6 stud girdle kit for Yamaha 701/760 and Yamaha 1100/1200 ADA billet heads. Includes 6 stainless studs, 6 stainless washers, and 6 chrome acorn nuts. The only true girdle system. It does not bolt the cylinder to the cases, but sandwiches the cylinder between the head and the cases. Therefore, there is no pressure on the base of the cylinder. The threads are rolled for strength and not cut. Thread rolling compresses the material adding strength to the threads. Cutting threads leaves the root of the thread sharp, weakening the thread and making them easier to break.
We make these in-house in the USA from American made stainless steel. These do not rust and they do not break!
Exact availability date is unknow at this time. We are waiting on material and have been told it will not ship from the mill until mid-June. This is the 4th time the date has been extended, so we cannot even be sure that we will receive material.
For the time being, we have made a new girdle kit with larger diameter studs that are stepped down to fit through the base of the cylinder and the girdle holes in our billet heads. See the link below under Related Products,
