Since The one-way bearing is required for 2-speed functionality, the only way this will work is if you are converting your tranny to a single speed. How big is the gear you are working with? You can most likely get a large pinion gear from Mike, or Stock Drive Products with a hub and set screw that would facilitate this. You would need to grind some material off the shaft for the set screw to hold properly. Or, if you're feeling really ambitious, you could bore all the way through the hub and shaft to allow a pin for support on both sides of the gear/hub.

Personally, I would stick with the 2-speed and move to a smaller brake servo.
