Want more top speed without losing all your acceleration? This lightweight ProBld gear-up kit improves final drive ratio while reducing rotating mass — meaning faster spool-up and a noticeable bump in speed 🏁⚙️
- ⚡ 20% lighter rotating mass for snappier acceleration
- 🏎️ Increased top speed over stock gearing
- 🔧 Includes everything needed for install (even gear oil)
The Details ⚙️
This ProBld lightweight gear-up system is designed to give you the best of both upgrades: reduced rotational mass for quicker revs, and a taller final drive ratio for higher top speed. The lighter gearing makes your engine spin up faster than traditional gear-up kits, which helps balance out the natural low-end loss that comes with taller gearing.
Depending on your setup, you may notice reduced low-speed torque — that’s normal when increasing final drive. If your engine already has solid torque, this kit will shine. If not, pairing it with upgrades like a variator slider, CVT tuning, or a big bore kit will make a huge difference 💪
Installation is straightforward and only requires basic hand tools and a press. If you don't have access to a press, no problem — we offer a pre-pressed option so the gears arrive ready to drop in.
Designed, tested, and run on multiple GY6 builds — this setup wasn’t guessed, it was dialed in through real miles.
Limited batches are made at a time — if you’ve been waiting for the lightweight version, now’s the time ⏳🔥
What's Included 📦
- 🦾 Lightweight ProBld gear-up gears
- 🧴 Pre-measured gear oil
- ⚙️ Gearbox gasket
- 🔧 Optional pressed-together countershaft (if selected)
- 📏 Final drive ratio matched to your engine size (selected in dropdown)
Important Things to Note 🚨
- Designed for QMI152 or QMJ157 (GY6) engines — including swapped Ruckus setups.
- Expect a slight low-end loss unless your build already has added torque.
- Best installed during a CVT service or gearbox maintenance.
- If selecting the pressed version, install becomes plug-and-play 🧩
- Will not fit the QMK161 engine (the pressed gear we use is different)
Not sure which ratio fits your engine size or build? Reach out — we’ll help dial it in 👍
