Data Sheet

Taller gears reduce the overall gear ratio of your transmission and will result in improved acceleration, and with a powerful enough cylinder, top speed will not be affected (or can even be increased). OEM engines usually don't have enough power to pull this kind of transmission, so you will need a sports or racing cylinder.

Unlike many other transmissions, Stage6 transmissions are pre-pressed - and available at a knock-out price! All you have to do is get rid of your old transmission and replace them with this one, close the cover - done!
