I will be getting one soon and would like to hear some input from anyone that is running one.

 

I put one in a '01 Grizzly with 27" tires. It worked as advertised, you can go in a straight line through just about any natural obstacle. In mine, the effort required to turn the front end prevented "relaxed" riding...ever. I took it out after a couple of months. Made plowing small driveways (<40') a nightmare. Other than the amount of effort required to turn, I never had a mechanical problem related to the locker. Plan on an afternoon for install, a little less if you use air tools.
