I've been converting these hubs for a while. I've had alot of positive feedback on them ppl like my turned down hubs better then the factory hubs. I hav alot of time turning them down.I taper them machine the wheel mounting ring to press on its self it under a load then back on the lathe. I run them on the lathe at hi speeds to make sure they true.there 1/4 or .250 thicker at the lockout mount. when u lay them side by side with factory hubs there almost the same other then mine r thicker were u need it and they don't run out like factory..tell me what u think Eddie 8503824209
