Product description
Electro-less nickel plating gives Works Z sprockets more of a brushed/natural stainless steel appearance but doesn''t compromise performance, durability or corrosion resistance
Constructed of the highest-quality stainless steel and 100% heat-treated for the ultimate combination of strength and durability
Unique offset tooth design for exceptional self-cleaning capabilities, extending the life of the entire chain drive system by removing mud and dirt more efficiently
Perfect for use in adverse off-road conditions where extremely wet, muddy and/or sandy conditions are encountered
Up to 50% lighter than the OEM steel (depending on application and number of sprocket teeth)
Twice the hardness of standard steel and 20% laterally stronger up to three times the overall life
Five times the hardness and durability of aluminum and up to 10 times the overall life
Include matching hardware set (nuts, bolts and washers)
Used by top teams and riders in GNCC, WORCS and motocross
