That's because the gearless locker that was made for the suzukis were only prototypes, not production units. They didn't put them into production, because out of 250 units, all but 2 had fatal problems. Currently the only mechanical locker Brent will sell, is the Detroit E Z Locker, because from what he has told me, since Richmond Gear bought out Powertrax...the parent company for Lock-Right...they are very problematic now. But the E Z Locker is a very dependable unit. The only thing that is likely to cause you any grief about the way the locker works, is if you have even a slightly bent housing. A truss or a heavier housing from Sky Manufacturing would take care of that problem.
Hope that helps.
