MJ9 Cyl. stud kit M8x162mm
With special threads, that are milled by hand, the studs are made of high quality tool-steel. They possess an extremely high tensile strength and hardness, while remaining flexible at all engine temperatures. The threads were modified to make to studs sit firmly in the engine case, once they are screwed in. This solves the problem of old engines that have an unduly high thread play. ‘MJ9+’ studs are suitable for slightly, ‘MJ9++’ studs for extremely worn out threads.
