VHM pistons are 100% CNC machined from high quality solid billet material. With our Takisawa lathe we are able to turn elliptical shaped pistons with very high precisions. This reduces engine lockups. Another feature of most of our pistons is an inside coating, which reduces micro welding, lowers the friction on the pin, prevents piston bore galling and provides a very good thermal conduction.
We produce two piston models: direct replacement and special models. The direct replacement pistons are a standard model, which can be placed into your engine with no other adjustments needed. The special models are for maximum performance gain, which can only be used in your engine together with a special VHM insert or for example with a longer connecting rod.
