In 2017, the PRW product development team recognized the need for an affordable collection of shaft rocker systems that would cost about the same as a set of roller rockers, new rocker arm studs and a stud girdle. These assemblies were designed with the sportsman racer in mind, and provided for longer pivot length rockers, various rocker ratios, adjustable stand heights, and implemented simple installations with minimal valve adjustments throughout the racing season.
