Rocker Arm

The basic function of rocker is to open or close the inlet or exhaust valve with respect to the motion of the cam and follower. It is designed with respect to the bending stress generated because of gas pressure on valve, the inertia forces of valve, and spring force to hold the valve.

Freya Engineering rocker arm products are easy to fix, time saving while fixing it in the engine because of 100% precision in our products.

Why Our Rocker Arm

Design & Performance Features

Every rocker arm is engineered to exacting standards and validated through comprehensive testing before delivery.

Valve Train Precision

Engineered to open and close inlet and exhaust valves with exact timing, reducing wear and improving engine efficiency.

Investment Casting Process

Near-net shape casting with complex geometries, superior surface finish, and minimal material waste compared to conventional methods.

EN8 Grade Material

Medium carbon steel with excellent tensile strength and toughness — ideal for high-stress, high-cycle valve train applications.

Bending Stress Design

Designed to withstand bending stress from gas pressure, valve inertia forces, and spring return forces across the full engine RPM range.

100% Inspection

Every component passes multi-point dimensional, hardness, and surface finish inspection before shipment — zero compromise on quality.

Easy & Fast Assembly

100% precision manufacturing means our rocker arms fit perfectly first time — saving time and reducing assembly errors in production lines.
