Overview

PRW Rocker Arm Shaft Stands

PRW Power rocker arm shaft stands are components that hold rocker arms on a central shaft instead of individual studs, providing greater rigidity and stability in high performance engines. These stands are made from strong billet 7075 aluminum and are designed to reduce flex, improve alignment, and ensure proper rocker arm function during high-RPM operation. They're crucial for high-horsepower applications, especially those involving aggressive engine builds, high-lift camshafts, and racing.

Function and benefits:

* Increased rigidity: The reinforced shaft-mount design eliminates the flex associated with single-stud mounts, allowing the system to handle higher loads.
* Improved stability: By holding the rocker arms in a fixed, parallel position on the shaft, the stands ensure precise valve motion and consistency.
* Enhanced durability: They are built for high-RPM and high-pressure applications where traditional rocker systems might fail.
* Valvetrain geometry: They maintain proper rocker arm geometry and alignment, which is essential for a well-performing engine.

How they are used:

* Shaft-mounted system: Unlike standard rocker arms that mount on individual pushrod guide studs, shaft-mount rockers are mounted as a set onto a rigid steel shaft.
* Stand components: The "stands" or "pedestals" are the parts that are bolted to the cylinder head and provide a mounting point for the shaft itself.
* Installation: Proper installation is critical and involves checking the roller's sweep across the valve tip to ensure it is aligned correctly.
