Steve : The ring gear has 74 teeth and the sun gear, on th= e input shaft, has 34 teeth. 74/34 =3D 2.176 ratio

The ratio of 2.17= 6 stays the same with a 6 planetary although the planet set is much stronge= r and has a steel housing that holds the planets.
The 4-pin planetary wh= ich the redrives was manufactured earlier days has an aluminium body.
Th= is is the set/up where the planetary is held stationary and the ring gear i= s the output

There is now a new version 6 planetary that fits in the= 12 lug slots which has a steel casing
