This seems interesting. I was thinking of converting one of my Savages to run without a transmission. Didn't really want a center diff neither as I would like to keep it's wheelie ability. I was thinking of locking the center diff but that would put a lot of strain on the front and rear diff. Something like this slipper would work very well for what I had in mind as long as it is durable enough. Would love to hear some input on it.
