    This is a complete kit to increase the reduction of a BB220 gearbox by an additional 4:1

    Important Notes:

    The ringgears are marked with a dimple pattern that represents the stage. 2 dimples is a single stage and 4 dimples is an output stage. This 4:1 Add on Stage ringgear is marked with one set of 2 dimples. In order to add a stage, you must use a ringgear that is marked with one set of 2 dimples, and it must be added to the motor side.

    Every gearbox must have one and only one ringgear marked with a set of four dimples and it must be the ringgear next to the output shaft.

    You CAN NOT use this kit as a replacement for the output stage of a stock gearbox - the carrier plate and ringgear are different.
