In racing, the most stable rocker system you can get are shaft mount rockers. Instead of being on a stud or bolt that is prone to deflection, a shaft mount rocker uses a large billet stand that locks all the rockers together. On top of that are the rockers are then supported by two bolts that hold the rocker to the stand. This allows the rocker to articulate properly during operation, but virtually eliminates side-to-side movement
