GY6 Gear Up Kit
Are you looking for more top speed? This kit will increase your top speed, however you will loose some low end power do 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 come with everything to complete the install. All you need is 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. The 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 details.
This will work with the Chinese QMI152 or QMJ157 engine (GY6 Ruckus swapped engines)
