This set of eight rocker arms is a critical component of the engine's valve train system, controlling the opening and closing of intake and exhaust valves. Manufactured to meet stringent OEM standards, these arms ensure precise valve timing and lift, unlike worn components that can lead to reduced engine performance and efficiency. Operators may notice a loss of engine power, rough idling, or increased exhaust smoke when rocker arms begin to fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of rocker arm failure may include ticking or tapping noises from the engine. If ignored, this can progress to a noticeable loss of engine power and increased fuel consumption. Continued operation with worn rocker arms can lead to improper valve sealing and potential damage to the camshaft and cylinder head.
Ensure the camshaft is at the base circle position for the affected cylinder before removing or installing rocker arms to avoid valve train stress. Do not overtighten the rocker arm adjusting screws, as this can damage the valve stem or seat.
Inspect the valve springs, valve seals, and camshaft lobes for wear or damage when replacing rocker arms.
