Installation and Gear Ratio Note

Before ordering, check the model, year, chain pitch, and required number of teeth.
A different number of teeth changes the gear ratio and may require a different chain length or adjustment of the chain tension.
Perform installation and tightening torques according to the vehicle manufacturer's specifications.
