keep seeing post saying the 1k 6×6 comes with a 28% reduction in low and 14% in hi. If that’s the case, could I use the parts frof the 6×6 Trans to get the 28% reduction in my 800 and the 570?
