Is it possible to change the ratio of a KPG25 gearbox.


Im wondering if its possible to convert a 5.2 to a 4.2 by simply swapping out the pinion and planetary gears. Is the outer ring gear the same in both ratios?

You have to change the pinion,planets and gear carrier to change a ratio in a planetary drive.
