Details

  • The Works Z now is finished with electro-less nickel plating which gives the sprocket more of a brushed/natural stainless appearance but does not compromise in performance, durability, corrosion resistance, etc.
  • Constructed of the highest quality, stainless steel and 100% heat treated for the ultimate combination of strength and durability.
  • Unique, exclusive off set 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 using in adverse off road conditions where extremely wet, muddy and/or sandy conditions are encountered.
  • Up to 50% lighter than the same part in standard steel (depends on application and number of teeth).
  • Twice the hardness of standard steel and 20% laterally stronger; up to 3 times the overall life.
  • 5 times the hardness of aluminum and up to 10 times the overall life.
  • Includes matching hardware set (nuts, bolts, washers).

Suntar best ever
This is a great product this is my 3rd 1
. They used to have them in black but silver works though. Its steel and offset teeth are great for mud and sand I think it's the best sprocket made.

Great sprocket
This is the most durable sprocket I have bought. Clean out really well and holds up to the torque of a modified 4 stroke.

Sunstar Z
I have 124 hours on this sprocket it is still not worn out, slightly heavier than aluminum. Because the Z sprocket is thinner than conventional sprockets I had some concern about chain wear, that was not a issue at all. Excellent sprocket.
