Roller rocker arm assemblies are used in overhead valve (pushrod) engines and combine the rocker arm body, support bearings and pivot into a single unit. The bearing unit consists of two precision needle roller bearings that pivot on a shaft that is integral to the rocker arm assembly. The bearings have a full complement of needle rollers for maximum load capacity and durability.

Design Attributes

• Features a full complement of needle rollers for maximum load capacity and durability.
• Design provides improved bending stiffness and lower inertia characteristics over conventional sliding pivot rocker arms.
• All components are optimized to achieve maximum performance in a specific engine.

Applications

• Car and light truck overhead valve (pushrod) engines
