GY6 Light Weight Gear Up Kit (Includes Pressed Gears, Gasket & Oil)

This is our new ProBld light weight gear up kit (20% lighter). Lighter rotating mass helps the engine spool up faster, giving you a bit of both worlds; revs up faster then a traditional final drive gears, while increasing the top speed.

Do keep in mind, this kit will increase your top speed, however you will loose some low end power due to the higher gearing. If your engine has more than enough bottom end power, this will work out perfect! If not, we recommend a big bore kit, variator slider, or even a CVT kit.

This gear up kit comes with everything to complete the install. All you need are basic tools and a press. If you don't have a press, no problem. We can press the gears into a new counter shaft gear before we send them out. This will make for an extremely easy install. The kit will come with pre-measured gear oil, our secret gear ratio for your specific engine size (choose in drop down), and the gear box gasket. Watch the video for more details.

This will work with the Chinese QMI152 or QMJ157 engine (GY6 Ruckus swapped engines).
