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 👍
