APE Hayabusa Countershaft Case Stud Kit

APE, in conjunction with DME's Skip Gladstone, has developed a stud kit that holds the cases together behind the countershaft. Skip contacted APE after breaking two sets of engine cases in this location. The advantage of the stud over the oem bolt is that a bolt can not use all of the thread in the case or it bottoms out. APE studs go in all the way to the bottom using all of the case thread. Also, studs are not removed every time the cases come apart.

The stud is manufactured the same way we do our world famous cylinder studs. Same heat treat and threads rolled after heat treat. Comes with a special APE nut. The high tensile strength does not loosen and allow the case to flex.
Why take the chance. The cases can not be repaired when they break here.
