HPI LC+ A PULLEY

By increasing the outer diameter of the pulley, excessive rotation of the water pump at high rotation is suppressed and cavitation (foaming) is prevented.
In other words, Low Cavitation → Lc, and “+ α” have an inner fin attached to the pulley body to generate a cooling effect!
It generates wind to cool the water pump itself and efficiently discharge the hot air inside the radiator shroud to the outside of the engine room.
The tough design of the pulley body ensures top-class strength in aluminum pulleys, and hard alumite treatment ensures further strength.
