Anybody ever have a problem with these? Last trip out my nut skipped all of the threads on the can and essentially unloaded the whole spring. Probably my fault in that the pinch bolt was not tight enough. Anyway, I bought a replacement and when I went to put it on it was not going on very easily. The threads from the nut are not meshing with the threads on the can. Does anyone know if there are different thread pitches for these adjuster nuts? Maybe different from the pre run shock series to the race? You can kind of see from my pictures what I mean.
