NEW for Subaru Owners -Geared Drives Gearbox
with Centrifugal Clutch and Flywheel Assembly
as a Retrofit for Eggenfellner Subaru 4 & 6 Cylinder Engines

We have listened to you and have a solution!  Designed as a retrofit for Eggenfellner engine packages, this zero offset PSRU was designed to bolt on to your existing engine mounting plate with a minimum of modification.  Same thrust line, same length, starter remains in same location.  This PSRU RESOLVES the thrumming of torsional vibrations by means of our custom automatic centrifugal clutch, (just like our original unit) improves your engines performance in the air by multiplying torque to the prop!  This double reduction redrive has it's own oil pump and filtration system and the gear ratios can be changed without removing the drive from the engine!  Prototype unit on an RV-9A (Larry Perryman, Conroe, Texas) picked up 10-15 mph with this unit and utilizing a hydraulic constant speed prop.  This was swinging a huge prop, so we expect an even better report from him once he has a smaller diameter prop installed. This unit will easily adapt by means of our removable mounting plate for use on other engines. More information...

New PSRU currently being developed for V6 engines and others up to 250 HP

Also in development is a brand new PSRU designed to be smaller and lighter for use on engines in the 150-200 HP range. 
This redrive will also have all of the same features as our original PSRU in a smaller package and will also be housed in a CNC machined billet aluminum case!  Do the research and dare to compare, our PSRUs are the best on the market!
