Scorpion Endurance Series Shaft Mount Rocker Arms are made for the most demanding endurance racing applications. This system creates optimal valve train performance and geometry by accurately positioning the rocker arm over the valve center line. The steel shaft functions as the fulcrum, which greatly increases rocker assembly stiffness and valve train stability.
Scorpion takes precision manufacturing to a whole new level with its new Endurance Series shaft mount rocker arms. These rockers were designed for professional circle track, dirt track, drag racing and offshore powerboat race engines. We believe they are the best shaft rockers available today and are built to perform at the top level, lap after lap, race after race. Plus, they are priced very competitively, and they’re made in America.
