I saw this ad in kitplanes..  They are using a C6 planetary gear setup
for a Subaru, and advertise that a Mazda unit is coming.  It looks like
they are using a custom cast housing.

It has been around for several years. John Vlake is on here
if you wish to ask some questions.


I like the cast bell housing, the shrink fit and silver soldered
input shaft to the pinion gear. I am not so fond of the angular
contact bearings and short prop shaft and close mounted prop shaft
bearings as it leads to excess weight IMHO. However that type of
design is common in front drive and independent rear drive  car
axles. In those cases the car designer has little choice due
to length considerations. Some of these car parts could or
may be used.

I much prefer the Ross type design with large diameter hollow
prop shaft and widely spaced needle bearings. No beating the
lite weight and low cost of needle bearings for this application.
So far nobody has matched the lite 35 pound weight of the Ross
PSRU yet. Some Ross's have been in use for 20 or 30 years.
