VHM pistons are 100% CNC machined from high quality material and have a non-circular profile to better prevent engine lockups. They stand for high performance, longevity and keeping high performance during it's lifetime. This piston consists of an inside coating, which reduces micro welding, lowers the friction on the pin, prevents piston bore galling and provides a very good thermal conduction. Furthermore, this piston includes special Z-clips, which prevents the clips from circling and affecting the groove.

Piston can be used as direct replacement for A-kits.

For non-A-kits, this piston must be used with a special VHM insert for flat top piston.
