About this product
The Sunstar Works Z Steel Rear Sprocket delivers unmatched durability and performance for demanding off-road conditions. Built to withstand the rigors of GNCC, WORCS, and motocross, this sprocket is engineered for longevity and reliability, ensuring your chain drive system operates at its peak.
Description
Constructed from premium stainless steel and fully heat-treated, the Sunstar Works Z Rear Sprocket offers an exceptional combination of strength and durability. Its electro-less nickel plating provides a natural stainless steel appearance while enhancing corrosion resistance. The unique offset tooth design ensures exceptional self-cleaning, efficiently removing mud and dirt to extend the life of the entire chain drive system. This sprocket is perfect for riders who frequently encounter wet, muddy, or sandy conditions. The Works Z sprocket is up to 50% lighter than OEM steel sprockets (depending on the application and number of teeth) while offering twice the hardness of standard steel and 20% greater lateral strength, resulting in up to three times the overall lifespan. Compared to aluminum sprockets, it boasts five times the hardness and durability, with up to ten times the overall life.
