I received a variator locking tool for my 50cc 139QMB Chinese scooter engine and it really works great! The best thing about it is that now I can change a belt on the road with just a few hand tools. That's piece of mind. I've seen similar tools for other makes but none for my engine till now. Thanks ZTR!  Dave Fox

Anti-Fade Z-Nut PDF Print E-mail

This is the ultimate anti-fade nut.

Q:  What is an anti-fade nut?

A:  An anti-fade nut is used to attach and retain an axle to a swingarm.

The Z-Nut is more lightweight and economical than any other anti-fade nut available.  The Z-Nut is precision CNC machined with proprietary technology so that it can maintain its installed torque on an axle in a vibration environment.
