This is about the same as the locker pump BS. The other model that has the locker pumps tell everyone to rob them from a TJ Rubicon. The TJ Rubicon folks rob them from the other platform. Most call that the Ranger style hub. If you dig around you can find them telling everyone to use the Warn 27 spline versions since they are stronger.
All I know for certain is the hub is stronger than you think and you really do NOT want it any stronger, trust me on that one. The breaks move away from the hub to the high dollar shit like the bearing hub and spindle and that sucks.
Are you saying the 27 spline warns I put on a bronco II in 2009 might have been the same part that a TJ manual hub kit used? If so I need to be excused so I can go kick myself for not having precognition and leaving those hubs that I only paid $75 for on a Bronco I sold for $1200.
I can't find a photo of them but I specifically remember them not having any Ford markings and looking just like the ones I see from the Warn TJ hub kits.
