GY6 180cc Rocker Arm Assembly

GY6 180cc Rocker Arm Assembly for GY6 QMI/QMJ 152/157 and Polaris Ranger RZR 170

This rocker arm assembly from the GY6 180cc range is built to work with the GY6 180cc Big Bore Power Kit. The set includes two rocker arms and two rocker arm shafts. Among GY6 scooter parts, it plays a key role in keeping the engine running well. If you notice low compression, ticking sounds, or burnt valves, this piece could be the right replacement.

Function Overview

In a four-stroke engine, the rocker arm assembly controls how the valves open and close, working alongside the cylinder head and camshaft to keep that timing in step. If these parts are worn or not working properly, the cylinder head may need attention so the engine can breathe efficiently.
