LSM met that need with the introduction of the first viable titanium valve spring. After this first LSM continued to innovate to meet the needs of the racing industry. LSM started grinding camshafts to take advantage of the new valvespring. The next innovation was to increase the journal size to 55mm. This allowed for a stiffer valvetrain and better geometry.
