Haojue HJ150 Rocker Arm, Motorcycle Engine Valve Rocker Arm Assembly

This HJ150 rocker arm assembly is premium aftermarket engine spare part specially designed for Haojue HJ150 series 150cc motorcycles.

Manufactured from high-grade alloy steel and processed by CNC precision machining, each rocker arm undergoes vacuum heat treatment and precision surface grinding. The finished product owns outstanding hardness, impact resistance and excellent wear resistance, which can sustain long-time high-temperature working environment inside the engine without deformation or rapid abrasion.

As a core component of the valve train system, the rocker arm transfers power from the camshaft to accurately control the opening and closing of intake and exhaust valves. It maintains precise valve timing, stabilizes engine power output and effectively reduces abnormal valve rattling noise. It can perfectly fix common engine faults such as worn rocker contact surface, valve stuck, power drop, rough idle and abnormal knocking sound.

Strictly machined according to OEM dimension standards. The size matches the original mounting position perfectly, supports direct bolt-on installation without cutting or extra modification. Great choice for regular motorcycle maintenance, full engine overhaul and repair shops.

Every rocker arm set passes strict quality inspection before shipment to ensure stable performance and longer service life. Cost-effective replacement spare parts for individual riders and wholesale distributors.
