High quality, all steel sprockets meet the demands of todays highest horsepower machines
Powerdrive countershaft (front) sprockets are manufactured from case-hardened chromoly steel for the ultimate in strength and durability
They also receive a parkerizing surface treatment for rust and corrosion resistance
Sunstar steel rear sprockets are manufactured from the highest quality 1045 high-carbon steel and most are heat treated for added strength and wear resistance
Computer designed weight reduction holes are included where possible
Most rear sprockets are zinc plated and some have a baked-on durable paint for corrosion resistance
NOTE: Any time you use other than the standard front/rear sprocket sizes, clearance must be checked. When converting to a smaller chain size, especially for racing,be sure to use the highest grade O-ring chain available (non-O-ring heavy duty acceptable for drag racing).
