Maintain precise valve operation and dependable engine performance with this Genuine Nissan Exhaust Rocker Arm, designed to suit Nissan Patrol GU Y61 TD42T diesel models. This OEM rocker arm is fitted within the cylinder head and is responsible for actuating the exhaust valves, ensuring efficient exhaust gas flow and correct engine breathing under all operating conditions.

Over time, rocker arms are exposed to constant mechanical load, oil pressure fluctuations, and high engine temperatures. A worn or damaged rocker arm can lead to excessive valve train noise, reduced engine performance, poor combustion efficiency, and potential damage to associated valvetrain components. Replacing worn rocker arms during servicing helps restore correct valve operation and protects the engine’s top-end assembly.

Manufactured to genuine Nissan specifications, this direct-fit replacement delivers accurate geometry, strong wear resistance, and long-lasting durability for both daily driving and demanding off-road use.
