Description
Designed for extreme environments, the Works Z steel rear sprocket features an electro-less nickel plating that provides a unique brushed stainless steel appearance without sacrificing performance or corrosion resistance. Its unique offset tooth design ensures exceptional self-cleaning capabilities, effectively removing mud and dirt to extend the life of your entire chain drive system. Up to 50% lighter than OEM steel sprockets (depending on the application and number of teeth), the Sunstar Works Z offers improved performance without compromising strength. This sprocket is twice as hard as standard steel, 20% laterally stronger, and offers up to three times the overall life. When compared to aluminum sprockets, it boasts five times the hardness and durability, and up to 10 times the overall life. Used by top teams and riders in GNCC, WORCS, and motocross, the Sunstar Works Z steel rear sprocket is the ultimate choice for serious riders.
