Perfecto 2 speed differential for Ford Model T
The Perfecto two speed rear axle was a planetary gear system that when engaged reduced the final drive ratio of the Model T from 3.6:1 to 5.5:1. this enabled the car to climb most hills in Ford standard top gear (downshifted into the Perfecto intermediate gear) as well as adding a "bull low" to the transmission. This was a useful modification for the Ford Model T and about 650,000 of the units were sold between 1920 and 1927.

I may not understand the feature "underdrive and overdrive by changing master gear and pinion." Do they mean you have to put the car on the hoist and get into the axle to swap out gear and, uh, other gear? The features list also says "change can be made at high rate of speed." Oh my head.
I want to know what on earth " Attractive proposition to live reliable people on state rights" means????
Looking for people to set up a distributorship?
pzak, you may be right. It's like a random word generator.
Rats, I've added more info on the installation. The differential has to be diassembled to install the kit, but once it's there, a pedal/level activates the gear system so it is easy to shift in and out..
