PRW PQx Series Aluminum Shaft Rocker Arms

PRW Industries offers PQx Series aluminum shaft rocker arms for a variety of engine applications. 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.

Once the initial Sportsman-style shaft rocker systems became acceptable to the customer base, the PRW group immediately began moving forward with more aggressive race engine designs in 2024 custom aluminum formulas. They are specific to manufacturer’s cylinder heads and specifications that fit the more popular OEM and aftermarket cylinder heads. The rocker arm assemblies available are the result of a decade-long PRW commitment to pedestal-shaft rocker arm system evolution.
