Shacman Delong Sinotruk HOWO Truck Spare Parts Valve Rocker Arm Assembly 1003189325 Rocker Arm Complete

Alloy Steel Construction: Forged from high-strength alloy steel and heat-treated, this component offers excellent mechanical strength and fatigue resistance, enabling it to withstand the impact loads encountered during engine operation without fracturing or deforming.

Wear-Resistant Roller: The contact surface between the roller and the valve undergoes a wear-resistant treatment, effectively minimizing wear, reducing noise and extending service life.

Optimized Force Transmission: The rocker arm features an optimized design that ensures even force distribution, enhancing operational stability under high-load and high-RPM conditions.

Precise Exhaust Control: Working in conjunction with the valve assembly, this component transfers cam motion to the exhaust valve, ensuring the valve opens and closes correctly in accordance with the engine's valve timing sequence.
