I've seen them before mentioned in magazines, but I haven't seen any write ups. The hard core guys probably don't use them (rock crawlers) since they could probably tear down an axle in a half hour (and they don't want to weaken their vehicle in any way). It seems like a good idea for the occasional aggressive trail use. Warn has created a "weak link" in the front axle that is easy to replace. Without this item, the next weak link is far more difficult to swap. You need the Warn manual hubs to use the fuse.
